[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0030] The descriptions of “first, second, third” etc. that appear in the embodiments of the present application are only for illustration and distinction of the description objects. There is no distinction of order, nor do they indicate any special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application.

[0031] The “connection” that appears in the embodiments of the present application may be a direct connection or an indirect connection, that is, other devices are connected to the circuit between the two ends of the electrical connection.

[0032] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0033] Figure 1 A network architecture that may be applicable to the embodiments of the present application is shown. Figure 1As shown, the network architecture provided in this embodiment includes: network device 101 and terminal 102. The terminal involved in the embodiment of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user terminal devices (terminal device) or mobile stations (MobileStation, MS), etc. The network device involved in the embodiment of the present application is a device deployed in a wireless access network to provide wireless communication functions for the terminal. In the embodiment of the present application, the network device can be, for example, Figure 1 The base station shown may include various forms of macro base stations, micro base stations, relay stations or access points, etc. The base station may be a generation Node B (gNB) in a 5G New Radio (NR) system, an evolutionary Node B (eNB) in a 4G Long Term Evolution (LTE) system, etc.

[0034] There are many ways of satellite communication at present, as shown in Table 1, which are the more common forms.

[0035] Table 1

[0036]

[0037] From the data in Table 1, it can be seen that the transmission of satellite communications is concentrated in the MB (medium frequency) section. Except for the relatively high frequency of Tiantong satellite, the other standards are between 1.5GHz and 1.6GHz, and the receiving frequency band includes MB (medium frequency) and HB (high frequency). In addition, from a technical perspective, satellite communications all use time division duplexing (TDD), but some satellite communication methods use the same frequency for uplink and downlink, while some use different frequencies for uplink and downlink (based on the bandwidth and carrying capacity of the communication).

[0038] A complete RF system block diagram for satellite communications is shown below: Figure 2 As shown, the cellular communication transceiver 206 supports the processing of transceiver signals of the cellular communication system, and the satellite communication transceiver 207 supports the processing of transceiver signals of the satellite communication system. Figure 2It can be seen that no matter which satellite communication method is used, additional power amplifiers (PA) must be added. High-power PAs provide strong support for the uplink signal of the entire satellite communication RF system. Currently, due to the lack of protocol interoperability between various satellite communication RF systems, there are also inconsistencies in PA system solutions. However, from a physical point of view, a wide-band PA is sufficient to support the transmission of satellite communication signals. Physically, the signal frequencies are all concentrated between MB (medium frequency) 1GHz-2.4GHz;

[0039] The need for a low noise amplifier (LNA) for receiving signals is also a strong requirement. Currently, due to the lack of interaction between satellite communication systems and cellular communication systems, some components cannot be reused. Physically, LNA also has a frequency range. From the current technical solutions, it can be seen that the operating frequency of satellite communication is basically covered in the MHB (medium and high frequency) frequency. For example, the downlink of Globalstar involves the high frequency band (2.5GHz).

[0040] Because the receiver system itself involves security and other information, it is difficult to integrate satellite communication receivers and cellular communication receivers. For example, it is difficult to integrate the Iridium satellite system with the Tiantong satellite system or the Maritime satellite system developed by other operators different from the system.

[0041] With the development of mobile communication networks, from the initial 2G network that only supports voice calls to the current 5G network that supports high-speed data traffic, mobile communication networks are providing convenience for people's daily lives. But the difficulty that comes with it is that with the increase in communication network standards, terminal equipment must support communication requirements under various network standards such as 2G, 3G, 4G, and 5G. However, due to the size constraints of terminal equipment, the space of the motherboard PCB has not been greatly increased due to the increase in demand, which will lead to very tight space layout and wiring of the motherboard PCB.

[0042] In order to cope with the increasing demand for various network standards and solve the problem of tight PCB layout, the high integration and miniaturization of devices have become a development trend. From the Phase 2 products that only support Single Band at the beginning to the Phase 7 products that support the integration of various standards, the integration of devices is getting higher and higher, and the package size of devices is getting smaller and smaller. In a typical MHB L-PAmid framework, it has multiple MHB LNA modules inside, among which MHB LNA can support all satellite communication receiving bands currently on the market; in addition, there are three PA bands inside the device, namely MB, HB and B7 high-frequency PAs. The support frequency for MB can cover the satellite communication band. At the same time, the front-end antenna also covers the MHB working range, and the working frequency of this section just meets the requirements of satellite communication.

[0043] In the relevant schemes, the core impact point lies in the complex front-end system and has no intersection with the current terminal. All peripheral devices of the satellite communication system are plug-in. However, the completely independent design thinking leads to the poor performance of the PCB routing due to long wiring. At the same time, the cost and area of ​​the external devices are also unavoidable. Therefore, apart from the impact of the receiver (because the security mode involved in different satellite systems cannot be avoided), all other external devices (such as PA, antenna, switch and LNA) are a cumbersome design for the current terminal design, with a cost of about 3￥ and an area of ​​about 36mm^2, as shown in Table 2;

[0045]

[0046] In view of this, an embodiment of the present application provides a wireless communication device, Figure 3 A schematic diagram of the structure of a wireless communication device provided in an embodiment of the present application, such as Figure 3 As shown, the wireless communication device 3 includes a first RF front-end module 30, and the first RF front-end module 30 includes an antenna port module 301 (including at least one antenna port), a first PA 302, a first LNA 303 and a switch module 304; wherein the working frequency band of the first PA 302 includes the first working frequency band of the satellite communication system and the second working frequency band of the cellular communication system, and / or, the working frequency band of the first LNA 303 includes the third working frequency band of the satellite communication system and the fourth working frequency band of the cellular communication system;

[0047] A switch module 304, used for conducting a path between the first PA 302 and a certain antenna port 301 in the antenna port module 301, so as to transmit the transmission signal of the first working frequency band or the second working frequency band amplified by the first PA 302 to the connected antenna through the antenna port;

[0048] The switch module 304 is further used to connect a certain antenna port in the antenna port module 301 to the first LNA 303 , so as to transmit the reception signal of the third working frequency band or the fourth working frequency band received by the antenna port to the first LNA 303 .

[0049] In an embodiment of the present application, a wireless communication device is provided, in which a satellite communication system and a cellular communication system share at least one PA and / or at least one LNA; the shared PA supports both the operating frequency band of the satellite communication system and the operating frequency band of the cellular communication system, and the shared LNA supports both the operating frequency band of the satellite communication system and the operating frequency band of the cellular communication system; in this way, while ensuring the communication performance of the satellite communication system and the cellular communication system, the hardware area and hardware cost of the wireless communication device can be saved.

[0050] Furthermore, in some embodiments, Figure 4 As shown, the wireless communication device 3 also includes an antenna 31 connected to the antenna port, the transmitting frequency band of the antenna 31 includes the first working frequency band and the second working frequency band, and / or the receiving frequency band of the antenna 31 includes the third working frequency band and the fourth working frequency band.

[0051] It can be understood that in the wireless communication device 3, if the working frequency band of the first PA 302 includes the first working frequency band of the satellite communication system and the second working frequency band of the cellular communication system, the transmitting frequency band of the antenna 31 includes the first working frequency band and the second working frequency band, that is, the antenna 31 supports the transmission of wireless signals of the first working frequency band and the second working frequency band. If the working frequency band of the first LNA 303 includes the third working frequency band of the satellite communication system and the fourth working frequency band of the cellular communication system, the receiving frequency band of the antenna 31 includes the third working frequency band and the fourth working frequency band, that is, the antenna 31 supports the reception of wireless signals of the third working frequency band and the fourth working frequency band.

[0052] It can be understood that the antenna port is connected to an antenna, so the number of antenna ports is the same as the number of antennas in the wireless communication device 3. The models of antennas connected to different antenna ports can be the same or different.

[0053] In the embodiment of the present application, the number of antenna ports included in the first RF front-end module 30 is not limited, and any number of antenna ports may be included. Figure 5 As shown, the at least one antenna port module 301 includes a first antenna port 3011 and a second antenna port 3012 , the first antenna port 3011 is connected to the first antenna 311 , and the second antenna port 3012 is connected to the second antenna 312 .

[0054] In the embodiment of the present application, there is no limitation on the number of switches included in the switch module 304 and the connection relationship with other devices in the first RF front-end module 30. In short, the switch module 304 can conduct the path between the first PA 302 and an antenna port in the antenna port module 301, and / or the path between an antenna port in the antenna port module 301 and the first LNA 303.

[0055] In one possible implementation, the switch module 304 may include a first switch and a second switch; in another possible implementation, the switch module 304 includes not only the first switch and the second switch, but also a third switch and a fourth switch.

[0056] Specifically, in some embodiments, Figure 6 As shown, the switch module 304 includes a first switch 3041 and a second switch 3042; wherein the first antenna port 3011 is connected to the first end of the first switch 3041, the second antenna port 3012 is connected to the second end of the first switch 3041, the third end of the first switch 3041 is connected to the first end of the second switch 3042; the second end of the second switch 3042 is connected to the output end of the first PA 302; and the third end of the second switch 3042 is connected to the input end of the first LNA 303.

[0057] based on Figure 6 The wireless communication device 3 shown, for the transmission channel, has an operating principle as described below: the second switch 3042 is used to conduct the connection between the second end of the second switch 3042 and the first end of the second switch 3042, and correspondingly, the first switch 3041 is used to conduct the connection between the third end of the first switch 3041 and the first end or the second end of the first switch 3041, so as to transmit the transmission signal amplified by the first PA 302 to the connected antenna through the first antenna port 3011 or the second antenna port 3012.

[0058] Understandably, Figure 6In the wireless communication device 3 shown, the signal flow of the transmission signal is described as follows: the transmission signal (which may be a cellular communication signal or a satellite communication signal) is input to the first PA 302, amplified by the first PA 302 and output to the second end of the second switch 3042, and then transmitted to the third end of the first switch 3041 via the conductive channel / closed channel between the second end of the second switch 3042 and the first end of the second switch 3042, and then transmitted to the first antenna port 3011 via the conductive channel / closed channel between the third end of the first switch 3041 and the first end of the first switch 3041, and then the transmission signal is transmitted through the first antenna 311; or, after reaching the third end of the first switch 3041, the transmission signal is transmitted to the second antenna port 3012 via the conductive channel / closed channel between the third end of the first switch 3041 and the second end of the first switch 3041, and then the transmission signal is transmitted through the first antenna 312.

[0059] based on Figure 6 The wireless communication device 3 shown in the figure has a working principle as follows for one receiving channel: the first switch 3041 is used to conduct the connection between the second end of the first switch 3041 and the third end of the first switch 3041, and correspondingly, the second switch 3042 is used to conduct the connection between the first end of the second switch 3042 and the third end of the second switch 3042, so as to transmit the first receiving signal or the second receiving signal received by the second antenna 312 to the input end of the first LNA 303; wherein the first receiving signal belongs to the third working frequency band of the satellite communication system, and the second receiving signal belongs to the fourth working frequency band of the cellular communication system.

[0060] Understandably, Figure 6 In the wireless communication device 3 shown, the signal flow of the received signal is described as follows: after receiving the received signal, the second antenna 312 enters the second end of the first switch 3041 through the second antenna port 3012 connected thereto, and then passes through the conductive channel / closed channel between the second end of the first switch 3041 and the third end of the first switch 3041 to the first end of the second switch 3042, and then passes through the conductive channel / closed channel between the first end of the second switch 3042 and the third end of the second switch 3042 to enter the first LNA 303. The received signal may be the first received signal or the second received signal.

[0061] based on Figure 6For the wireless communication device 3 shown, for another receiving channel, that is, the third receiving signal received by the first antenna 311 can be processed by the first LNA 303 inside the first RF front-end module 30 or the third LNA inside the first RF front-end module 30, or by the second LNA in the second RF front-end module; wherein the working frequency band of the third LNA at least includes the third working frequency band of the satellite communication system. The working frequency band of the third LNA can also include the fourth working frequency band of the cellular communication system.

[0062] For example, in some embodiments, Figure 7 As shown, the wireless communication device 3 also includes a second RF front-end module 32, the second RF front-end module 32 includes a second LNA 321, and the working frequency band of the second LNA 321 includes the third frequency band of the satellite communication system; in order to enable the third receiving signal received by the first antenna 311 to be processed by the second LNA 321 in the second RF front-end module 32, in the wireless communication device 3, the fourth end of the second switch 3042 is connected to the input end of the second LNA 321.

[0063] Understandably, Figure 7 The wireless communication device 3 shown is Figure 6 The working principle of the transmission channel of the wireless communication device 3 shown is the same, that is, the signal flow of the transmission signal to be amplified by the first PA 302 is the same, so it is not repeated here.

[0064] based on Figure 7 The wireless communication device 3 shown in the figure has a receiving channel for receiving a signal received by the second antenna 312. Figure 6 The wireless communication device 3 shown in FIG. 1 is the same as that shown in FIG. 1 , so it will not be described here in detail. As for another receiving channel, its working principle is described as follows: the first switch 3041 is also used to conduct the connection between the first end of the first switch 3041 and the third end of the first switch 3041; correspondingly, the second switch 3042 is also used to conduct the connection between the first end of the second switch 3042 and the fourth end of the second switch 3042, so as to transmit the third receiving signal received by the first antenna 311 to the input end of the second LNA 321; wherein the third receiving signal belongs to the third working frequency band of the satellite communication system, the first antenna 311 is used as a diversity receiving antenna, and the second antenna 312 is used as a main receiving antenna.

[0065] Understandably, Figure 7In the wireless communication device 3 shown, the signal flow of the third received signal is described as follows: after the first antenna 311 receives the third received signal, the third received signal enters the first end of the first switch 3041 through the first antenna port 3011 connected thereto, and then is input to the second LNA 321 via the conduction channel / closed channel between the first end of the first switch 3041 and the fourth end of the first switch 3041.

[0066] As described above, in one possible implementation, the structure of the switch module 301 as described above may include a first switch 3041 and a second switch 3042; in another possible implementation, the switch module 304 includes not only the first switch 3041 and the second switch 3042, but also a third switch and a fourth switch.

[0067] Specifically, for another possible implementation, in some embodiments, such as Figure 8 As shown, the switch module 304 further includes a third switch 3043 and a fourth switch 3044; wherein,

[0068] The first antenna port 3011 is connected to the first end of the first switch 3041 through the fourth switch 3044. The specific connection relationship includes: the first antenna port 3011 is connected to the first end of the fourth switch 3044, and the second end of the fourth switch 3044 is connected to the first end of the first switch 3041;

[0069] The second antenna port 3012 is connected to the second end of the first switch 3041 through the third switch 3043. The specific connection relationship includes: the second antenna port 3012 is connected to the first end of the third switch 3043, and the second end of the third switch 3043 is connected to the second end of the first switch 3041;

[0070] A third terminal of the third switch 3043 is connected to the input terminal of the first LNA 303 .

[0071] based on Figure 8The wireless communication device 3 shown in the figure, for the transmission channel, its working principle is described as follows: the second switch 3042 is used to conduct the connection between the second end of the second switch 3042 and the first end of the second switch 3042; correspondingly, the first switch 3041 is used to conduct the connection between the third end of the first switch 3041 and the first end or the second end of the first switch 3041; the third switch 3043 is used to conduct the connection between the second end of the third switch 3043 and the first end of the third switch 3043 when the third end of the first switch 3041 is conducted with the second end of the first switch 3041, so as to transmit the transmission signal amplified by the first PA 302 to the connected second antenna 312 through the second antenna port 3012; the fourth switch 3044 is used to conduct the connection between the second end of the fourth switch 3044 and the first end of the fourth switch 3044 when the third end of the first switch 3041 is conducted with the first end of the first switch 3041, so as to transmit the transmission signal amplified by the first PA 302 to the connected first antenna 311 through the first antenna port 3011.

[0072] Understandably, Figure 8 In the wireless communication device 3 shown in FIG. 1 , the signal flow of the transmission signal is described as follows: the transmission signal (which may be a cellular communication signal or a satellite communication signal) is input to the first PA 302, and the first PA 302 transmits the signal to the first PA 302. The signal is amplified by the first antenna 302 and then output to the second end of the second switch 3042. The signal is then output to the third end of the first switch 3041 through the conducting channel / closed channel between the second end of the second switch 3042 and the first end of the second switch 3042. The signal is then output to the second end of the fourth switch 3044 through the conducting channel / closed channel between the third end of the first switch 3041 and the first end of the first switch 3041. The signal is then input to the first antenna port 3011 through the conducting channel / closed channel between the second end of the fourth switch 3044 and the first end of the fourth switch 3044, and the transmission signal is then transmitted through the first antenna 311. Alternatively, the signal is output to the third end of the first switch 3041 and then to the second end of the third switch 3043 through the conducting channel / closed channel between the third end of the first switch 3041 and the second end of the first switch 3041. The signal is then input to the second antenna port 3012 through the conducting channel / closed channel between the second end of the third switch 3043 and the first end of the third switch 3043, and the transmission signal is then transmitted through the first antenna 312.

[0073] based on Figure 8The wireless communication device 3 shown, for one receiving channel, has an operating principle as described below: the third switch 3043 is used to conduct the connection between the first end of the third switch 3043 and the third end of the third switch 3043, so as to transmit the first receiving signal or the second receiving signal received by the second antenna 312 to the input end of the first LNA 303; wherein the first receiving signal belongs to the third working frequency band of the satellite communication system, and the second receiving signal belongs to the fourth working frequency band of the cellular communication system.

[0074] Understandably, compared Figure 6 The circuit structure shown in Figure 8 In the circuit structure shown, the first reception signal or the second reception signal received by the second antenna 312 can reach the first LNA 303 without passing through the second switch 3042 ; thus, the insertion loss of the first reception signal or the second reception signal is reduced, which is beneficial to enhance communication performance.

[0075] Understandably, Figure 8 In the wireless communication device 3 shown, the signal flow of the received signal (such as the first received signal or the second received signal) is described as follows: after the second antenna 312 receives the received signal, it enters the first end of the third switch 3043 through the second antenna port 3012 connected thereto, and then enters the first LNA 303 through the conduction channel between the first end of the third switch 3043 and the third end of the third switch 3043.

[0076] based on Figure 8 For the wireless communication device 3 shown, for another receiving channel, that is, the third receiving signal received by the first antenna 311 can be processed by the first LNA 303 inside the first RF front-end module 30 or the third LNA inside the first RF front-end module 30, or by the second LNA in the second RF front-end module; wherein the working frequency band of the third LNA at least includes the third working frequency band of the satellite communication system. The working frequency band of the third LNA can also include the fourth working frequency band of the cellular communication system.

[0077] For example, in some embodiments, Fig. 9 As shown, the wireless communication device 3 also includes a second RF front-end module 32, the second RF front-end module 32 includes a second LNA321, and the working frequency band of the second LNA321 includes the third frequency band of the satellite communication system; the third end of the fourth switch 3044 is connected to the input end of the second LNA321.

[0078] Understandably, Fig. 9 The wireless communication device 3 shown is Figure 8The working principle of the transmission channel of the wireless communication device 3 shown is the same, that is, the signal flow of the transmission signal to be amplified by the first PA 302 is the same, so it will not be described in detail here.

[0079] based on Fig. 9 The wireless communication device 3 shown in the figure has a receiving channel for receiving a signal received by the second antenna 312. Figure 8 The wireless communication device 3 is the same as that shown in FIG. 1 , and therefore will not be described in detail here. Fig. 9 In the wireless communication device 3 shown, for another receiving channel, its working principle is described as follows: the fourth switch 3044 is also used to conduct the connection between the first end of the fourth switch 3044 and the third end of the fourth switch 3044, so as to transmit the third receiving signal received by the first antenna 311 to the input end of the second LNA 321; wherein the third receiving signal belongs to the third working frequency band of the satellite communication system, the first antenna 311 is used as a diversity receiving antenna, and the second antenna 312 is used as a main receiving antenna.

[0080] Understandably, Fig. 9 In the wireless communication device 3 shown, the signal flow of the third received signal is described as follows: after the first antenna 311 receives the third received signal, it enters the first end of the fourth switch 3044 through the first antenna port 3011 connected thereto, and then is input to the second LNA 321 through the conductive channel / closed channel of the first end of the fourth switch 3044 and the third end of the fourth switch 3044.

[0081] In some embodiments, the wireless communication device 3 is a multiple input multiple output (MIMO) wireless communication device. The wireless communication device 3 includes at least two first RF front-end modules 30 , and different antenna ports are connected to different antennas.

[0085] In some embodiments, the wireless communication device 3 is a MIMO wireless communication device, and the wireless communication device 3 includes at least two first RF front-end modules 30 and a second RF front-end module 32 connected to the first RF front-end module, and different antenna ports are connected to different antennas.

[0086] For example, Fig.12 As shown, the third received signal of the first antenna 311 can be processed by the second LNA 321 in the second RF front-end module 32, and the first received signal or the second received signal of the second antenna 312 can be processed by the first LNA 303; wherein, the first RF front-end module 30 does not include the third switch 3043 and the fourth switch 3044.

[0087] Another example Fig.13 As shown, the third received signal of the first antenna 311 can be processed by the second LNA 321 in the second RF front-end module 32, and the first received signal or the second received signal of the second antenna 312 can be processed by the first LNA 303; wherein the first RF front-end module 30 includes a third switch 3043 and a fourth switch 3044.

[0088] In some embodiments, the wireless communication device 3 also includes a first transceiver, which is connected to the RF front-end module (such as the first RF front-end module and / or the second RF front-end module), and the first transceiver is used to convert the baseband signal output by the baseband processor into a corresponding transmission signal and then transmit it to the power amplifier in the first RF front-end module (such as the first PA or other power amplifier); the first transceiver is also used to convert the received signal processed by the low noise amplifier (such as the first LNA, the second LNA or other LNA) in the first RF front-end module or the second RF front-end module into a corresponding baseband signal.

[0089] In some embodiments, the wireless communication device 3 also includes a second transceiver, which is connected to the second RF front-end module. The second transceiver is used to convert the baseband signal output by the baseband processor into a corresponding transmission signal and transmit it to the power amplifier in the first RF front-end module (such as the first PA or other power amplifier); the first transceiver is also used to convert the received signal processed by the low-noise amplifier (such as the first LNA, the second LNA or other LNA) in the first RF front-end module or the second RF front-end module into a corresponding baseband signal.

[0092] In a possible implementation, for a transmission signal of a satellite communication system, the operating parameters of the first PA 302 may be optimized to increase its output power to meet the power output requirement of the satellite communication system.

[0093] In a possible implementation, the first RF front-end module 30 is an integrated module. For example, the RF front-end module 30 is an MHB L-PAMiD (such as Phase 7LE MHB L-PAMiD) or other types of RF front-end integrated modules.

[0094] In a possible implementation, the second RF front-end module 32 is an integrated module, and the RF front-end module 32 may be a RF front-end integrated module dedicated to the satellite communication system.

[0095] It can be understood that in the wireless communication device 3 provided in the embodiment of the present application, the comprehensive cost of the antenna, switch, LNA and PA can be saved. From the performance dimension, although the diversity loss increases due to the need to pass through the second switch, the additional MIMO1 / 2 can completely offset the increase brought by this part, and can even exceed the original performance. In addition, all peripheral devices of the satellite communication system are integrated into the RF front-end module, which greatly saves the hardware area, and the overall solution has a high degree of integration, without any external devices.
