Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a radio frequency circuit and electronic device. Background Technology

[0002] Electronic devices can be equipped with multiple wireless communication systems simultaneously to support different types of wireless communication. For example, an electronic device can be equipped with a cellular communication system to support cellular communication. Another example is a satellite communication system, which supports satellite communication.

[0003] Every wireless communication system requires a corresponding antenna, radio frequency (RF) module, and baseband module. The antenna is used for converting electromagnetic waves into analog signals, i.e., performing the transmission and reception of wireless signals. The RF module performs RF processing of analog signals. The baseband module performs processing of digital signals.

[0004] Since the space for antennas in electronic devices is limited, different wireless communication systems can reduce the number of antennas in electronic devices by reusing antennas.

[0005] For example, one or more switching components can be configured between the antenna and the radio frequency modules of different wireless communication systems. The electronic device can control the switching components to operate in different on states, thereby coupling the antenna with different radio frequency modules. This enables the multiplexing of the antenna by different wireless communication systems.

[0006] Understandably, the placement of switching components may increase signal transmission loss on the communication link. Therefore, to ensure the communication quality of various wireless communication systems, it is necessary to rationally configure switching components to reduce or eliminate signal transmission loss during antenna multiplexing. Summary of the Invention

[0007] This application provides a radio frequency circuit and electronic device that can reduce signal transmission loss in at least one system in a multi-system communication scheme.

[0008] To achieve the above technical objectives, this application adopts the following technical solution:

[0009] In a first aspect, a radio frequency (RF) circuit is provided, applied to an electronic device configured with at least two communication systems. The electronic device also includes a first antenna. The RF circuit includes at least one switching component and at least three RF channels. The at least one switching component includes a first switching component, which includes at least a first terminal, a second terminal, a third terminal, and a fourth terminal. The first switching component is configurable such that its first terminal is connected to either its second terminal, its third terminal, or its fourth terminal. The at least three RF channels include a first RF channel, a second RF channel, and a third RF channel. The first antenna is coupled to the first terminal of the first switching component. The second terminal of the first switching component is coupled to the first RF channel. The third terminal of the first switching component is coupled to the second RF channel. The fourth terminal of the first switching component is coupled to the third RF channel. The first RF channel and the second RF channel are different RF channels of a first communication system, and the third RF channel is a RF channel of a second communication system. The first communication system and the second communication system are included in the at least two communication systems, and the first communication system and the second communication system are different.

[0010] Based on this scheme, the first switching component can participate simultaneously in intra-system handover within the first communication system, as well as inter-system handover when the first and second communication systems reuse the first antenna. In other words, inter-system handover is achieved without adding additional switching components on top of intra-system handover. This avoids the increased link insertion loss caused by adding extra switching components to achieve inter-system antenna reuse.

[0011] Optionally, the operating frequency band of the first antenna includes a first frequency, wherein the first frequency is included in the overlapping portion of the corresponding frequencies of the first communication system and the second communication system. Alternatively, the first frequency is between a second frequency and a third frequency. The second frequency is included in the corresponding frequency of the first communication system, the third frequency is included in the corresponding frequency of the second communication system, and the bandwidth between the second frequency and the third frequency is less than 5% relative to the bandwidth of the third frequency.

[0012] This implementation provides specific limitations on the first antenna. In some implementations, the frequencies corresponding to the first and second communication systems may overlap, and the operating frequency of the first antenna can be included within this overlapping portion. In other implementations, the frequencies corresponding to the first and second communication systems may be spaced apart but close to each other. For example, consider a scenario where the frequency corresponding to the first communication system is lower than the frequency corresponding to the second communication system. The difference between the highest frequency (e.g., the second frequency) of the first communication system and the lowest frequency (e.g., the third frequency) of the second communication system, divided by the third frequency, gives the relative bandwidth of this frequency interval. If this relative bandwidth is less than 5%, it indicates that the operating frequencies of the two communication systems are very close. Thus, signal transmission and reception of the two communication systems can be effectively performed using a first antenna whose operating frequency is between the second and third frequencies.

[0013] Optionally, when the electronic device is operating, the first antenna is used for signal transmission and reception corresponding to the first communication system. The first switching component is configured in a first state, corresponding to the first terminal of the first switching component being connected to the second terminal of the first switching component. Alternatively, the first switching component is configured in a second state, corresponding to the first terminal of the first switching component being connected to the third terminal of the first switching component.

[0014] Optionally, the electronic device is equipped with a first baseband module, which corresponds to the first communication system. The first switching component is configured in a first state, including: the first baseband module controlling the first switching component to operate in the first state or the second state.

[0015] This clarifies the working mechanism of the first switching component when participating in the internal handover of the first communication system. It can be understood that, in the handover scenario within this system, the first switching component can be controlled by the baseband module or modem corresponding to the first communication system.

[0016] Optionally, when the electronic device is operating, the first antenna is used for signal transmission and reception corresponding to the second communication system. The first switching component is configured in a third state, which corresponds to the first terminal of the first switching component being connected to the fourth terminal of the first switching component.

[0017] Optionally, the electronic device is equipped with a second baseband module, which corresponds to the second communication system. The first switching component is configured in a third state, including: the second baseband module controlling the first switching component to operate in the third state.

[0018] This clarifies the working mechanism of the first switching component when it participates in the system switching between the first and second communication systems. It can be understood that, in this system switching scenario, the first switching component can be controlled by the baseband module or modem corresponding to the second communication system, or by the coordinated control of the second and first communication systems.

[0019] Optionally, the at least two communication systems in the electronic device include at least two of the following: cellular communication system, satellite communication system, Wi-Fi communication system, and GPS communication system. It is understood that the technical solution provided in this application can be applied to any two or more communication systems with overlapping frequencies, reducing the increase in insertion loss caused by system switching and improving communication quality.

[0020] Optionally, the satellite communication system may include: the Tiantong satellite communication system and / or the Beidou satellite communication system.

[0021] Optionally, each of the communication systems includes a corresponding radio frequency (RF) channel and a baseband module, with the at least one switching component used to couple the antenna in the electronic device to the corresponding RF channel. For example, the baseband module can be used for digital signal processing within the corresponding system. In some implementations, where the baseband module integrates a modem, it can also be used to control the on / off state of the switching components associated with the system.

[0022] Optionally, the first switching component further includes a fifth terminal, and the first switching component can also be configured such that the first terminal of the first switching component is connected to the fifth terminal of the first switching component. The radio frequency circuit also includes a fourth radio frequency channel. This fourth radio frequency channel is a module in the second communication system that differs from the third radio frequency channel. The fifth terminal of the first switching component is coupled to the fourth radio frequency channel. Thus, the radio frequency channel can support antenna multiplexing switching on two or more links in different systems.

[0023] Optionally, the first communication system is a cellular communication system, and the second communication system is a satellite communication system. The operating frequency of the first antenna includes at least a portion of the frequency corresponding to the cellular communication, and the operating frequency of the first antenna also includes at least a portion of the frequency corresponding to the satellite communication.

[0024] Optionally, the third radio frequency channel is the transmit TX radio frequency channel in the satellite communication system, and the fourth radio frequency channel is the receive RX radio frequency channel in the satellite communication system. Alternatively, the third radio frequency channel is the RX radio frequency channel in the satellite communication system, and the fourth radio frequency channel is the receive TX radio frequency channel in the satellite communication system.

[0025] Optionally, the at least one switching component further includes a second switching component and a third switching component. The electronic device is also configured with a second antenna, a third antenna, and a fourth antenna. The operating frequencies of the second antenna, the third antenna, and the fourth antenna each include at least a portion of cellular communication frequencies. The ports of the second switching component include a first terminal, a second terminal, a third terminal, a fourth terminal, a fifth terminal, and a sixth terminal. The second switching component can be configured such that any one of its first, second, and third terminals is connected to any one of its fourth, fifth, and sixth terminals. The ports of the third switching component include a first terminal, a second terminal, a third terminal, a fourth terminal, a fifth terminal, and a sixth terminal. The third switching component can be configured such that any one of its first, second, and third terminals is connected to any one of its fourth, fifth, and sixth terminals. The radio frequency circuit further includes a fifth radio frequency channel and a sixth radio frequency channel. The first radio frequency channel, the second radio frequency channel, the fifth radio frequency channel, and the sixth radio frequency channel each correspond to the first communication system.

[0026] Optionally, the second terminal of the first switching component is coupled to the third terminal of the second switching component, and the third terminal of the first switching component is coupled to the second terminal of the third switching component. The first terminal of the second switching component is coupled to the second antenna, the second terminal of the second switching component is coupled to the third antenna, the fourth terminal of the second switching component is coupled to the first radio frequency channel, the fifth terminal of the second switching component is coupled to the second radio frequency channel, and the sixth terminal of the second switching component is coupled to the first terminal of the third switching component. The third terminal of the third switching component is coupled to the third antenna, the fifth terminal of the third switching component is coupled to the fifth radio frequency channel, and the sixth terminal of the third switching component is coupled to the sixth radio frequency channel.

[0027] This provides a specific example in which the first communication system can be a cellular communication system. This cellular communication system may include four antennas and at least four radio frequency links with TAS switching capability. The second communication system can be a satellite communication system. Based on this implementation, at least one cellular antenna can be multiplexed for either TX signal transmission or RX signal reception in satellite communication.

[0028] Optionally, the baseband module in the first communication system of the electronic device is also used to control the conduction state of the second switch assembly and the third switch assembly.

[0029] Optionally, the first radio frequency channel, the second radio frequency channel, the fifth radio frequency channel, and the sixth radio frequency channel correspond to at least one of the following: a cellular receiver RX module, a cellular transmitter / main receiver TX / PRX radio frequency channel.

[0030] Optionally, the first switching assembly includes a single-pole four-throw SP4T switch.

[0031] In a second aspect, an electronic device is provided, which includes radio frequency circuitry as provided in the first aspect and any possible design thereof.

[0032] It is understood that the solution provided by the second aspect of this application can be respectively associated with the first aspect and any of its possible designs, and therefore the beneficial effects can be achieved are similar, which will not be repeated here.

[0050] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0051] Electronic devices can be equipped with one or more communication systems to achieve wireless communication functions.

[0052] For example, let's take a mobile phone as an example. (Reference) Figure 1 This provides a logical schematic of a communication system.

[0053] like Figure 1 As shown, the communication system may include an antenna, a radio frequency (RF) module, and a baseband module. In this embodiment, the RF module may include a collection of electronic components and peripheral circuits for performing RF processing. For example, the electronic components may include at least one of the following: an RF filter, a power amplifier (PA), a low-noise power amplifier (LNA), etc.

[0054] The antenna is coupled to one end of the radio frequency module; the other end of the radio frequency module is coupled to the baseband module.

[0055] In the embodiments of this application, coupling can be used to represent a connection method of electrical connection. Specific implementations may include direct electrical connection, indirect connection through electronic devices, and coupled electrical connection, etc. Through coupling, signal transmission between two modules can be achieved. For example, direct electrical connection may include: connecting corresponding ports of two components through a signal connection line to achieve electrical signal transmission between the two components.

[0056] Taking the signal reception (RX) scenario as an example, when this communication system is working, the antenna can receive electromagnetic waves in space and generate a corresponding RX signal (or RX electrical signal). This RX signal can be an analog signal.

[0057] The RX signal can be transmitted to an RF module for RF processing. For example, the RF processing of the RX signal may include amplification, filtering, noise reduction, etc.

[0058] The RX signal, after radio frequency processing, can be converted into a digital signal and transmitted to the baseband module for digital analysis and other processing. Thus, electronic devices can acquire the communication information carried in the electromagnetic waves and achieve signal reception.

[0059] Corresponding to the signal reception scenario, electronic devices can also radiate signals (TX) through this communication system. For example, the baseband module can load the communication information to be transmitted into a digital signal. This digital signal can be converted into an analog signal, which is then processed by the radio frequency (RF) module. The RF-processed analog signal can be fed into an antenna, causing the antenna to convert the analog signal into electromagnetic waves and radiate it outwards.

[0060] In some cases, electronic devices can support wireless communication functions from multiple different systems. For example, the wireless communication functions supported by an electronic device may include at least one of the following: cellular communication, GPS / Wi-Fi communication, satellite communication, and ultra-wideband (UWB) communication. In the embodiments of this application, satellite communication may include satellite communication based on the Tiantong system, and / or satellite communication may include satellite communication based on the Beidou system.

[0061] Correspondingly, electronic devices can be configured with corresponding communication systems for different wireless communication functions.

[0062] For example, electronic devices can have cellular communication functions and be configured with corresponding cellular communication systems; electronic devices can have Bluetooth / Wi-Fi communication functions and be configured with corresponding GPS / Wi-Fi communication systems; electronic devices can have satellite communication functions and be configured with corresponding satellite communication systems.

[0063] For any communication system, it can have the following characteristics: Figure 1 The diagram illustrates the components of a communication system. In a practical implementation, the number of components in the communication system (such as antennas, radio frequency modules, etc.) can be one or more.

[0064] For example, refer to Figure 2 This is a schematic diagram of the logical composition of various components of a communication system in an electronic device.

[0065] In this application, the antenna in the communication system may include one or more. For example... Figure 2 In the example, antennas may include antenna A0, antenna A1, antenna A2, antenna A3, antenna A4, etc. The operating frequency bands of each antenna may be the same, partially the same, or completely different. The collection of operating frequency bands of all antennas can collectively cover the frequency bands required for the various wireless communication functions of the electronic device.

[0066] In such Figure 2 The example also provides a schematic diagram of antenna logic composition based on antenna function. For example, antennas in electronic devices may include: primary multiple input multiple output (TX / PRX) antennas, diversity multiple input multiple output (DRX) antennas, primary multiple input multiple output (PMIMO) antennas, secondary multiple input multiple output (DMIMO) antennas, etc. PMIMO antennas are abbreviated as PM antennas, and DMIMO antennas are abbreviated as DM antennas.

[0067] It is understandable that in the above example, the operating frequency band of any one of the TX / PRX antenna, DRX antenna, PM antenna, and DM antenna can be included in the 450MHz-3GHz cellular communication frequency band. These four antennas can cooperate with each other to enable the electronic device to transmit and receive signals during cellular communication.

[0068] It should be noted that in this example, the names of the TX / PRX antenna, DRX antenna, PM antenna, and DM antenna are merely examples and do not constitute any limitation on the configuration of antennas in an electronic device. In other embodiments, the names of the antennas used for cellular communication in the electronic device may differ from the examples above; in other embodiments, the number of antennas used for cellular communication in the electronic device may be more or less. This application does not impose any limitations on this.

[0069] In some cases, such as when electronic devices have satellite communication capabilities, the antenna in the electronic device can also include a satellite antenna.

[0070] Take an electronic device with GPS / Wi-Fi communication capabilities as an example. Therefore, the antenna in the electronic device can also include a GPS / Wi-Fi antenna.

[0071] Other similar cases will not be elaborated upon further.

[0072] It should be noted that different communication systems may require different operating frequency bands, or these bands may overlap at least partially. For communication systems whose operating frequency bands overlap or at least partially overlap, antennas may be shared or partially shared for signal transmission and reception.

[0073] For example, the operating frequency band of a cellular communication system can include that of a satellite communication system. This allows electronic devices to be equipped with cellular antennas (such as TX / PRX antennas, DRX antennas, PM antennas, DM antennas, etc.). Electronic devices may not need to additionally configure satellite antennas. When satellite communication is required, any one or more of the cellular antennas can be reused for signal transmission and reception.

[0074] In other embodiments of this application, for communication systems with two non-overlapping operating frequency bands, signal transmission and reception can also be performed by using multiplexed antennas when the corresponding two operating frequency bands are very close.

[0075] For example, when the two operating frequency bands are very close, the relative bandwidth corresponding to the frequency interval between the two operating frequency bands is not less than 5%.

[0076] In some embodiments, the operating frequency band of the first communication system includes a second frequency, such as 1 GHz. The operating frequency band of the second communication system includes a third frequency, such as 1.05 GHz. Taking the second frequency as the maximum frequency in the operating frequency band of the first communication system and the third frequency as the minimum frequency in the operating frequency band of the second communication system as an example, the operating frequency bands of the two communication systems do not overlap. The spacing bandwidth between the two operating frequency bands is 1.05 GHz - 1 GHz = 0.05 GHz. The relative bandwidth of the spacing bandwidth is 0.05 GHz / 1.05 GHz = 4.7%. In this case, since the relative bandwidth is less than 5%, the operating frequency bands of the first and second communication systems are very close. Therefore, signal transmission and reception of the two communication systems can be achieved by using a multiplexed antenna.

[0077] In some implementations, the operating frequency of the multiplexed antenna may include portions of the interval frequency band. For example, the multiplexed antenna may be a first antenna. The operating frequency band of the first antenna may include the interval frequency bands in the example above (e.g., 1 GHz - 1.05 GHz).

[0078] In this example, the radio frequency (RF) module may include one or more RF modules. These RF modules can provide RF processing functions for signal reception and / or signal transmission in different communication systems, or within the same communication system. In some embodiments, one RF module may correspond to one RF channel. In other embodiments, the RF channel may further include an RF module and related peripheral circuitry.

[0079] In some embodiments, the radio frequency module may include a first radio frequency module, a second radio frequency module, etc.

[0080] In other embodiments, the radio frequency module may include a cellular TRX module and a cellular RX module. The cellular TRX module can be used for radio frequency processing of TX signals and / or RX signals in cellular communication. The cellular RX module can be used for radio frequency processing of RX signals in cellular communication. In some implementations, the cellular TRX module may correspond to a cellular TRX radio frequency channel, or simply be referred to as a cellular TRX channel. The cellular RX module corresponds to a cellular RX radio frequency channel, or simply be referred to as a cellular RX channel.

[0081] The configuration of each RF module in the above-described RF module is merely an example. In other implementations, the number or type of RF modules in the RF module may differ from the examples above. For instance, an electronic device may be configured with two or more cellular TRX modules. Similarly, an electronic device may be configured with two or more cellular RX modules, etc. This application does not impose any limitations on these aspects.

[0082] In such Figure 2 In the example, the radio frequency module may also include a satellite TX module and a satellite RX module. The satellite TX module is used for radio frequency processing of the TX signal in satellite communication. The satellite RX module is used for radio frequency processing of the RX signal in satellite communication. In some implementations, the satellite TX module may correspond to a satellite TX radio frequency channel, or simply be referred to as a satellite TX channel. The satellite RX module may correspond to a satellite RX radio frequency channel, or simply be referred to as a satellite RX channel.

[0083] In other embodiments, the electronic device may also include other radio frequency (RF) modules to support the RF processing capabilities of other communication systems. For example, the electronic device may include a GPS module to support RF processing capabilities for GPS communication. Similarly, the electronic device may include a Wi-Fi module to support RF processing capabilities for Wi-Fi communication. Furthermore, the electronic device may include a UWB module to support RF processing capabilities for UWB communication.

[0084] Similarly, in other implementations, a GPS module can correspond to a GPS RF channel, simply referred to as the GPS channel. A Wi-Fi module can correspond to a Wi-Fi RF channel, simply referred to as the Wi-Fi channel. A UWB module can correspond to a UWB RF channel, simply referred to as the UWB channel.

[0085] In practice, the number and types of radio frequency modules in electronic devices can be flexibly set according to the wireless communication functions that need to be supported.

[0086] like Figure 2 As shown, the baseband module used for digital processing may also include one or more modules.

[0087] In some embodiments, the baseband module may include a first baseband module, a second baseband module, etc.

[0088] In other embodiments, the baseband module may include a cellular baseband module, a satellite baseband module, etc. The cellular baseband module can perform digital signal processing in cellular communication. Similarly, the satellite baseband module can perform corresponding digital signal processing in satellite communication.

[0089] It should be noted that, in some embodiments of this application, the baseband module can also be used to control the operating state of other electronic components via control commands. For example, a cellular baseband module can control one or more switches to operate in different on / off states. Similarly, a satellite baseband module can control one or more switches to operate in different on / off states.

[0090] In other embodiments, the control of the electronic components may be performed by components other than the baseband modules described above. For example, the central processing unit (CPU) in an electronic device can generate control commands to control the operating state of electronic components (such as switches) in the communication system. Similarly, the modem in an electronic device can generate control commands to control the operating state of electronic components (such as switches) in the communication system. In different implementations, the modem may be integrated with or separated from the baseband module.

[0091] The following combination Figure 1 and Figure 2 The description provides examples of communication system configurations used to implement various communications in electronic devices.

[0092] refer to Figure 3 This is a schematic diagram of a circuit logic connection. Figure 3 The logical connections shown can be set up in a cellular communication system to support the cellular communication functions of electronic devices.

[0093] In this example, the antenna may include antenna A0, antenna A1, antenna A2, and antenna A3.

[0094] In some embodiments, the operating frequency bands of antennas A0 to A3 may respectively cover at least a portion of the cellular communication frequency bands. For example, the operating frequency band of antenna A0 may include 450MHz to 3GHz.

[0095] In some implementations, antenna A0 can correspond to a TX / PRX antenna, antenna A1 can correspond to a DRX antenna, antenna A2 can correspond to a PM antenna, and antenna A3 can correspond to a DM antenna.

[0096] In this example, the radio frequency module may include: a cellular TRX module, a cellular RX module 1, a cellular RX module 2, and a cellular RX module 3.

[0097] In some implementations, the cellular TRX module can correspond to the TX / PRX module (or TX / PRX RF module) corresponding to the antenna, the cellular RX module 1 can correspond to the DRX module, the cellular RX module 2 can correspond to the PM module, and the cellular RX module 3 can correspond to the DM module.

[0098] The cellular TRX module can be used for radio frequency processing in signal transmission and / or signal reception scenarios. Cellular RX modules 1 to 3 can be used for radio frequency processing in signal reception scenarios, respectively. In different implementations, the processing frequency bands of cellular RX modules 1, 2, and 3 can be the same, at least partially different, or completely different. This application does not impose any limitations on this.

[0099] Combination Figure 2 The explanation in the text is as follows: Figure 3 In the example, each cellular module can be coupled to the corresponding port of the cellular baseband module to facilitate signal transmission between the radio frequency domain and the digital domain.

[0100] like Figure 3 As shown, based on the above components, the connection relationship between the antenna and each RF module can include:

[0101] Antenna A0 can be coupled to the cellular TRX module; antenna A1 can be coupled to the cellular RX1 module; antenna A2 can be coupled to the cellular RX2 module; antenna A3 can be coupled to the cellular RX3 module.

[0102] In the following description, the above connection relationship may also be referred to as the default connection relationship.

[0103] It is understandable that the default connection may not provide optimal communication quality when electronic devices are used in different scenarios (such as one-handed holding, two-handed holding, or using a case).

[0104] In this way, a switching component can be installed between the antenna and each cellular module. This switching component can operate in different on / off states, thereby controlling the switching of the logical connection between the antenna and the cellular module. Consequently, electronic devices can achieve better communication quality in different usage scenarios by switching the connection between the antenna and the cellular module.

[0105] For example, such as Figure 3 As shown, in this example, at least switch 1 and switch 2 can be provided between the antenna and the radio frequency module.

[0106] In some embodiments, switch 1 and switch 2 may have the same conducting capability. For example... Figure 3 As shown, switch 1 / switch 2 can be equipped with at least 6 signal transmission ports, such as port 1 to port 6. Switch 1 / switch 2 can also be equipped with a control terminal.

[0107] Among them, any one of ports 1, 2, and 3 of switch 1 / switch 2 can be connected to any one of ports 4, 5, and 6. The control terminal can be used to receive control signals.

[0108] Therefore, when switch 1 / switch 2 is operating, control signals can be received through the control terminal. Depending on the type of control signal, switch 1 / switch 2 can control the conduction state of ports 1, 2, and 3, as well as ports 5-6. In this example, the different conduction states of the ports correspond to the switches operating in different conduction states.

[0109] In such Figure 3 In the example, the connection relationship of switch 1 may include: port 1 of switch 1 is coupled to antenna A2; port 2 of switch 1 is coupled to antenna A3; port 3 of switch 1 is coupled to port 4 of switch 2; port 4 of switch 1 is coupled to cellular RX module 2; port 5 of switch 1 is coupled to cellular RX module 3; and port 6 of switch 1 is coupled to port 1 of switch 2.

[0110] The connection relationships of switch 2 may include: port 1 of switch 2 is coupled to port 6 of switch 1; port 2 of switch 2 is coupled to antenna A0; port 3 of switch 2 is coupled to antenna A1; port 4 of switch 2 is coupled to port 3 of switch 1; port 5 of switch 2 is coupled to the cellular TRX module; and port 6 of switch 2 is coupled to the cellular RX module 1.

[0111] Thus, when the communication system is operating in the default state, the electronic device can control the connection of port 1 and port 4 of switch 1, and the connection of port 2 and port 5 of switch 1; the electronic device can control the connection of port 2 and port 5 of switch 2, and the connection of port 3 and port 6 of switch 1.

[0112] Therefore, the signal transmission link of antenna A0 may include: antenna A0 - switch 2 - cellular TRX module - cellular baseband module.

[0113] The signal transmission link of antenna A1 may include: antenna A0 - switch 2 - cellular RX module 1 - cellular baseband module.

[0114] The signal transmission link of antenna A2 may include: antenna A0 - switch 1 - cellular RX module 2 - cellular baseband module.

[0115] The signal transmission link of antenna A3 may include: antenna A0 - switch 1 - cellular RX module 3 - cellular baseband module.

[0116] As explained above, the electronic device can also control switch 1 and / or switch 2 to operate in other conduction states via control signals to obtain better communication quality. In this application, the switch 1 and switch 2 operate in the default conduction state, corresponding to the communication system being in the default state. When switch 1 and / or switch 2 operate in other conduction states besides the default state, it can be referred to as the switch components operating in a switching (TAS) state, corresponding to the communication system being in the TAS state.

[0117] For example, in some embodiments, the electronic device can control port 4 of switch 1 to be connected to port 3 of switch 1, and control port 4 of switch 2 to be connected to port 2 of switch 2. In this way, the logical connection between cellular RX module 2 and antenna A0 can be achieved.

[0118] Therefore, the signal received by antenna A0 can be transmitted to cellular RX module 2 for radio frequency processing. Taking antenna A0 as a TX / PRX antenna and cellular RX module 2 as a PM module as an example, the switching scheme in this example allows signal reception on the PM link to be achieved through the TX / PRX antenna.

[0119] In the example above, the RF module coupled to switch 1 can transmit and receive signals through the antenna coupled to switch 2 via port 3 of switch 1 and port 4 of switch 2.

[0120] Similarly, in other embodiments, the RF module coupled to switch 2 can transmit and receive signals through the antenna coupled to switch 1 via port 6 of switch 1 and port 1 of switch 2.

[0121] For example, the electronic device can control port 1 of switch 1 to be connected to port 6 of switch 1, and control port 1 of switch 2 to be connected to port 5 of switch 2. In this way, the logical connection between the cellular TRX module and antenna A2 can be achieved.

[0122] Therefore, signal transmission and reception corresponding to the cellular TRX module can be performed through antenna A2. Taking antenna A2 as a DM antenna and the cellular TRX module as a TX / PRX module as an example, the switching scheme in this example can realize signal transmission and reception on the TX / PRX link through the DM antenna.

[0123] Understandably, the above example provides a concrete example of how the switching of two switches can couple and connect the cellular module of one switch to the antenna of another. Based on a similar mechanism, the electronic device can also control switches 1 and 2, using ports 3 and 6 of switch 1 and ports 1 and 4 of switch 2 to switch the signal between the cellular modules and antennas of different switches.

[0124] In other embodiments, the electronic device can also control switch 1 or switch 2 to be in different conduction states, so that the antenna of the same switch can be connected to different cellular modules.

[0125] For example, an electronic device can control port 1 of switch 1 to be connected to port 5 of switch 1, so that antenna A2 can be coupled to cellular RX module 3. Thus, signal reception on cellular RX module 3 (e.g., DM link) is achieved through antenna A2 (e.g., PM antenna).

[0126] Other similar cases will not be elaborated upon further.

[0127] It should be noted that, in cases such as Figure 3 The illustrated scheme is based on the example where both switch 1 and switch 2 have 6 signal transmission ports. In some implementations, the switch components corresponding to switch 1 and / or switch 2 can be 3P3T switches.

[0128] In other implementations, in this case... Figure 3 In the communication system shown, switch 1 and / or switch 2 can also be replaced with switch components having a different number of signal transmission ports, or more or fewer switch components can be provided in the communication system. This application embodiment does not impose any limitations on this.

[0129] Thus, in such Figure 3 In the implementation of the scheme shown, a switch component is added between the antenna and the radio frequency module to realize the switching between the default state and the TAS state in cellular communication.

[0130] refer to Figure 4 This is a schematic diagram of the logic connection of another type of circuit. Figure 4 The logical connections shown can be used to support satellite communication functions of electronic devices.

[0131] In this example, the antenna in the communication system may include antenna A4. In some embodiments, the operating frequency band of antenna A4 may cover the frequency band of satellite communication. For example, the frequency band of satellite communication may include at least one of the following: the frequency band corresponding to Tiantong satellite, the frequency band corresponding to Beidou satellite, etc.

[0132] In this example, the radio frequency modules that the communication system may include: a satellite TX module and a satellite RX module.

[0133] The cellular TX module can be used for radio frequency processing in satellite communication signal transmission scenarios. The cellular RX module can be used for radio frequency processing in satellite communication signal reception scenarios.

[0134] like Figure 4 As shown, a switching assembly can also be provided between the antenna and the radio frequency module. For example, the switching assembly may include switch 3.

[0135] In this example, switch 3 may include at least three signal transmission ports. For example, port 1 of switch 3, port 2 of switch 3, and port 3 of switch 3.

[0136] The switch 3 can also be configured with a control terminal to receive control commands from electronic devices and, according to the control commands, connect port 1 and port 2, or connect port 1 and port 3.

[0137] In some embodiments, switch 3 can be implemented using an SPDT switch. In other embodiments, switch 3 can also be implemented using a switch with more ports (such as a single-pole four-throw SP4T).

[0138] like Figure 4 As shown, antenna A4 can be coupled to port 1 of switch 3, port 2 of switch 3 can be coupled to the satellite TX module, and port 3 of switch 3 can be coupled to the satellite RX module. The other ends of the satellite TX module and the satellite RX module are both coupled to the corresponding ports of the satellite baseband module.

[0139] Thus, based on such Figure 4 The logical connections are shown below. Taking satellite signal transmission as an example, switch 3 can, under the control of the electronic device, connect ports 1 and 2. Thus, the satellite TX signal can be transmitted via the satellite baseband module - satellite TX module - switch 3 - antenna A4. Taking satellite signal reception as an example, switch 3 can, under the control of the electronic device, connect ports 1 and 3. Thus, the satellite RX signal can be received via antenna A4 - switch 3 - satellite RX module - satellite baseband module.

[0140] Understandable, Figure 3 as well as Figure 4 Examples of logical connections for communication systems supporting cellular and satellite communications are provided respectively. When the electronic device also supports other wireless communications (such as Wi-Fi, GPS, etc.), the corresponding communication system can also be configured in the electronic device.

[0141] In such Figure 3 as well as Figure 4In the description, the switching components (such as switch 1, switch 2 and switch 3) can receive control commands from electronic devices through control ports, so as to operate in the corresponding conduction state according to the control commands.

[0142] In some embodiments, the control command may be issued by the baseband module (or modem) corresponding to the communication system.

[0143] Taking the control command of the switch issued through the baseband module as an example, in some implementations, the switch is a general-purpose input / output (GPIO) switch, and the corresponding control command can be to control the GPIO signal. In other implementations, the switch is a Mobile Industry Processor Interface (MIPI) switch, and the corresponding control command can be to control the MIPI signal.

[0144] refer to Figure 5 , for example Figure 3 as well as Figure 4 The logic shown illustrates the control connection logic for each switch component.

[0145] like Figure 5 As shown, switches 1 and 2 in the cellular communication system can be controlled by a cellular baseband module. The cellular baseband module can be configured with control port 1 and control port 2. Control port 1 can be coupled to the control terminal of switch 1, and control port 2 can be coupled to the control port of switch 2. In this way, the cellular baseband module can send corresponding control commands to switch 1 through control port 1 to make switch 1 operate in the corresponding ON state. Similarly, the cellular baseband module can send corresponding control commands to switch 2 through control port 2 to make switch 2 operate in the corresponding ON state.

[0146] In such Figure 5 The example also provides control connection logic for a satellite communication system.

[0147] For example, switch 3 in a satellite communication system can be controlled by a satellite baseband module. The satellite baseband module can be configured with a control port 3. Control port 3 can be coupled to the control terminal of switch 3. In this way, the satellite baseband module can send corresponding control commands to switch 3 through control port 3, causing switch 3 to operate in the corresponding on state.

[0148] like Figure 5 As shown, the control logic of the switching components in different systems can be implemented by the baseband module of their respective systems.

[0149] As electronic devices evolve, the space available for antennas is constantly being reduced. Therefore, for antennas in different systems operating at overlapping frequencies, antenna reuse can be used to ensure communication between systems while reducing the number of antennas required.

[0150] For example, consider cellular communication systems and satellite communication systems in electronic devices. In a cellular communication system, the operating frequency band of the antenna may include the operating frequency band required for satellite communication. Thus, in some implementations, when conducting satellite communication, a switching component can be used to switch the cellular communication on an antenna whose operating frequency band covers the satellite communication frequency band. Correspondingly, the cellular communication on the cellular antenna used for satellite communication can be switched to other cellular antennas (such as those configured as follows). Figure 4 The TAS switching mechanism shown can be switched to another cellular antenna to continue communication; or, if the cellular antenna is not conducting cellular communication, the cellular antenna can be used for satellite communication.

[0151] refer to Figure 6 This is another example of the logical connection of a circuit.

[0152] In this example, a cellular antenna comprising antennas A0 to A3 is used. At least one of the cellular antennas operates in a frequency band that covers satellite communication bands. For example, the operating frequency band of antenna A0 can cover satellite communication bands.

[0153] In this way, when antenna A0 is idle, the electronic equipment can control antenna A0 to couple with the satellite TX module and / or the satellite RX module to enable satellite communication through antenna A0. Alternatively, when antenna A0 is conducting cellular communication, if satellite communication is required, the electronic equipment can switch the cellular communication signal on antenna A0 to another cellular antenna to continue, thus using antenna A0 for cellular communication.

[0154] like Figure 6 As shown, to achieve the above functions, the communication system can be configured with at least three switching components. These switching components can be configured between the antenna and the radio frequency module. For example, the at least three switching components may include: switch 1, switch 2, and switch 3.

[0155] In some implementations, switch 1 and switch 2 may include at least six signal transmission ports, as well as a control terminal. For specific implementation details of switch 1 and switch 2, please refer to [example missing]. Figure 3 The explanation in the document.

[0156] Furthermore, switch 4 may include at least four signal transmission ports and a control terminal. For example, switch 4 may include port 1, port 2, port 3, and port 4. Port 1 may be configured to be connected to any one of port 2, port 3, and port 4. In this implementation, switch 4 may include an SP3T switch.

[0157] In other implementations, switch 4 may include more signal transmission ports. For example, switch 4 may include port 1, port 2, port 3, port 4, and port 5. Port 1 may be configured to be connected to any one of port 2, port 3, port 4, and port 5. In this implementation, switch 4 may include an SP4T switch.

[0158] In the following example, switch 4, which includes 4 signal transmission ports, is used as an example.

[0159] like Figure 6 As shown, the logical connections of this communication system may include:

[0160] Port 1 of switch 1 is coupled to antenna A2, port 2 of switch 1 is coupled to antenna A3, port 3 of switch 1 is coupled to port 4 of switch 2, port 4 of switch 1 is coupled to cellular RX module 2, port 5 of switch 1 is coupled to cellular RX module 3, and port 6 of switch 1 is coupled to port 1 of switch 2.

[0161] Port 2 of switch 2 is coupled to port 2 of switch 4, port 3 of switch 2 is coupled to antenna A1, port 5 of switch 2 is coupled to the cellular TRX module, and port 6 of switch 2 is coupled to the cellular RX module 1.

[0162] Port 1 of switch 4 is coupled to antenna A0, port 3 of switch 4 is coupled to satellite TX module, and port 4 of switch 4 is coupled to satellite RX module.

[0163] In addition, each cellular module is coupled to the cellular baseband module, and each satellite module is coupled to the satellite baseband module.

[0164] Thus, through such Figure 6 The communication system shown uses switch 4 to connect the satellite module in the radio frequency module to the cellular handover logic, thus achieving... Figure 3 and Figure 4 The integration of the illustrated scheme. Furthermore, this... Figure 6 The proposed solution also enables the reuse of cellular antennas for satellite communication.

[0165] For example, consider a communication system in its default state.

[0166] With switch 1 connected to port 4, antenna A2 is coupled to cellular RX module 2. Antenna A2 is used for signal transmission and reception of the communication link (such as PM link) corresponding to cellular RX module 2.

[0167] Switch 1's ports 2 and 5 are connected, and antenna A3 is coupled to cellular RX module 3. Antenna A3 is used to receive signals from the communication link (such as a DM link) corresponding to cellular RX module 3.

[0168] Switch 4's ports 1 and 2 are connected, and switch 2's ports 2 and 5 are connected. Antenna A0 is coupled to the cellular TRX module. Antenna A0 is used for signal transmission and reception on the communication link corresponding to the cellular TRX module (such as the TX / PRX link).

[0169] Switch 2's ports 3 and 6 are connected, and antenna A1 is coupled to cellular RX module 1. Antenna A1 is used for signal transmission and reception of the communication link (such as DRX link) corresponding to cellular RX module 1.

[0170] Electronic devices can also control the communication system to be in TAS state.

[0171] For example, in some embodiments, the electronic device can control switch 1 and / or switch 2 to be in different on states, thereby enabling switching between different cellular antennas and different radio frequency modules. For specific implementation details, please refer to... Figure 3 The explanation in the document.

[0172] In other embodiments, the electronic device may also control switch 1 and / or switch 2 and / or switch 4 to be in a conducting state different from the default state, so as to achieve the purpose of satellite communication through cellular antenna.

[0173] Take satellite communication using electronic control antenna A0 as an example.

[0174] The electronic device can control the connection between ports 1 and 3 of switch 4. In this way, antenna A0 can be coupled to the satellite TX module via switch 4, thus achieving the purpose of transmitting satellite TX signals through antenna A0.

[0175] The electronic device can control the connection between port 1 and port 4 of switch 4. In this way, antenna A0 can be coupled to the satellite RX module via switch 4, thus achieving the purpose of receiving satellite RX signals through antenna A0.

[0176] refer to Figure 7 This shows, as Figure 6 The communication system shown illustrates the control connection logic for each switching component. Continuing with the example of an electronic device controlling a corresponding switching component in the system via a baseband module,...

[0177] like Figure 7 As shown, similar to Figure 5 The control connection logic is shown below. In this... Figure 6 In the example, the cellular baseband module can be used to control the on / off state of switches 1 and 2. For instance, control port 1 of the cellular baseband module is coupled to the control terminal of switch 1, and control port 2 of the cellular baseband module is coupled to the control terminal of switch 2. Thus, the cellular baseband module can send control commands to switch 1 through control port 1 to make switch 1 operate in the default state or the TAS state. Similarly, the cellular baseband module can send control commands to switch 2 through control port 2 to make switch 2 operate in the default state or the TAS state.

[0178] The control port 3 of the satellite communication module in the electronic device can be coupled to the control terminal of the switch 4 to control the conduction state of the switch 4. In this way, the satellite baseband module can send control commands to the switch 4 through the control port 3, so that the switch 4 can operate in different states.

[0179] Therefore, the satellite baseband module can control switch 4, and the on / off state of switch 4 does not require the involvement of the cellular baseband module. Correspondingly, the control of switches 1 and 2 is handled by the cellular baseband module, and the satellite baseband module does not need to have a direct communication connection with switches 1 and 2.

[0180] In some implementations, the satellite baseband module can control the switching of port 1 and port 2 of switch 4 to enable antenna A0 to be coupled to the cellular TRX module, thereby allowing antenna A0 to be used for cellular communication corresponding to the cellular TRX module.

[0181] In other implementations, the satellite baseband module can control port 1 of switch 4 to be connected to port 3 or port 4 so that antenna A0 is coupled to the satellite TX module or the satellite RX module, thereby antenna A0 can be used for signal transmission and reception in satellite communication.

[0182] Combination Figure 6 and Figure 7 Examples in, such as Figure 6 In the communication system shown, when the electronic device controls the switching of cellular communication from antenna A0 to antenna A3 via TAS, the satellite baseband module can control switch 4 to maintain the conducting state of ports 1 and 2. Therefore, the cellular baseband module can, based on... Figure 3 A similar scheme is implemented by controlling switch 1 and switch 2 to be in different conduction states, thereby enabling the switching between the cellular antenna and each cellular module.

[0183] For example, in the default state, during TRX communication via antenna A0, the corresponding link consists of: antenna A0 - switch 4 - switch 2 - cellular TRX module.

[0184] During the communication (such as PM communication) between the cellular RX module 2 and the antenna A2, the link consists of: antenna A2 - switch 1 - cellular RX module 2.

[0185] In TAS mode, taking PM communication via antenna A0 as an example, the satellite baseband module can control the conduction of ports 1 and 2 of switch 4, the cellular baseband module can control the conduction of ports 3 and 4 of switch 1, and the cellular baseband module can control the conduction of ports 2 and 4 of switch 2. Thus, the PM link consists of: antenna A0 - switch 4 - switch 2 - switch 1 - cellular RX module 2.

[0186] The above Figure 6 The communication system shown is illustrated using a combination of cellular and satellite communication systems, with cellular antenna multiplexing as an example for satellite communication. In other embodiments, other communication systems can be combined to achieve reasonable multiplexing and switching between different systems.

[0187] For example, refer to Figure 8 This is a schematic diagram of the logic connection of another circuit. In this example, the antenna in the electronic device may include antenna A5. The operating frequency band of antenna A5 may include at least a portion of the sub-6 GHz operating frequency band. The sub-6 GHz operating frequency band may be 450 MHz-6 GHz. In some implementations, the operating frequency band of antenna A5 may include at least one of the following: cellular operating frequency band, GPS frequency band, 2.4 GHz / 5 GHz Wi-Fi frequency band, satellite communication frequency band, etc.

[0188] In such Figure 8 In the example, antenna A5 can be used for cellular communication, GPS communication, and satellite communication.

[0189] like Figure 8 As shown, the communication system may include switch 4 for coupling antenna A5 and radio frequency modules of different systems. This switch 4 can be referenced as follows: Figure 6 The example is shown below. The communication system may also include a combiner. One side of the combiner (e.g., the first side) has one port, and the other side (e.g., the second side) has at least two ports. In some implementations, the combiner can be used to combine signals from two or more ports on the second side into a single signal, which is then output from the first side. In other implementations, the combiner can be used to split a signal received on the first side into two or more signals, which are then output separately from the ports on the second side.

[0190] The logical connections of the communication system provided in this example may include: port 1 of switch 4 coupled to antenna A5; port 2 of switch 4 coupled to a port on the first side of the combiner; port 3 of switch 4 coupled to a satellite TX module; and port 4 of switch 4 coupled to a satellite RX module. Of at least two ports on the second side of the combiner, one port is coupled to a cellular TRX module, and the other port is coupled to a GPS module. The GPS module is used for radio frequency processing of GPS signals. Furthermore, the cellular TRX module may also be coupled to a cellular baseband module, the GPS module may also be coupled to a GPS baseband module, and the satellite TX and satellite RX modules may also be coupled to a satellite baseband module.

[0191] Thus, in this way Figure 8 In the scheme shown, the electronic device can control switch 4 to be in different conduction states, enabling antenna A5 to communicate with different systems.

[0192] For example, the electronic device can control the switching device 4 to connect ports 1 and 2, enabling antenna A5 to transmit and receive signals for cellular or GPS communication. The electronic device can control the switching device 4 to connect ports 1 and 3, enabling antenna A5 to transmit signals for satellite TX communication. The electronic device can control the switching device 4 to connect ports 1 and 4, enabling antenna A5 to receive signals for satellite RX communication.

[0193] refer to Figure 9 The diagram below illustrates the logic of another circuit. In this example, the antenna in the electronic device may include antenna A5 and antenna A6. The operating frequency band of antenna A5 and / or antenna A6 may include at least a portion of the sub-6 GHz operating frequency band. For example, the operating frequency band of antenna A5 may cover the GPS band, at least a portion of the sub-6 GHz band, the TX band for satellite communication, etc. The operating frequency band of antenna A6 may cover the 2.4 GHz Wi-Fi band, at least a portion of the sub-6 GHz band, the RX band for satellite communication, etc.

[0194] In such Figure 9 In the example, antenna A5 can be used for cellular communication, GPS communication, or satellite TX communication. Antenna A6 can be used for cellular communication, 2.4G Wi-Fi communication, or satellite RX communication.

[0195] Combination Figure 8 The example scheme, in which the logical connection of the communication system provided in this example may include: port 1 of switch 4 is coupled to antenna A5, port 2 of switch 4 is coupled to a port on the first side of the combiner, port 3 of switch 4 is coupled to the satellite TRX module, and port 4 of switch 4 is left floating. Of the at least two ports on the second side of the combiner, one port is coupled to cellular TRX module 1, and the other port is coupled to the GPS module.

[0196] In the link of antenna A6, a switch 3 can be installed. Antenna A6 can be coupled to port 1 of switch 3, port 2 of switch 3 can be coupled to the satellite RX module, and port 3 of switch 3 can be coupled to a port on the first side of another combiner. In the link of antenna A6, of at least two ports on the second side of the combiner, one port is coupled to the cellular TRX module 2, and the other port is coupled to the WIFI module.

[0197] In addition, cellular TRX module 1 and cellular TRX module 2 can also be coupled to cellular baseband module, GPS module can also be coupled to GPS baseband module, satellite TX module and satellite RX module can also be coupled to satellite baseband module, and WI FI module can also be coupled to WI FI baseband module.

[0198] Thus, in this way Figure 9 In the scheme shown, the electronic device can control switches 4 and 3 to be in different conduction states, enabling antenna A5 to communicate with different systems.

[0199] For example, the electronic device can control port 1 and port 2 of switch 4 to be turned on, so that antenna A5 can transmit and receive signals for cellular or GPS communication. The electronic device can control port 1 and port 3 of switch 4 to transmit signals for satellite TX communication. The electronic device can control port 1 and port 2 of switch 3 to receive signals for satellite RX communication. The electronic device can control port 1 and port 3 of switch 3 to transmit and receive signals for cellular or Wi-Fi communication.

[0200] The above Figures 6 to 9 Three communication system schemes are provided, and examples are given to illustrate the specific implementation of antenna multiplexing and switching between different systems by combining at least two wireless communication systems.

[0201] It is understood that in other embodiments, similar to the three circuit schemes described above, other types of communication systems can be configured in the electronic device for antenna switching and multiplexing. The specific implementation of the switching components used in the switching logic can also be flexibly selected according to the actual situation. This application does not impose any limitations on this.

[0202] In this application embodiment, a circuit scheme is also provided, which can realize antenna multiplexing switching when two or more systems are operating. The two or more systems may include at least any two of the following: cellular communication system, satellite communication system, WIFI communication system, GPS communication system, etc.

[0203] For example, consider the implementation of antenna multiplexing switching between a cellular communication system and a satellite communication system using this communication system. In this example, the antenna in the electronic device may include at least one antenna. This at least one antenna may include a first antenna, the operating frequency band of which can simultaneously cover at least a portion of the operating frequency bands of at least two communication systems. Thus, the first antenna can be used to switch between signal transmission and reception of at least two communication systems in different scenarios.

[0204] The following explanation uses two different types of communication systems involved in the scheme, namely cellular communication systems and satellite communication systems, as examples.

[0205] For example, in this circuit scheme, at least one antenna may include antenna A0, antenna A1, antenna A2, and antenna A3. The operating frequency bands of antennas A0 to A3 may all include at least a portion of cellular communication frequency bands. Of the four antennas, at least one may have an operating frequency band covering satellite communication frequency bands. The first antenna may correspond to any one of the four antennas. In the following example, the first antenna corresponds to antenna A0.

[0206] Based on the above examples of cellular communication systems, in some implementations of this example, antenna A0 can be a TX / PRX antenna, antenna A1 can be a DRX antenna, antenna A2 can be a PM antenna, and antenna A3 can be a DM antenna.

[0207] In the actual implementation process, the specific operating frequency band of each antenna can be flexibly set according to actual needs.

[0208] In this circuit design, the radio frequency (RF) modules related to the cellular communication system may include one or more. For example, these one or more RF modules may specifically include: cellular RX RF module 1, cellular RX RF module 2, cellular RX module 3, cellular TRX module, etc. The baseband modules related to the cellular communication system may include cellular baseband modules.

[0209] Radio frequency (RF) modules related to satellite communication systems may include: satellite RX RF modules, satellite TX RF modules, etc. Baseband modules related to satellite communication systems may include satellite baseband modules.

[0210] In this circuit design, one or more switching components can be placed between the antenna and the RF module. These switching components allow the first antenna to switch between transmitting and receiving signals from at least two systems in different scenarios.

[0211] As an example, see reference Figure 10 This is a schematic diagram of the logic connection of another circuit provided in the embodiments of this application.

[0212] like Figure 10 As shown, this circuit scheme may include switch 1, switch 2 and switch 5.

[0213] The specific implementations of switches 1 and 2 can be found in the description above. In this example, switch 5 can be configured with at least 5 signal transmission ports.

[0214] For example, the five signal transmission ports may include: port 1 of switch 5, port 2 of switch 5, port 3 of switch 5, port 4 of switch 5, and port 5 of switch 5. Switch 5 can be configured so that port 1 is open with any of the other four ports.

[0215] The switch 5 may also be provided with at least one control terminal. The switch 5 can receive control commands from electronic devices through the control terminal to perform corresponding circuit opening / closing.

[0216] It should be noted that in some embodiments of this application, the switch 5 can receive control commands from two or more baseband modules through a single control terminal. In this way, the switch 5 can perform on / off control according to a preset priority strategy, using the control command sent by the baseband module with the higher priority. In other embodiments, the switch 5 can be provided with two or more control terminals. Thus, each control terminal of the switch 5 can be coupled to a baseband module. In this way, when multiple control terminals receive control commands, the switch 5 can perform on / off control according to a preset priority strategy, using the control command received by the control terminal with the higher priority.

[0217] like Figure 10 As shown in this example, the connection logic of each component in the circuit scheme may include:

[0218] Antenna A2 is coupled to port 1 of switch 1, port 2 of switch 1 is coupled to antenna A3, port 3 of switch 1 is coupled to port 2 of switch 5, port 4 of switch 1 is coupled to cellular RX module 2, port 5 of switch 1 is coupled to cellular RX module 3, and port 6 of switch 1 is coupled to port 1 of switch 2.

[0219] Port 2 of switch 2 is coupled to port 2 of switch 5, port 3 of switch 2 is coupled to antenna 1, port 5 of switch 2 is coupled to the cellular TRX module, and port 6 of switch 2 is coupled to the cellular RX module 1.

[0220] Port 1 of switch 5 is coupled to antenna A0, port 4 of switch 5 is coupled to satellite TX module, and port 5 of switch 5 is coupled to satellite RX module.

[0221] Each cellular module (such as cellular RX module 1, cellular RX module 2, cellular RX module 3, and cellular TRX module) can provide radio frequency processing for cellular signals. Each cellular module can also be coupled to a cellular baseband module.

[0222] Each satellite module (such as the satellite TX module and the satellite RX module) can provide radio frequency processing for the satellite signal. Each satellite module can also be coupled to the satellite baseband module.

[0223] Based on this Figure 10 The circuit scheme shown allows the electronic device to control the conduction state of switches 1 and 2 via the cellular baseband module. The electronic device can also control the conduction state of switch 5 via both the satellite baseband module and the cellular baseband module.

[0224] For example, Figure 11 Provided such as Figure 10 The control connection logic corresponding to the circuit scheme shown.

[0225] like Figure 11 As shown, the cellular baseband module can be configured with control port 1 and control port 2. Control port 1 can be coupled to the control terminal of switch 1, and control port 2 can be coupled to the control terminal of switch 2. Thus, through control port 1, the cellular baseband module can control the on / off state of switch 1. Similarly, through control port 2, the cellular baseband module can control the on / off state of switch 2.

[0226] In this example, the cellular baseband module can also be configured with a control port 4. This control port 4 is coupled to the control terminal of switch 5.

[0227] The satellite baseband module may be configured with a control port 3, which is coupled to the control terminal of switch 5.

[0228] Based on the above description of switch 5, in this example, the cellular baseband module and the satellite baseband module can work together to control the on / off state of switch 5.

[0229] Based on this Figure 10 The circuit connection logic shown enables the electronic device to reuse at least one cellular antenna for satellite communication while simultaneously switching cellular communication.

[0230] refer to Figure 12 It provides such as Figure 10 The circuit connection logic shown illustrates the coupling between each antenna and the RF module in the default state.

[0231] like Figure 12 As shown, in the default state, antennas A0 to A3 can all be coupled to the cellular radio frequency module for cellular communication.

[0232] For example, the cellular baseband module can control the conduction state of switch 1, switch 2 and switch 5 to implement the conduction logic of the default state mentioned above.

[0233] In some embodiments, under this default state, the cellular baseband module can control switch 1 to connect port 1 and port 4, control switch 1 to connect port 2 and port 5, control switch 5 to connect port 1 and port 3, control switch 2 to connect port 2 and port 5, and control switch 2 to connect port 3 and port 6.

[0234] In this way, antenna A0 can be coupled to the cellular TRX module via switches 5 and 2. Therefore, antenna A0 can transmit and receive signals corresponding to the cellular TRX module.

[0235] Antenna A1 can be coupled to cellular RX module 1 via switch 2. Therefore, antenna A1 can receive signals corresponding to cellular RX module 1.

[0236] Antenna A2 can be coupled to cellular RX module 2 via switch 1. Therefore, antenna A2 can receive signals corresponding to cellular RX module 2.

[0237] Antenna A3 can be coupled to cellular RX module 3 via switch 1. Therefore, antenna A3 can receive signals corresponding to cellular RX module 3.

[0238] Figure 13 A TAS state is provided, such as Figure 11 The circuit shown is a schematic diagram of its conduction logic.

[0239] In such Figure 13 In the example, antenna A0 can still be used for cellular communication. For instance, antenna A0 can be coupled to cellular RX module 2 to achieve corresponding signal reception.

[0240] In this example, the cellular baseband module can control the conduction state of switch 5 to be such that ports 1 and 2 are connected. The conduction state of switch 1 is such that ports 3 and 4 are connected.

[0241] In this way, antenna A0 can be coupled to cellular RX module 2 via switch 5 and switch 1.

[0242] Figure 14 It provides a TAS state, such as Figure 11 The circuit shown is a schematic diagram of its conduction logic.

[0243] In such Figure 14 In the example, antenna A0 continues to be used for cellular communication. For instance, antenna A0 can be coupled to cellular RX module 3 to achieve corresponding signal reception.

[0244] In this example, the cellular baseband module can control the conduction state of switch 5 to be such that port 1 and port 2 are connected. The conduction state of switch 1 can be switched to be such that port 3 and port 5 are connected.

[0245] In this way, antenna A0 can be coupled to cellular RX module 3 through switch 5 and switch 1.

[0246] It should be noted that, in cases such as Figure 13 as well as Figure 14 The example primarily illustrates the switching implementation between antenna A0 and each cellular module. For other antennas, the cellular baseband module can also control switches 1, 2, and 5 to operate in their corresponding on states, facilitating flexible communication between other antennas and the cellular module.

[0247] Based on this Figure 13 as well as Figure 14 As can be seen from the scheme description, during the TAS handover of cellular communication, the electronic device can control the conduction state of switch 1 and switch 5, or control the conduction state of switch 2 and switch 5 through the cellular baseband module, so as to realize flexible conduction between antenna A0 and each cellular module.

[0248] Compared to other solutions, such as... Figure 6 The example scheme shown enables lower insertion loss on the link where antenna A0 is located in the TAS state.

[0249] Specifically, such as Figure 6 In the scheme shown, when antenna A0 is coupled to cellular RX module 2, the corresponding link can be: antenna A0-switch 4-switch 2-switch 1-cellular RX module 2.

[0250] In such Figure 11 In the scheme shown, when antenna A0 is coupled to cellular RX module 2, the corresponding link can be: antenna A0 - switch 5 - switch 1 - cellular RX module 2.

[0251] Therefore, in such Figure 11 In the implementation of the scheme shown, the link only includes two switching components, thus saving the link loss caused by the corresponding devices.

[0252] Understandably, in current implementations, TAS switching, as a relatively mature technology, is commonly used when multiplexing cellular antennas for signal transmission and reception in other systems (such as satellite communication systems). This typically involves adding an additional switching component between the antenna and the switch, building upon the existing TAS switching link. This allows for the coupling of the antenna with the RF module of the satellite communication system when satellite communication is required.

[0253] This will inevitably lead to increased insertion loss during TAS switching due to the additional switching components. For example, in situations like... Figure 6 In the proposed solution, compared to... Figure 3 In the cellular TAS implementation shown, the insertion loss of switch 4 is added.

[0254] In contrast, in this application, as Figure 11 The provided circuit design does not simply connect the antenna to the existing TAS switching logic via a switching component. Instead, it adds a new switching component (such as switch 5) to the TAS switching logic. Thus, switch 5 is no longer a new component added for compatibility with other systems' antenna sharing schemes, but rather part of the TAS switching scheme itself. This avoids the problem of linearly increasing insertion losses on the link caused by the addition of the switching component. This also allows for the acquisition of... Figure 11 As shown, antenna A0 can be coupled to cellular RX module 2 / 3 using only switches 5 and 1. Compared to the original TAS switching logic, the link still only includes two switching components, so the insertion loss of the devices has not increased.

[0255] In this example, it is also based on, as Figure 11 The circuit logic shown provides the signal conduction logic when using antenna A0 for satellite communication.

[0256] refer to Figure 15 When antenna A0 is used for satellite TX communication, the satellite baseband module can control the conduction of port 1 and port 4 of switch 5. In this way, antenna A0 can be coupled to the satellite TX module through switch 5.

[0257] Similarly, when antenna A0 is used for satellite RX communication, the satellite baseband module can control port 1 of switch 5 to be connected to port 5. In this way, antenna A0 can be coupled to the satellite RX module through switch 5.

[0258] In some embodiments of this application, to avoid conflicts between control commands sent by the cellular baseband module and those sent by the satellite baseband module in switch 5, a priority strategy can be configured in switch 5: the satellite baseband module has a higher priority than the cellular baseband module. Thus, upon receiving a control command from the satellite baseband module, switch 5 will perform on / off control according to the control command sent by the satellite baseband module, regardless of whether it has received a control command from the cellular baseband module. This allows antenna A0 to prioritize satellite communication signal transmission and reception.

[0259] In some embodiments, if antenna A0 is conducting cellular communication before switching to satellite communication, the cellular baseband module can control switches 1 and 2 to switch the ongoing cellular communication on antenna A0 to other antennas to continue, so as to ensure that cellular communication is not interrupted.

[0260] For example, at the first moment, antenna A0 is coupled to the cellular TRX module and is performing master communication. At the second moment, antenna A0 is switched to perform satellite communication signal transmission and reception. Thus, at this second moment, the cellular baseband module can control switch 1 and / or switch 2 to couple the cellular TRX module to antenna A1, antenna A2, or antenna A3 to continue the cellular communication that was performed on antenna A0 at the first moment.

[0261] It is understandable that the above... Figure 11 The illustrated solution uses antenna multiplexing between a satellite communication system and a cellular communication system as an example. In other embodiments, based on a similar mechanism, this... Figure 11 The circuit logic shown can also be applied to antenna multiplexing in any two or more communication systems, such as satellite communication systems, cellular communication systems, GPS communication systems, WIFI communication systems, and Bluetooth communication systems. For example, in the antenna switching logic of a communication system, by adjusting its switching logic, at least one of the switching components can couple the first antenna to another communication system. This avoids situations such as... Figure 6 The problem shown is the linear superposition of link insertion losses.

[0262] It should be noted that in the above embodiments, the cellular communication system uses two switching components (such as switch 1 and switch 2) to achieve cellular TAS handover as an example. In other embodiments, the cellular communication system for achieving cellular TAS handover can also be implemented using other methods. The type and number of switching components can be different. Similar to the switching components, the type and number of radio frequency modules in the cellular communication system can also be flexibly set according to the specific implementation. This application does not impose any limitations on this.

[0263] Furthermore, in the above examples, the satellite communication can be BeiDou satellite communication, TianTong satellite communication, or other satellite communication systems. It is understood that in other embodiments, based on a similar design, multiple switching components (such as multiple switches 5) coupled to different satellite radio frequency modules can be configured in the circuit to achieve compatibility with multiple satellite systems.

[0264] For example, refer to Figure 16 This is a schematic diagram of the logic composition of another type of circuit.

[0265] In this example, the cellular antenna may specifically include: a medium-high frequency (MHB) PM antenna, an MHB DM antenna, an MHB transmit / main receive (TX / PRX) antenna, and an MHB diversity receive (DRX) antenna.

[0266] The corresponding radio frequency modules may include: Cellular TRX1, MIMO RX1, Cellular TRX2, and Cellular RX2.

[0267] For example, both cellular TRX1 and cellular TRX2 can be implemented using an MHB LPAMiD module (such as Phase7LE) with transceiver signal processing capabilities. MIMO RX1 can be implemented using a MIMO FEM. Cellular RX2 can be implemented using an LDiFEM.

[0268] This circuit logic may also include at least one satellite communication component. For example, satellite TX1 and satellite RX1 may correspond to the TX and RX radio frequency modules of one satellite communication system. Satellite TX2 and satellite RX2 may correspond to the TX and RX radio frequency modules of another satellite communication system.

[0269] Switches 6, 7, 8 and 9 can be configured between the RF module and the antenna.

[0270] Among them, switches 6, 7, and 8 can have the switching capability of switch 5 in the above embodiments. For example, switches 6, 7, and 8 can be implemented using SP4T.

[0271] Switch 9 can be configured with at least six signal transmission ports. For example, the ports on switch 9 may include: port 1, port 2, port 3, port 4, port 5, and port 6. Any one of ports 1, 2, 3, and 4 can be configured to be connected to port 5 and / or port 6. In some implementations, switch 9 can be implemented using a DP4T.

[0272] In some embodiments, the cellular baseband module can control switches 6, 7, 8 and 9 to achieve TAS switching in cellular communication.

[0273] In other embodiments, the satellite baseband module can control switches 7 and 8 to enable satellite communication using multiplexed cellular antennas. This satellite baseband module may include a BeiDou satellite baseband module and / or a TianTong satellite baseband module.

[0274] like Figure 16As shown, in this implementation, port 1 of switch 6 can be coupled to cellular TRX1, port 2 of switch 6 can be coupled to MIMO RX1, port 3 of switch 6 can be coupled to cellular TRX2, and port 4 of switch 6 can be coupled to port 3 of switch 8.

[0275] Port 1 of switch 7 can be coupled to the MHB TX / PRX antenna, port 2 of switch 7 can be coupled to the cellular TRX2, port 3 of switch 7 can be coupled to the satellite TX1, port 4 of switch 7 can be coupled to the satellite RX1, and port 5 of switch 7 can be coupled to port 3 of switch 9.

[0276] Port 1 of switch 8 can be coupled to the MHB DRX antenna, port 2 of switch 8 can be coupled to port 4 of switch 9, port 3 of switch 8 can be coupled to port 4 of switch 6, port 4 of switch 8 can be coupled to satellite TX2, and port 5 of switch 8 can be coupled to satellite RX2.

[0277] Port 1 of switch 9 can be coupled to MIMO RX1, port 2 of switch 9 can be coupled to cellular TRX1, port 3 of switch 9 can be coupled to port 5 of switch 7, port 4 of switch 9 can be coupled to port 2 of switch 8, port 5 of switch 9 can be coupled to cellular TRX2, and port 6 of switch 9 can be coupled to cellular RX2.

[0278] Based on such Figure 16 The circuit logic shown allows the cellular baseband module to control the conduction of ports 1 and 2 of switch 8, and ports 4 and 6 of switch 9, thereby coupling the MHB DRX antenna with the cellular RX2 and enabling DRX communication in the default state.

[0279] The cellular baseband module can control the conduction of ports 1 and 2 of switch 7, so that the MHB TX / PRX antenna is coupled to the cellular TRX2, realizing TX / PRX communication in the default state.

[0280] In this implementation, the MHB PM antenna can be directly connected to the cellular TRX1 to enable normally-on MIMO PM communication. The MHBDM antenna can be directly connected to the MIMO RX1 to enable normally-on MHB DM communication.

[0281] In this example, the satellite baseband module can control switches 7 and 8, enabling satellite communication via cellular antenna multiplexing. Taking satellites TX1 and RX1 as corresponding to the BeiDou satellite communication system, with the corresponding satellite baseband module being satellite baseband module 1; and satellites TX2 and RX2 as corresponding to the Tiantong satellite communication system, with the corresponding satellite baseband module being satellite baseband module 2, as an example.

[0282] In some embodiments, the satellite baseband module 1 can control the switch 7 to connect port 1 and port 3 so that the MHBTX / PRX antenna is coupled to the satellite TX1, thereby realizing the signal transmission of BeiDou satellite communication based on the MHB TX / PRX antenna.

[0283] The satellite baseband module 1 can control the connection of port 1 and port 4 of switch 7 to enable the MHB TX / PRX antenna to be coupled to satellite RX1, thereby realizing the signal reception of Beidou satellite communication based on the MHB TX / PRX antenna.

[0284] In other embodiments, the satellite baseband module 2 can control the switching 8 to connect port 1 and port 4, so that the MHB DRX antenna is coupled to the satellite TX2, thereby realizing the signal transmission of Tiantong satellite communication based on the MHB DRX antenna.

[0285] The satellite baseband module 2 can control the connection of port 1 and port 5 of switch 8 to couple the MHB DRX antenna with satellite RX2, thereby enabling signal reception of Tiantong satellite communication based on the MHB DRX antenna.

[0286] Combination such as Figure 11 As explained in the description, in some embodiments, if the cellular antenna is transmitting or receiving cellular signals before multiplexing the cellular antenna for satellite communication, the electronic device (such as a cellular baseband module) can switch the ongoing cellular communication signal to another cellular antenna to continue transmitting and receiving.

[0287] In this example, as Figure 16 In the circuit configuration shown, since switches 7 and 8 are respectively configured as part of the TAS switching logic, the switching is compatible with satellite communication and does not cause additional losses in cellular TAS switching.
