[0032] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0033] A radio frequency circuit, an information transceiver system, and a method for controlling a switch state according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present application discloses a radio frequency circuit, including multiple antenna interfaces, multiple first switches corresponding to the antenna interfaces one by one, and two transceiver modules, each of which includes multiple second switches, multiple third switches, a fourth switch, a signal processor, and multiple information transceiver interfaces. In each transceiver module, the multiple second switches, the multiple third switches, and the multiple information transceiver interfaces all correspond to the antenna interfaces one by one.

[0035] The movable end of each first switch is connected to the corresponding antenna interface, the first fixed end of the first switch is connected to the movable end of the second switch in the receiving module, and the second fixed end of the first switch is connected to the movable end of the second switch in the sending module;

[0036] In each transceiver module:

[0037] The movable end of each third switch is connected to the corresponding information transceiver interface, the first fixed end of each third switch is connected to the first fixed end of the corresponding second switch, and the second fixed end of each third switch is connected to a device-side signal end of the corresponding signal processor;

[0038] The movable end of the fourth switch is connected to the antenna-side signal end of the signal processor, and each fixed end of the fourth switch is respectively connected to the second fixed end of the corresponding second switch;

[0039] The two transceiver modules are a receiving module and a sending module respectively. The information transceiver interface in the receiving module is an information receiving interface, and the information transceiver interface in the sending module is an information sending interface.

[0040] It can be understood that when the radio frequency circuit includes n antenna interfaces, n is an integer greater than 1, the first switch in the radio frequency circuit corresponds to the antenna interface one by one; in each transceiver module, the number of the second switch, the third switch and the information transceiver interface is the same as the number of the antenna interface, that is, n, wherein the first switch, the second switch and the third switch are all single-pole double-throw switches, and the endpoints of each single-pole double-throw switch include a moving end, a first fixed end and a second fixed end; the number of the fourth switch and the signal processor in each transceiver module is one, the fourth switch is a single-pole multi-throw switch, the number of the fixed ends of the fourth switch is the same as the number of the antenna interface, that is, n, and multiple fixed ends are The second fixed ends of multiple second switches in the transceiver module are respectively connected, which essentially correspond to multiple antenna interfaces one by one; the signal processor is specifically a splitter or a combiner, and each signal processor has an antenna side signal end, which is used to connect to the moving end of the fourth switch. The fourth switch determines that the fixed end connected to the moving end is connected to the antenna interface, and which antenna interface is specifically connected needs to be determined according to the actual switch state; each signal processor has multiple device side signal ends, and the multiple device side signal ends are respectively connected to the second fixed ends of multiple third switches, which essentially correspond to multiple information transceiver interfaces one by one.

[0041] It can be understood that the connection structures of the two transceiver modules, the receiving module and the sending module are exactly the same, but there are differences in the specific types of signal processors and information transceiver interfaces, wherein the information transceiver interface in the receiving module is an information receiving interface, and the information transceiver interface in the sending module is an information sending interface; the signal processor of the receiving module is a splitter, and the signal processor of the sending module is a combiner; wherein the splitter is used to divide the single-channel information received by the antenna side signal end into multiple channels and output them from multiple device side signal ends, and the combiner is used to integrate the multiple channels of information received by multiple device side signal ends into a single-channel information and output it from the antenna side signal end.

[0042] Therefore, if Figure 1 The schematic diagram of the partial structure of a radio frequency circuit is shown. In the radio frequency circuit, for an antenna interface P1, the components involved in the related circuit include: the corresponding first switch S1, the second switch SR12, the third switch SR13, the fourth switch SR4, the splitter, the information receiving interface RX1 in the receiving module, the second switch ST12, the third switch ST13, the fourth switch ST4, the combiner, and the information sending interface TX1 in the sending module. The fourth switch SR4 in the receiving module, the splitter, the fourth switch ST4 in the sending module, and the combiner are common components, which are shared by all antenna interfaces.

[0043] It can be understood that when adding antenna interfaces, the reused common elements and antenna interfaces remain unchanged, and the number of to-be-connected ends corresponding to the antenna interfaces on the common elements is adjusted with the number of antenna interfaces. At this time, corresponding to the added antenna interfaces, the first switch and the second switch, the third switch and the information transceiver interface in the two transceiver modules will also be added accordingly.

[0044] like Figure 2 A specific radio frequency circuit is shown, and the radio frequency circuit includes two antenna interfaces, which are respectively marked as P1 and P2. At this time, the component identification involved in P1 is the same as Figure 1 In addition, the RF circuit also includes components corresponding to P2: a first switch S2 corresponding to P2, a second switch SR22, a third switch SR23, and an information receiving interface RX2 in the receiving module, and a second switch ST22, a third switch ST23, and an information sending interface TX2 in the sending module.

[0045] Therefore, it can be understood that the above-mentioned components can be marked according to the following rules: Assume that the antenna interface is marked as Pi, i is an integer between 1 and n, the first switch corresponding to Pi is Si, the switches in the receiving module are all marked as SR, the switches in the sending module are all marked as ST, the second switch corresponding to Pi in the receiving module is marked as SRi2, the third switch corresponding to Pi is marked as SRi3, the information receiving interface corresponding to Pi is marked as RXi, the second switch corresponding to Pi in the sending module is marked as STi2, the third switch corresponding to Pi is marked as STi3, and the information sending interface corresponding to Pi is marked as TXi. There is only one splitter in the entire RF circuit, marked as a splitter, and only one combiner, marked as a combiner. There is only one fourth switch in the receiving module, marked as SR4, and there is only one fourth switch in the sending module, marked as ST4.

[0046] It can be understood that the antenna interface of the RF circuit is used to connect to the antenna to realize the transmission and reception of information between the antenna and the RF circuit; the information transmission and reception interface is used to connect to the device, for example, the information receiving interface is used to connect to the ADC (Analog-to-Digital Converter) device and send relevant information to the ADC device, and the information sending interface is used to connect to the DAC (Digital-to-Analog Converter) device and receive information sent by the DAC device.

[0047] It can be understood that for each antenna interface, by setting the switching states of the corresponding first switch, second switch, third switch, and fourth switch, the working state of the antenna interface can be adjusted to different modes, where the working modes of the antenna interface include single-receive mode, single-transmit mode, diversity reception mode, and diversity transmission mode. It should be noted that the same antenna interface can be in at most one working mode at the same time, and different working modes will not occur simultaneously on the same antenna interface.

[0048] Among them, the single receiving mode means that the antenna interface Pi is connected to the corresponding information receiving interface RXi one-to-one, and the path does not pass through the signal processor. When the antenna receives external information, it will pass the external information to the device connected to the information receiving interface through the path between the antenna interface and the information receiving interface;

[0049] Similarly, the single-transmission mode means that the antenna interface Pi is connected to the corresponding information transmission interface TXi in a one-to-one manner, and the path does not pass through the signal processor. The device connected to the information transmission interface outputs information, and the information is transmitted to the antenna through the path between the information transmission interface and the antenna interface, and then transmitted to the outside by the antenna.

[0050] Furthermore, the diversity reception mode means that the antenna interface is connected to the antenna side signal end of the splitter one-to-one, the device side signal end of the splitter is connected to the corresponding one or more information receiving interfaces, the antenna sends the external information to the splitter when receiving the external information, and the splitter distributes the external information to the device connected to the information receiving interface through the connected information receiving interface after splitting the external information;

[0051] Similarly, the diversity transmission mode refers to a one-to-one connection between the antenna interface and the antenna side signal end of the combiner, the device side signal end of the combiner is connected to the corresponding one or more information sending interfaces, the devices connected to the information sending interfaces send information to the combiner respectively, the combiner receives the information and integrates it and sends it to the corresponding antenna interface, so that the antenna transmits the information to the outside.

[0052] It can be understood that different paths need to be turned on in the single-receive mode, the single-transmit mode, the diversity receive mode, and the diversity transmit mode, and the path conduction is achieved by corresponding switches.

[0053] Specifically, when the target antenna interface is in the single receiving mode, the moving end of the first switch corresponding to the target antenna interface is connected to the first fixed end of the first switch, and in the receiving module, the moving end of the second switch corresponding to the target antenna interface is connected to the first fixed end of the second switch, and the moving end of the third switch corresponding to the target antenna interface is connected to the first fixed end of the third switch;

[0054] The target antenna interface is any antenna interface.

[0055] Similarly, when the target antenna interface is in the single-transmission mode, the movable end of the first switch corresponding to the target antenna interface is connected to the second fixed end of the first switch, and in the transmitting module, the movable end of the second switch corresponding to the target antenna interface is connected to the first fixed end of the second switch, and the movable end of the third switch corresponding to the target antenna interface is connected to the first fixed end of the third switch;

[0056] The target antenna interface is any antenna interface.

[0057] Further, when the target antenna interface is in the diversity receiving mode, the moving end of the first switch corresponding to the target antenna interface is connected to the first fixed end of the first switch, in the receiving module, the moving end of the second switch corresponding to the target antenna interface is connected to the second fixed end of the second switch, the fixed end corresponding to the target antenna interface in the fourth switch is connected to the moving end of the fourth switch, and the moving end of the third switch corresponding to each target transceiver interface is connected to the second fixed end of the corresponding third switch;

[0058] The target antenna interface is any antenna interface, and the target transceiver interface is an information transceiver interface corresponding to the current mode of the target antenna interface.

[0059] Similarly, when the target antenna interface is in the diversity transmission mode, the movable end of the first switch corresponding to the target antenna interface is connected to the second fixed end of the first switch, in the transmitting module, the movable end of the second switch corresponding to the target antenna interface is connected to the second fixed end of the second switch, the fixed end corresponding to the target antenna interface in the fourth switch is connected to the movable end of the fourth switch, and the movable end of the third switch corresponding to each target transceiver interface is connected to the second fixed end of the corresponding third switch;

[0060] The target antenna interface is any antenna interface, and the target transceiver interface is an information transceiver interface corresponding to the current mode of the target antenna interface.

[0061] It is understandable that Figure 2 Taking the RF circuit of the dual antenna interface as an example, assuming that the target antenna interface is P1, when it is in the single receiving mode, the moving end of the first switch S1 corresponding to the target antenna interface P1 is connected to the first fixed end of the first switch S1, and in the receiving module, the moving end of the second switch SR12 corresponding to the target antenna interface P1 is connected to the first fixed end of the second switch SR12, and the moving end of the third switch SR13 corresponding to the target antenna interface P1 is connected to the first fixed end of the third switch SR13. At this time, the target antenna interface P1 is connected to the corresponding information receiving interface RX1 through switches S1, SR12, and SR13, as shown in FIG. Figure 3 shown.

[0062] Similarly, Figure 2Taking the RF circuit of the dual antenna interface as an example, assuming that the target antenna interface is P1, when it is in the single-transmission mode, the moving end of the first switch S1 corresponding to the target antenna interface P1 is connected to the second fixed end of the first switch S1, and in the sending module, the moving end of the second switch ST12 corresponding to the target antenna interface P1 is connected to the first fixed end of the second switch ST12, and the moving end of the third switch ST13 corresponding to the target antenna interface P1 is connected to the first fixed end of the third switch ST13. At this time, the target antenna interface is connected to the corresponding information sending interface TX1 through switches S1, ST12, and ST13, as shown in FIG. Figure 4 shown.

[0063] Understandably, Figure 2 Taking the RF circuit of the dual antenna interface as an example, assuming that the target antenna interface is P1, which is in diversity reception mode, assuming that the corresponding target transceiver interface is the information receiving interface RX1 and RX2, at this time: the moving end of the first switch S1 corresponding to the target antenna interface P1 is connected to the first fixed end of the first switch S1, in the receiving module, the moving end of the second switch SR12 corresponding to the target antenna interface P1 is connected to the second fixed end of the second switch SR12, the fixed end of the target antenna interface P1 in the fourth switch SR4 is connected to the moving end of the fourth switch SR4, the moving end of the third switch SR13 corresponding to the target transceiver interface RX1 is connected to the second fixed end of the third switch SR13, and the moving end of the third switch SR23 corresponding to the target transceiver interface RX2 is connected to the second fixed end of the third switch SR23; at this time, the target antenna interface is connected to the two target transceiver interfaces RX1 and RX2 through switches S1, SR12, SR4, splitters splitter, SR13, SR23, such as Figure 5 shown.

[0064] Understandably, Figure 2 Taking the RF circuit of the dual antenna interface as an example, assuming that the target antenna interface is P1, which is in diversity transmission mode, assuming that the corresponding target transceiver interface is the information sending interface TX1 and TX2, at this time: the moving end of the first switch S1 corresponding to the target antenna interface P1 is connected to the second fixed end of the first switch S1, in the sending module, the moving end of the second switch ST12 corresponding to the target antenna interface P1 is connected to the second fixed end of the second switch ST12, the fixed end of the target antenna interface P1 in the fourth switch ST4 is connected to the moving end of the fourth switch ST4, the moving end of the third switch ST13 corresponding to the target transceiver interface TX1 is connected to the second fixed end of the third switch ST13, and the moving end of the third switch ST23 corresponding to the target transceiver interface TX2 is connected to the second fixed end of the third switch ST23; at this time, the target antenna interface is connected to both the two target transceiver interfaces TX1 and TX2 through switches S1, ST12, ST4, combiners combiner, ST13, ST23, such as Figure 6 shown.

[0065] It can be understood that in the control of all working modes of the antenna interface, the first switch connected to each antenna interface is used to switch the connection status of the two transceiver modules of the antenna interface. When the moving end of the first switch is connected to the first fixed end, the antenna interface is connected to the receiving module, and the antenna interface is in the receiving mode. When the moving end of the first switch is connected to the second fixed end, the antenna interface is connected to the sending module, and the antenna interface is in the sending mode.

[0066] Furthermore, the second switch in each transceiver module is used to switch the corresponding antenna interface in the current transceiver module to single-channel transceiver or diversity transceiver. When the movable end of the second switch is connected to the first fixed end, the corresponding antenna interface is in single-channel transceiver. When the movable end of the second switch is connected to the second fixed end, the corresponding antenna interface is in diversity transceiver. Of course, single-channel transceiver or diversity transceiver also requires the cooperation of the third switch or the fourth switch.

[0067] Furthermore, the third switch in each transceiver module is used to switch the information transceiver interface connected to the third switch to single-channel transceiver or diversity transceiver. When the active end of the third switch is connected to the first fixed end, the corresponding information transceiver interface is in single-channel transceiver. When the active end of the third switch is connected to the second fixed end, the corresponding information transceiver interface is connected to the information processor and is in diversity transceiver.

[0068] Furthermore, the fourth switch in each transceiver module is used to switch the antenna interface connected to the antenna side signal end of the current information processor, that is, the moving end of the fourth switch is connected to any fixed end, and the antenna side signal end of the information processor is connected to the corresponding antenna interface through the fourth switch, providing a basic premise for diversity transceiver of the antenna interface.

[0069] It can be understood that the antenna interface directly corresponds to the first switch and the second switches in the two transceiver modules. The first switch controls the antenna interface to switch between the receiving state and the transmitting state, and each second switch controls the corresponding antenna interface to switch between the single-channel transceiver state and the diversity transceiver state; the third switch corresponds to each information transceiver interface one by one, and the third switch controls the corresponding information transceiver interface to switch between the single-channel transceiver state and the diversity transceiver state. It can be understood that the position of the information transceiver interface determines whether it is in the receiving state or the transmitting state, that is, the information transceiver interface in the receiving module is the information receiving interface in the receiving state, and the information transceiver interface in the transmitting module is the information transmitting interface in the transmitting state; whether the information transceiver interface is single-channel transceiver or diversity transceiver is controlled by the third switch; whether the antenna interface is receiving state or transmitting state is controlled by the first switch, and whether the antenna interface is single-channel transceiver or diversity transceiver is controlled by the second switch.

[0070] Specifically, the one-to-one correspondence between the antenna interface and the information transceiver interface is valid when the antenna interface is in a single-receive mode or a single-transmit mode, that is, when the target antenna interface is in a single-receive mode or a single-transmit mode, the corresponding target transceiver interface is a unique and definite information transceiver interface; when the antenna interface is in a diversity transceiver mode, the transceiver module to be connected to the antenna interface is first determined, that is, the transceiver module to be connected is determined as a transmitting module according to the diversity transmission mode, and the transceiver module to be connected is determined as a receiving module according to the diversity reception mode. All information transceiver interfaces in the determined transceiver module can participate in the diversity transceiver of the antenna interface, that is, all information transceiver interfaces in the determined transceiver module can be used as the target transceiver interface corresponding to the current mode of the target antenna interface, or, the target transceiver interface is any information transceiver interface in the transceiver module corresponding to the current mode of the target antenna interface. It is understandable that the number of target transceiver interfaces is not required to be multiple. A single target transceiver interface and a target antenna interface can also establish a connection through a signal processor, thereby realizing information transmission and reception between the target transceiver interface and the target antenna interface. In fact, the emergence of the signal processor not only realizes the needs of one-to-many and many-to-one signal links, but also decouples the original one-to-one correspondence between the antenna interface and the information transceiver interface in single-channel transmission and reception through the signal processor. Any antenna interface can realize information transmission with any information transceiver interface through the signal processor, thereby improving the flexibility of the correspondence between the antenna interface and the information transceiver interface.

[0071] When a certain antenna interface corresponds to the state of the corresponding information transceiver interface, for example, when the antenna interface is in the single-receive state and the corresponding information receiving interface is in the single-channel transceiver state, the antenna interface is connected to the information transceiver interface to become an enabling communication link.

[0072] Furthermore, the switch states between multiple antenna interfaces and multiple information transceiver interfaces can be flexibly adjusted, so as to realize various working requirements for different antenna interfaces and different information transceiver interfaces. For a radio frequency circuit with multiple antenna interfaces, the radio frequency circuit allows multiple antenna interfaces to be in working state at the same time, as long as the working state of each antenna interface does not affect the working state of other antenna interfaces.

[0073] When each antenna interface is single-channel, it will not affect the working status of other antenna interfaces. Figure 2 As shown, both antenna interfaces are in single-transmission mode. Figure 3 As shown, the antenna interface P1 is in a single-receive mode, and the antenna interface P2 is in a single-transmit mode.

[0074] In fact, even if a certain antenna interface is in diversity transmission and reception, as long as it does not affect the information transmission and reception interface corresponding to the current working mode of other antenna interfaces, the RF circuit can work normally, for example Figure 5As shown, the antenna interface P1 is in the diversity receiving mode corresponding to the information receiving interface RX1 and RX2. At this time, the antenna interface P2 cannot perform the working state related to the information receiving interface RX2, but other working modes can still be used, such as the antenna interface P2 is in the single-transmission mode, the diversity transmission mode, etc. Figure 5 This is an example of the antenna interface P2 being in diversity transmission mode.

[0075] It can be understood that if the antenna interfaces include P1, P2 and P3, when the antenna interface P1 is in the single-receiving mode, the information receiving interface RX1 is occupied, and the optional working modes of the antenna interface P2 include the single-receiving mode, the single-transmitting mode, the diversity transmitting mode, and the diversity receiving mode. It should be noted that the information receiving interface corresponding to the diversity receiving mode does not include the information receiving interface RX1 occupied by the antenna interface P1.

[0076] It is understandable that in the radio frequency circuit, as long as the antenna interface and the information transceiver interface of each working mode and the occupation of the fourth switch are different, multiple working modes can be enabled in the radio frequency circuit at the same time, for example Figure 3 The antenna interface P1 is in single-receive mode, and the antenna interface P2 is in single-transmit mode. Figure 4 The antenna interface P1 is in single-transmission mode, and the antenna interface P2 is in diversity transmission mode corresponding to the information transmission interface TX2, for example Figure 5 The antenna interface P1 is in the diversity receiving mode corresponding to the information receiving interface RX1 and RX2, and the antenna interface P2 is in the diversity transmitting mode corresponding to the information sending interface TX1 and TX2. Figure 6 The antenna interface P1 is in diversity transmission mode, and the antenna interface P2 is in single reception mode.

[0077] It is understandable that each switch corresponding to the current working mode in the RF circuit must be in the corresponding switch state, but there is no mandatory requirement for the switch state of other switches that are not related to the current working state and do not participate in the current working mode, and they can be adjusted or not acted upon according to actual conditions.

[0078] It is understandable that as the number of antenna interfaces increases, the number of working modes that the RF circuit can achieve will increase exponentially. Compared with the prior art, when realizing the same signal mode user requirements, the RF circuit of this embodiment will use fewer antenna interfaces and antennas. When using the same antenna, this embodiment can achieve significantly more working modes. Therefore, this embodiment greatly broadens the application scenarios of the RF circuit with a limited number of antennas and can meet various user requirements.

[0079] The embodiment of the present application realizes different scenarios of signal reception and transmission by setting an antenna interface, a first switch, a second switch, a third switch, a fourth switch, a signal processor, and an information transceiver interface in the radio frequency circuit, and utilizing the state switching of each switch. Each antenna interface can support different application scenarios, so that the radio frequency circuit of the present application realizes different user needs with a smaller number of antennas, and overcomes the problems of volume and communication quality caused by too many antennas.

[0080] The present application also discloses an information receiving and sending system. Figure 7 As shown, including:

[0081] The radio frequency circuit 701 as in any one of the above embodiments;

[0082] A controller 702 for controlling the switch states of all switches in the radio frequency circuit 701; the switches include a first switch, a second switch, a third switch and a fourth switch;

[0083] A transceiver antenna 703 connected to each antenna interface of the radio frequency circuit 701 .

[0084] The specific implementation details of the radio frequency circuit 701 may refer to the specific contents in the above embodiments, which will not be described again here.

[0085] Among them, the transceiver antennas 703 correspond one-to-one with the antenna interfaces of the radio frequency circuit 701, and the specific number corresponds to the number of the antenna interfaces, which is usually not less than 2.

[0086] Among them, the controller 702 is used to determine the target antenna interface and the corresponding control mode according to the mode instruction sent by the user through the upper computer, and the control mode includes at least one of a single-receive mode, a single-transmit mode, a diversity receive mode, and a diversity transmit mode. When determining the control mode corresponding to the target antenna interface, the corresponding target transceiver interface will also be determined. Finally, the switch in the RF circuit 701 is controlled to switch to the corresponding switch state to achieve connectivity between the target antenna interface and the target transceiver module.

[0087] The embodiment of the present application realizes different scenarios of signal reception and transmission by setting an antenna interface, a first switch, a second switch, a third switch, a fourth switch, a signal processor, and an information transceiver interface in the radio frequency circuit, and utilizing the state switching of each switch. Each antenna interface can support different application scenarios, so that the radio frequency circuit of the present application realizes different user needs with a smaller number of antennas, and overcomes the problems of volume and communication quality caused by too many antennas.

[0088] Figure 8 It is a flow chart of a method for controlling a switch state provided in an embodiment of the present application. Figure 8 The control method can be Figure 7The controller is executed. Figure 8 As shown, the control method includes:

[0089] S801: receiving mode instruction;

[0090] S802: Determine the target antenna interface and the corresponding control mode according to the mode instruction; the control mode includes at least one of a single-receive mode, a single-transmit mode, a diversity receive mode, and a diversity transmit mode;

[0091] S803: Based on the target antenna interface and the corresponding control mode, adjust the corresponding switch to a corresponding switch state.

[0092] The embodiment of the present application realizes different scenarios of signal reception and transmission by setting an antenna interface, a first switch, a second switch, a third switch, a fourth switch, a signal processor, and an information transceiver interface in the radio frequency circuit, and utilizing the state switching of each switch. Each antenna interface can support different application scenarios, so that the radio frequency circuit of the present application realizes different user needs with a smaller number of antennas, and overcomes the problems of volume and communication quality caused by too many antennas.

[0093] It is understandable that when the control mode is different, the switches to be adjusted are different and the corresponding switch states are different, so the switch states adjusted in step S803 may include:

[0094] When the target antenna interface is in the single receiving mode, the moving end of the first switch corresponding to the target antenna interface is connected to the first fixed end of the first switch, and in the receiving module, the moving end of the second switch corresponding to the target antenna interface is connected to the first fixed end of the second switch, and the moving end of the third switch corresponding to the target antenna interface is connected to the first fixed end of the third switch;

[0095] The target antenna interface is any antenna interface.

[0096] Similarly, when the target antenna interface is in the single-transmission mode, the movable end of the first switch corresponding to the target antenna interface is connected to the second fixed end of the first switch, and in the transmitting module, the movable end of the second switch corresponding to the target antenna interface is connected to the first fixed end of the second switch, and the movable end of the third switch corresponding to the target antenna interface is connected to the first fixed end of the third switch;

[0097] The target antenna interface is any antenna interface.

[0098] Further, when the target antenna interface is in the diversity receiving mode, the moving end of the first switch corresponding to the target antenna interface is connected to the first fixed end of the first switch, in the receiving module, the moving end of the second switch corresponding to the target antenna interface is connected to the second fixed end of the second switch, the fixed end corresponding to the target antenna interface in the fourth switch is connected to the moving end of the fourth switch, and the moving end of the third switch corresponding to each target transceiver interface is connected to the second fixed end of the third switch;

[0099] The target antenna interface is any antenna interface, and the target transceiver interface is an information transceiver interface corresponding to the current mode of the target antenna interface.

[0100] Similarly, when the target antenna interface is in the diversity transmission mode, the movable end of the first switch corresponding to the target antenna interface is connected to the second fixed end of the first switch, in the transmitting module, the movable end of the second switch corresponding to the target antenna interface is connected to the second fixed end of the second switch, the fixed end corresponding to the target antenna interface in the fourth switch is connected to the movable end of the fourth switch, and the movable end of the third switch corresponding to each target transceiver interface is connected to the second fixed end of the corresponding third switch;

[0101] The target antenna interface is any antenna interface, and the target transceiver interface is an information transceiver interface corresponding to the current mode of the target antenna interface.

[0102] Considering that when multiple target antenna interfaces are set at the same time, it is necessary to ensure that the target transceiver interface corresponding to each target antenna interface in the RF circuit is different, a detection action can be added after determining the control mode in step S802 and before adjusting the switch in step S803. The specific detection action is performed as follows:

[0103] Before adjusting the corresponding switch to the corresponding switch state based on the target antenna interface and the corresponding control mode, the method further includes:

[0104] Determine whether there is overlap between target transceiver interfaces corresponding to two target antenna interfaces;

[0105] If not, executing the step of adjusting the corresponding switch to a corresponding switch state based on the target antenna interface and the corresponding control mode;

[0106] If yes, select the operation according to the default.

[0107] It can be understood that the target transceiver interface overlap means that there is a target transceiver interface that is the same among the target transceiver interfaces corresponding to at least two target antenna interfaces, but it is not mandatory that all the target transceiver interfaces corresponding to the two target antenna interfaces must be exactly the same.

[0108] Among them, the preset selection can be an upload error message, which is used to indicate that there is a conflict in the mode instruction; the preset selection can also be to execute the corresponding control mode according to a preset priority or a preset execution strategy. The preset priority includes but is not limited to the priority between different control modes and the priority between different antenna interfaces. For example, two target antenna interfaces correspond to the same information receiving interface. If the priority of the single receiving mode is higher than that of the diversity reception, the information receiving interface is preferentially allocated to the target antenna interface of the single receiving mode. If the preset priority is the priority between antenna interfaces, the target antenna interface is preferentially allocated to the target antenna interface with a higher priority; the preset execution strategy includes: ignoring the target antenna interface of the overlapping target transceiver interface, adjusting the switch state of the switches corresponding to other target antenna interfaces; and not adjusting the switch state of all switches.

[0109] It is understandable that the preset selection operation can be set according to actual conditions or user needs and is not limited here.

[0110] All the above optional technical solutions can be combined in any way to form optional embodiments of the present application, and will not be described in detail here. It should be understood that the size of the sequence number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.
