Description

Technical Field

[0001] This disclosure relates to the field of antenna technology, and in particular to a vehicle-mounted antenna signal communication method, apparatus, computer equipment, and storage medium. Background Technology

[0002] In recent years, vehicular communication has received increasing attention. Vehicular communication systems use vehicles as carriers and can transmit wireless signals while moving with the vehicle. This not only allows for timely information exchange between vehicles but also enables communication with existing roadside communication infrastructure, access to the internet, and other services. Two-way relay can reduce the spectrum efficiency loss of traditional single-path half-duplex relay, save time slots used for data forwarding, increase overall network throughput, and improve network performance. Combining two-way relay with vehicular communication allows user vehicles and roadside base stations to fully utilize the spectrum through two-way communication, improving spectrum efficiency.

[0003] However, traditional two-way repeaters can only solve the communication efficiency problem between the vehicle-mounted antenna and the external base station, as shown in patent applications CN114829204A and CN114731299A. For independent communication devices used inside the vehicle, such as mobile phones and iPads used by passengers, signal anomalies frequently occur when communicating with the outside world. This can easily lead to instability in the use of mobile devices inside the vehicle, such as inaccurate navigation on a mobile phone. Consequently, the communication signal cannot remain stable, thus affecting communication quality. Summary of the Invention

[0021] This disclosure relates to a vehicle-mounted antenna signal communication method.

[0022] Please see Figure 1This is a flowchart of a vehicle-mounted antenna signal communication method according to an embodiment of the present disclosure. The vehicle-mounted antenna signal communication method includes some or all of the following steps.

[0023] S100: Obtain the full-duplex communication status parameters of the vehicle-mounted antenna repeater.

[0024] In this embodiment, the duplex communication status parameter is the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication status parameter is the real-time duplex communication status of the vehicle-mounted antenna repeater, and also corresponds to the current duplex communication mode of the vehicle-mounted antenna repeater. By collecting the duplex communication status parameter, it is easy to determine the operating state of the duplexer in the vehicle-mounted antenna repeater. The vehicle-mounted antenna repeater has at least one communication channel, and each communication channel has at least two built-in duplexers. One duplexer controls the signal transmission and reception of the external antenna, and the other duplexer controls the signal transmission and reception of the internal antenna. See details below. Figure 2 and Figure 3 The external antenna is the vehicle-mounted antenna, while the internal antenna is the antenna for the mobile devices used by the occupants inside the vehicle.

[0025] S200: Perform channel likelihood processing on the duplex communication status parameters and preset communication status parameters to obtain the duplex communication likelihood quantity.

[0026] In this embodiment, the duplex communication status parameter is the duplex communication data of the vehicle-mounted antenna repeater, that is, the real-time duplex communication status of the vehicle-mounted antenna repeater, which corresponds to the current duplex communication mode of the vehicle-mounted antenna repeater. Collecting the duplex communication status parameter facilitates determining the operating state of the duplexer within the vehicle-mounted antenna repeater. The preset communication status parameter is the standard duplex communication data of the vehicle-mounted antenna repeater, that is, the preset communication status parameter is the designated duplex communication state of the vehicle-mounted antenna repeater, which corresponds to the reference duplex communication mode of the vehicle-mounted antenna repeater. Channel likelihood processing of the duplex communication status parameter and the preset communication status parameter facilitates determining the degree of difference in the current duplex communication state of the vehicle-mounted antenna repeater.

[0027] S300: Send an attenuation failure signal to the channel attenuator according to the duplex communication likelihood to adjust the channel signal strength.

[0028] In this embodiment, the duplex communication likelihood is obtained based on the duplex communication state parameters and preset communication state parameters. The duplex communication state parameters are the duplex communication data of the vehicle-mounted antenna repeater, representing the real-time duplex communication state of the vehicle-mounted antenna repeater, and corresponding to the current duplex communication mode of the vehicle-mounted antenna repeater. Collecting these duplex communication state parameters facilitates determining the operating state of the duplexer within the vehicle-mounted antenna repeater. The preset communication state parameters are the standard duplex communication data of the vehicle-mounted antenna repeater, representing the specified duplex communication state of the vehicle-mounted antenna repeater, and corresponding to the reference duplex communication mode of the vehicle-mounted antenna repeater. Channel likelihood processing of the duplex communication state parameters and preset communication state parameters facilitates determining the degree of difference in the current duplex communication state operation of the vehicle-mounted antenna repeater. After obtaining the duplex communication likelihood, the duplex communication state of the vehicle antenna repeater is determined. Then, by sending an attenuation failure signal to the channel attenuator, the attenuation value of the attenuator in the vehicle antenna repeater is adjusted, which facilitates the adjustment of the duplex communication signal strength, making the communication signal between the internal and external antennas of the vehicle stable and effectively improving the duplex communication quality between the internal and external antennas of the vehicle.

[0029] In this embodiment, after collecting the duplex communication status parameters, the communication status changes of the vehicle-mounted antenna repeater under the current duplex communication mode are determined. Then, the duplex communication status is compared with the standard communication status to determine the degree of difference in the duplex communication status changes of the vehicle-mounted antenna repeater. Finally, based on the degree of difference, the signal attenuation mode in the duplex communication is adjusted to provide feedback adjustment to the working conditions of the channel attenuator, thereby stabilizing the communication signal between the internal and external antennas of the vehicle and effectively improving the duplex communication quality between the internal and external antennas of the vehicle.

[0030] In one embodiment, acquiring the duplex communication status parameters of the vehicle-mounted antenna includes acquiring the duplex input signal strength of the receiving channel of the vehicle-mounted antenna repeater. In this embodiment, the duplex communication status parameters are the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication status parameters are the real-time duplex communication status of the vehicle-mounted antenna repeater, and also correspond to the current duplex communication mode of the vehicle-mounted antenna repeater. By acquiring the duplex communication status parameters, it is convenient to determine the working state of the duplexer in the vehicle-mounted antenna repeater. The duplex communication status parameters include the duplex input signal strength of the receiving channel of the vehicle-mounted antenna repeater, which is the communication signal strength corresponding to the receiving channel of the duplexer in the vehicle-mounted antenna repeater. By acquiring the duplex input signal strength of the receiving channel, it is convenient to determine the signal strength of the built-in antenna when receiving the communication signal of the external antenna. The duplex input signal strength of the receiving channel is acquired by the detector tube in the vehicle-mounted antenna repeater, so as to facilitate subsequent detection by the OPA operational amplifier input to the vehicle MCU. The receiving channel is a channel where the built-in antenna receives signals from an external antenna. Further, channel likelihood processing is performed on the duplex communication state parameters and preset communication state parameters to obtain the duplex communication likelihood quantity, including: calculating the likelihood loss between the received channel duplex input signal strength and the preset received signal strength to obtain the received channel signal loss. In this embodiment, the duplex communication state parameters are the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication state parameters are the real-time duplex communication state of the vehicle-mounted antenna repeater, and also correspond to the current duplex communication mode of the vehicle-mounted antenna repeater. By collecting the duplex communication state parameters, it is easy to determine the working state of the duplexer in the vehicle-mounted antenna repeater. The preset communication state parameters are the standard duplex communication data of the vehicle-mounted antenna repeater, that is, the preset communication state parameters are the specified duplex communication state of the vehicle-mounted antenna repeater, and also correspond to the reference duplex communication mode of the vehicle-mounted antenna repeater. By performing channel likelihood processing on the duplex communication state parameters and preset communication state parameters, it is easy to determine the degree of difference in the current duplex communication state operation of the vehicle-mounted antenna repeater. The duplex communication status parameters include the duplex input signal strength of the receiving channel of the vehicle-mounted antenna repeater. This receiving channel duplex input signal strength is the corresponding communication signal strength of the receiving channel of the duplexer in the vehicle-mounted antenna repeater. By collecting the receiving channel duplex input signal strength, it is easy to determine the signal strength of the built-in antenna when receiving communication signals from the external antenna. The receiving channel signal loss is the likelihood loss between the receiving channel duplex input signal strength and a preset receiving signal strength. Specifically, the minimum negative logarithmic likelihood loss between the receiving channel duplex input signal strength and the preset receiving signal strength is calculated. The receiving channel signal loss is used to determine the difference in communication signal strength corresponding to the receiving channel of the duplexer in the vehicle-mounted antenna repeater, thereby facilitating the determination of whether the receiving channel signal of the duplexer in the vehicle-mounted antenna repeater is stable.

[0031] Furthermore, based on the duplex communication likelihood, an attenuation failure signal is sent to the channel attenuator to adjust the channel signal strength. This includes: detecting whether the received channel signal loss is greater than a preset received signal loss; when the received channel signal loss is greater than the preset received signal loss, sending an attenuation enable signal to the received channel attenuator to increase the received channel attenuation value. In this embodiment, the duplex communication likelihood is obtained based on the duplex communication state parameters and preset communication state parameters. The duplex communication state parameters are the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication state parameters are the real-time duplex communication state of the vehicle-mounted antenna repeater, and also correspond to the current duplex communication mode of the vehicle-mounted antenna repeater. By collecting the duplex communication state parameters, it is easy to determine the working state of the duplexer in the vehicle-mounted antenna repeater. The preset communication state parameters are the standard full-duplex communication data of the vehicle-mounted antenna repeater, meaning they represent the designated full-duplex communication state of the vehicle-mounted antenna repeater and correspond to its reference full-duplex communication mode. By processing the channel likelihood between the full-duplex communication state parameters and the preset parameters, the degree of difference in the current full-duplex communication state of the vehicle-mounted antenna repeater can be easily determined. After obtaining the full-duplex communication likelihood, the full-duplex communication state of the vehicle-mounted antenna repeater is determined. Then, by sending an attenuation failure signal to the channel attenuator, the attenuation value of the attenuator in the vehicle-mounted antenna repeater is adjusted, facilitating the adjustment of the full-duplex communication signal strength. This stabilizes the communication signal between the vehicle's internal and external antennas, effectively improving the quality of full-duplex communication between the vehicle and its internal and external components. The duplex communication status parameters include the duplex input signal strength of the receiving channel of the vehicle-mounted antenna repeater. This receiving channel duplex input signal strength is the corresponding communication signal strength of the receiving channel of the duplexer in the vehicle-mounted antenna repeater. By collecting the receiving channel duplex input signal strength, it is easy to determine the signal strength of the built-in antenna when receiving communication signals from the external antenna. The receiving channel signal loss is the likelihood loss between the receiving channel duplex input signal strength and a preset receiving signal strength. The receiving channel signal loss is used to determine the difference in communication signal strength corresponding to the receiving channel of the duplexer in the vehicle-mounted antenna repeater, thereby facilitating the determination of whether the receiving channel signal of the duplexer in the vehicle-mounted antenna repeater is stable. If the signal loss in the receiving channel is greater than the preset receiving loss, it indicates that the signal strength of the receiving channel in the duplexer of the vehicle-mounted antenna repeater exceeds the target value. This means that the signal strength in the receiving channel of the vehicle-mounted antenna repeater is too high, which can easily lead to signal distortion. At this time, by sending an attenuation enable signal to the receiving channel attenuator, the attenuation value of the attenuator located in the receiving channel of the vehicle-mounted antenna repeater is increased, so as to reduce the signal strength of the receiving channel and keep the receiving channel signal within a stable strength range.

[0032] In another embodiment, after detecting whether the signal loss of the receiving channel is greater than a preset receiving loss, the method further includes: when the signal loss of the receiving channel is less than or equal to the preset receiving loss, sending an attenuation disabling signal to the receiving channel attenuator to maintain the current attenuation value of the transmitting channel. At this time, the signal strength of the receiving channel of the duplexer in the vehicle-mounted antenna repeater is within a specified signal strength range, which is considered normal and will not cause distortion of the receiving channel signal. The attenuator can simply maintain its current attenuation value.

[0033] In one embodiment, acquiring the duplex communication status parameters of the vehicle-mounted antenna includes acquiring the duplex input signal strength of the transmit channel of the vehicle-mounted antenna repeater. In this embodiment, the duplex communication status parameters are the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication status parameters are the real-time duplex communication status of the vehicle-mounted antenna repeater, and also correspond to the current duplex communication mode of the vehicle-mounted antenna repeater. By acquiring the duplex communication status parameters, it is convenient to determine the working state of the duplexer in the vehicle-mounted antenna repeater. The duplex communication status parameters include the duplex input signal strength of the transmit channel of the vehicle-mounted antenna repeater, which is the communication signal strength corresponding to the transmit channel of the duplexer in the vehicle-mounted antenna repeater. By acquiring the duplex input signal strength of the transmit channel, it is convenient to determine the signal strength of the built-in antenna when transmitting the communication signal of the external antenna. The duplex input signal strength of the transmit channel is acquired by the detector tube in the vehicle-mounted antenna repeater so that it can be detected by the subsequent OPA operational amplifier input to the vehicle MCU. The transmission channel is the channel through which the built-in antenna sends signals to the external antenna.

[0034] Further, channel likelihood processing is performed on the duplex communication state parameters and preset communication state parameters to obtain the duplex communication likelihood quantity, including: calculating the likelihood loss between the duplex input signal strength of the transmit channel and the preset transmit signal strength to obtain the transmit channel signal loss. In this embodiment, the duplex communication state parameters are the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication state parameters are the real-time duplex communication state of the vehicle-mounted antenna repeater, and also correspond to the current duplex communication mode of the vehicle-mounted antenna repeater. By collecting the duplex communication state parameters, it is easy to determine the working state of the duplexer in the vehicle-mounted antenna repeater. The preset communication state parameters are the standard duplex communication data of the vehicle-mounted antenna repeater, that is, the preset communication state parameters are the specified duplex communication state of the vehicle-mounted antenna repeater, and also correspond to the reference duplex communication mode of the vehicle-mounted antenna repeater. By performing channel likelihood processing on the duplex communication state parameters and preset communication state parameters, it is easy to determine the degree of difference in the current duplex communication state operation of the vehicle-mounted antenna repeater. The duplex communication status parameters include the duplex input signal strength of the transmit channel of the vehicle-mounted antenna repeater. This transmit channel duplex input signal strength is the communication signal strength corresponding to the transmit channel of the duplexer in the vehicle-mounted antenna repeater. By collecting the transmit channel duplex input signal strength, it is easy to determine the signal strength of the built-in antenna when transmitting communication signals from the external antenna. The transmit channel signal loss is the likelihood loss between the transmit channel duplex input signal strength and a preset transmit signal strength. Specifically, the minimum negative logarithmic likelihood loss between the transmit channel duplex input signal strength and the preset transmit signal strength is calculated. The transmit channel signal loss is used to determine the difference in communication signal strength corresponding to the transmit channel of the duplexer in the vehicle-mounted antenna repeater, thereby facilitating the determination of whether the transmit channel signal of the duplexer in the vehicle-mounted antenna repeater is stable.

[0035] Furthermore, based on the duplex communication likelihood, an attenuation failure signal is sent to the channel attenuator to adjust the channel signal strength. This includes: detecting whether the signal loss of the transmission channel is greater than a preset transmission loss; when the signal loss of the transmission channel is less than or equal to the preset transmission loss, sending an attenuation failure signal to the transmission channel attenuator to maintain the current attenuation value of the transmission channel. In this embodiment, the duplex communication likelihood is obtained based on the duplex communication state parameters and preset communication state parameters. The duplex communication state parameters are the duplex communication data of the vehicle-mounted antenna repeater, that is, the duplex communication state parameters are the real-time duplex communication state of the vehicle-mounted antenna repeater, and also correspond to the current duplex communication mode of the vehicle-mounted antenna repeater. By collecting the duplex communication state parameters, it is easy to determine the working state of the duplexer in the vehicle-mounted antenna repeater. The preset communication state parameters are the standard full-duplex communication data of the vehicle-mounted antenna repeater, meaning they represent the designated full-duplex communication state of the vehicle-mounted antenna repeater and correspond to its reference full-duplex communication mode. By processing the channel likelihood between the full-duplex communication state parameters and the preset parameters, the degree of difference in the current full-duplex communication state of the vehicle-mounted antenna repeater can be easily determined. After obtaining the full-duplex communication likelihood, the full-duplex communication state of the vehicle-mounted antenna repeater is determined. Then, by sending an attenuation failure signal to the channel attenuator, the attenuation value of the attenuator in the vehicle-mounted antenna repeater is adjusted, facilitating the adjustment of the full-duplex communication signal strength. This stabilizes the communication signal between the vehicle's internal and external antennas, effectively improving the quality of full-duplex communication between the vehicle and its internal and external components. The duplex communication status parameters include the duplex input signal strength of the transmit channel of the vehicle-mounted antenna repeater. This transmit channel duplex input signal strength is the corresponding communication signal strength of the transmit channel of the duplexer in the vehicle-mounted antenna repeater. By collecting the transmit channel duplex input signal strength, it is easy to determine the signal strength of the built-in antenna when transmitting communication signals from the external antenna. The transmit channel signal loss is the likelihood loss between the transmit channel duplex input signal strength and a preset transmit signal strength. The transmit channel signal loss is used to determine the difference in communication signal strength corresponding to the transmit channel of the duplexer in the vehicle-mounted antenna repeater, thereby facilitating the determination of whether the transmit channel signal of the duplexer in the vehicle-mounted antenna repeater is stable. If the transmit channel signal loss is less than or equal to the preset transmit loss, it indicates that the transmit channel signal strength of the duplexer in the vehicle-mounted antenna repeater is within the specified signal strength range, which is considered normal and will not cause distortion of the transmit channel signal. The attenuator can maintain its current attenuation value.

[0036] In another embodiment, after detecting whether the signal loss of the transmission channel is greater than a preset transmission loss, the method further includes: when the signal loss of the transmission channel is greater than the preset transmission loss, sending an attenuation enable signal to the transmission channel attenuator to increase the transmission channel attenuation value. At this time, the transmission channel signal strength of the duplexer in the vehicle-mounted antenna repeater exceeds the target value, indicating that the transmission channel signal strength in the vehicle-mounted antenna repeater is too high, which can easily lead to transmission channel signal distortion. By sending an attenuation enable signal to the transmission channel attenuator, the attenuation value of the attenuator located in the transmission channel of the vehicle-mounted antenna repeater is increased, thereby reducing the transmission channel signal strength and keeping the transmission channel signal within a stable strength range.

[0037] During actual communication between the vehicle's internal and external antennas, the duplexer is in a transmit / receive state for a long time. That is, the receiving and transmitting channels of the antenna repeater are always active. This causes the transmitting channel to request signal usage even when no mobile devices are in use in the vehicle, resulting in the transmitting channel being in an idle state and thus causing excessive power consumption of the antenna repeater.

[0038] The process of obtaining the duplex communication status parameters of the vehicle-mounted antenna repeater previously included: Obtain the transmit drive power of the vehicle-mounted antenna repeater; Detect whether the transmit drive power is greater than or equal to the preset drive power; When the transmit drive power is greater than or equal to the preset drive power, a channel enable signal is sent to the transmit power amplifier.

[0039] In this embodiment, the transmit drive power is the drive power within the transmit channel of the vehicle-mounted antenna repeater, i.e., the transmit drive power is the transmit power of the vehicle-mounted antenna repeater. Specifically, the transmit drive power is obtained by collecting the output power of the drive stage in the vehicle-mounted antenna repeater. The preset drive power is the standard output power of the drive stage in the vehicle-mounted antenna repeater, i.e., the preset drive power is the set operating power required by the transmit channel in the vehicle-mounted antenna repeater. If the transmit drive power is greater than or equal to the preset drive power, it indicates that the power required by the transmit channel of the drive stage in the vehicle-mounted antenna repeater is greater than the set power, i.e., the output power required by the drive stage in the vehicle-mounted antenna repeater exceeds the set value, which indicates that there is a transmission demand. At this time, a channel activation signal is sent to the transmit power amplifier to turn on the power amplifier PA in the transmit channel, thereby facilitating the amplification and transmission of the transmit channel signal. This ensures that the transmit channel is activated when there is a transmission demand, thereby reducing the power consumption of the vehicle-mounted antenna repeater.

[0040] Further, the process includes detecting whether the transmit drive power is greater than or equal to a preset drive power, followed by: When the transmit drive power is less than the preset drive power, the signal strength received by the external antenna of the vehicle-mounted antenna repeater is obtained; Detect whether the signal strength received by the external antenna is less than the preset external signal strength; When the received signal strength of the external antenna is less than the preset external signal strength, a switching antenna signal is sent to the switch controller.

[0041] In this embodiment, the transmit drive power being less than the preset drive power indicates that the power required by the transmit channel of the drive stage in the vehicle-mounted antenna repeater is less than the set power. This means the output power required by the drive stage in the vehicle-mounted antenna repeater is lower than the set value, indicating that there is no transmit demand at this time, and the receive channel maintains communication. The received signal strength of the external antenna is the signal strength received by the internal antenna from the external antenna. If the received signal strength of the external antenna is less than the preset external signal strength, it indicates that the signal strength of the receive channel of the vehicle-mounted antenna repeater is too low, meaning the antenna signal quality input by the currently used external antenna is poor. At this time, a switching antenna signal is sent to the switch controller to switch the used external antenna until the signal quality input by the switched external antenna meets the requirements, thereby improving the communication signal efficiency in the receive channel of the vehicle-mounted antenna repeater.

[0042] In another embodiment, when the signal strength received by the external antenna is greater than or equal to a preset external signal strength, a channel shutdown signal is sent to the transmitting power amplifier.

[0043] In another embodiment, the acquisition of the signal strength received by the external antenna and the corresponding switching of the external antenna are also performed after the transmitting power amplifier is turned on, so as to ensure that the external antenna switching is performed when the transmitting and receiving channels are turned on at the same time, thereby improving the signal quality of the external antenna received in this state.

[0044] All the aforementioned preset variables are set in the database for easy retrieval, and different preset variables are placed in different storage units, i.e., in different storage stacks. Furthermore, the transmit drive power and the signal strength received by the external antenna can be acquired by the corresponding processor, for example, through the detector and driver of the duplex communication acquisition module.

[0045] In one embodiment, this disclosure also relates to a vehicle-mounted antenna signal communication device, which employs the vehicle-mounted antenna signal communication method described in any of the above embodiments. The vehicle-mounted antenna signal communication device includes: a duplex communication acquisition module, a duplex communication processing module, and an attenuation mode control module. The duplex communication acquisition module is used to acquire duplex communication status parameters of the vehicle-mounted antenna repeater. The duplex communication processing module is used to perform channel likelihood processing on the duplex communication status parameters and preset communication status parameters to obtain a duplex communication likelihood value. The attenuation mode control module is used to send an attenuation failure signal to the channel attenuator according to the duplex communication likelihood value to adjust the channel signal strength.

[0046] In this embodiment, after the duplex communication acquisition module collects the duplex communication status parameters, it determines the communication status changes of the vehicle-mounted antenna repeater under the current duplex communication mode. Then, the duplex communication processing module compares the duplex communication status with the standard communication status to determine the degree of difference in the duplex communication status changes of the vehicle-mounted antenna repeater. Finally, the attenuation mode control module adjusts the signal attenuation mode in the duplex communication according to the above-mentioned degree of difference, so as to provide feedback adjustment to the working conditions of the channel attenuator, thereby stabilizing the communication signal between the internal and external antennas of the vehicle and effectively improving the duplex communication quality between the internal and external antennas of the vehicle.

[0047] In another embodiment, the vehicle-mounted antenna signal communication device further includes an external antenna switch control module, which is used to switch the number and type of external antennas that are connected. Figure 4 In the first embodiment shown, the external antenna switch control module includes a single-pole double-throw (SPDT) switch, a duplexer, and two quadplexers. The two switching terminals of the SPDT switch are respectively connected to two external antennas. The common terminal of the SPDT switch is connected to the first transceiver terminal of the duplexer. The two second transceiver terminals of the duplexer are respectively connected to the first transceiver terminal of one of the quadplexers. The two second transceiver terminals of each quadplexer are used to transmit and receive antenna signals in two frequency bands.

[0048] In another embodiment, the two second transceiver ends of one of the quadrupoles are used to transmit and receive antenna signals in bands B1 and B3, respectively, while the two second transceiver ends of the other quadrupole are used to transmit and receive antenna signals in bands B28 and B3, respectively. Using this external antenna switch control module, the insertion loss can be controlled to less than 3.55 dB, and the noise figure can be controlled to within 5 dB.

[0049] In another embodiment, such as Figure 5In the second embodiment shown, the external antenna switch control module includes a single-pole double-throw (SPDT) switch, a double-pole double-throw (DPDT) switch, four duplexers, and one quadplexer. Each switching terminal of the DPDT switch is connected to the first transceiver terminal of one of the duplexers. The second transceiver terminals of the two duplexers are each connected to an external antenna, and the third transceiver terminals of the two duplexers are each connected to a switching terminal of the SPDT switch. The common terminal of the SPDT switch is connected to the first transceiver terminal of the quadplexer. The two second transceiver terminals of the quadplexer are used to receive antenna signals from two frequency bands, for example, B1 and B3 frequency bands. The second transceiver terminals of the other two duplexers are used to receive antenna signals from two other frequency bands, for example, B8 and B28 frequency bands. Furthermore, the insertion loss of this external antenna switch control module can be controlled to be less than 4.25 dB, and the noise figure can be controlled to within 5 dB.

[0050] Compared to existing switch control modules, the two external antenna switch control modules described above offer advantages such as... Figure 6 Scheme 3, as shown, has a loss ranging from 3.85 to 7.45, which makes Schemes 1 and 2 have even lower loss, resulting in a lower noise figure and ensuring communication quality during external antenna switching. For details on the loss of the three schemes, please refer to the appendix. Figure 7 See Table 1.
