[0034] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] In the related art, different user identification cards use different antennas for signal reception. In the dual-card communication scenario, multiple groups of antenna reception need to be divided. After the first user identification card uses the antenna with a better radiation environment, the second user identification card can only choose to use the remaining antennas. This causes some of the multiple user identification cards to have poor signal quality due to the poor radiation environment of the antenna used, which in turn affects the signal function corresponding to the user identification card. For this reason, it is often necessary to set up more antennas for use by other user identification cards.

[0036] In order to solve the above technical problems, according to an embodiment of the present disclosure, a radio frequency component is provided, which includes: a transceiver, the transceiver includes a port group, the port group includes a first port and a second port, the first port is used to communicate with a first user identity card, and the second port is used to communicate with a second user identity card; an antenna; a switch module, used to select the first port and / or the second port in the port group to be connected to the antenna for communication, and enable the antenna to communicate with the first user identity card and / or the second user identity card through the switched port.

[0037] The present disclosure connects an antenna to a transceiver having multiple ports, and enables the antenna to be connected to a first user identity card and a second user identity card through a first port and a second port, respectively, so that the first user identity card and the second user identity card can share the same antenna for signal reception, thereby realizing multiplexing of antennas by multiple user identity cards, thereby eliminating the need for additional antennas and achieving the effect of reducing costs.

[0038] It can be understood that the radio frequency component involved in the present disclosure can be applicable to any terminal listed below.

[0039] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0040] Figure 1 The diagram is a schematic structural diagram of a radio frequency component according to an exemplary embodiment.

[0041] In some embodiments, Figure 1 As shown, a radio frequency component may include: a transceiver 60, an antenna and a switch module.

[0042] The user identification card can be used as a network key to enable electronic devices to communicate data.

[0043] The user identification card may include a first user identification card and a second user identification card.

[0044] The transceiver 60 may convert the RF signal received by the RF component into a digital signal for processing by the RF component, and the transceiver 60 may also convert the digital signal into a RF signal for transmission by the RF component.

[0045] The transceiver 60 may include a port group, which may include a first port 61 and a second port 62, and support the first port and the second port to receive simultaneously, wherein the first port 61 can be used to communicate with a first user identity card, and the second port 62 can be used to communicate with a second user identity card.

[0046] The antenna may be a component in a radio frequency component for radiating or receiving signals. The antenna may communicate with the first user identification card through the first port 61 of the transceiver 60, and the antenna may communicate with the second user identification card through the second port 62 of the transceiver 60. The antenna may transmit a function signal to the user identification card.

[0047] The switch module can be used to select the first port 61 in the port group to communicate with the antenna, and enable the antenna to communicate with the first user identification card through the first port 61 .

[0048] The switch module can be used to select the second port 62 in the port group to communicate with the antenna, and enable the antenna to communicate with the second user identification card through the second port 62 .

[0049] The switch module can also simultaneously select the first port 61 and the second port 62 in the port group to communicate with the antenna, and enable the antenna to communicate with the first user identification card through the first port 61 and the antenna to communicate with the second user identification card through the second port 62.

[0050] By connecting the antenna to a port group having multiple ports, and enabling the antenna to communicate with the first user identity card and the second user identity card through the first port 61 and the second port 62 respectively, the first user identity card and the second user identity card can share the same antenna for signal reception, thereby achieving multiplexing of the antenna by multiple user identity cards, thereby eliminating the need for additional antennas and achieving the effect of reducing costs.

[0051] Exemplarily, the antenna may include a first antenna 51. The switch module may include a first switch module 21

[0052] The first switch module 21 can be arranged between the first antenna 51 and the transceiver 60. The first switch module 21 can be used to change the connection relationship between the first antenna 51 and the first port 61 and the second port 62 of the transceiver 60, thereby changing the connection relationship between the first antenna 51 and the first user identity card and the second user identity card.

[0053] The first switch module 21 can control the first antenna 51 to connect to the first user identification card through the first port 61, that is, the first switch module 21 can connect the first antenna 51 to the first port 61, thereby connecting the first antenna 51 to the first user identification card. The first user identification card can receive the function signal from the first antenna 51.

[0054] The first switch module 21 can also disconnect the first antenna 51 from the first port 61, thereby disconnecting the first antenna 51 from the first user identification card. The first user identification card and the first antenna 51 are disconnected, and the first antenna 51 no longer transmits function signals to the first user identification card.

[0055] The first switch module 21 controls the first antenna 51 to connect to the second user identification card through the second port 62, that is, the second switch module 22 can connect the first antenna 51 to the second port 62, thereby connecting the first antenna 51 to the second user identification card. The second user identification card can receive the function signal from the first antenna 51.

[0056] The second switch module 22 can also disconnect the first antenna 51 from the second port 62, thereby disconnecting the first antenna 51 from the second user identification card. The second user identification card and the first antenna 51 are disconnected, and the first antenna 51 no longer transmits function signals to the second user identification card.

[0057] The first switch module 21 can also connect the first antenna 51 to the first port 61, and the first antenna 51 is also connected to the second port 62, so that the first user identification card can receive the function signal from the first antenna 51, and the second user identification card can also receive the function signal from the first antenna 51. That is, the first user identification card and the second user identification card can share the first antenna 51 for signal reception.

[0058] The connection relationship between the first antenna 51 and the first port 61 and the second port 62 is switched by the first switch module 21, and the first antenna 51 is connected to the first user identity identification card and the second user identity identification card through the first port 61 and the second port 62 respectively, so that the first user identity identification card and the second user identity identification card can share the antenna for signal reception, thereby realizing the multiplexing of the first user identity identification card and the second user identity identification card for the same antenna. On the one hand, the first user identity identification card and the second user identity identification card can both select antennas with better performance for signal reception, and on the other hand, the number of antennas required for multiple user identity identification cards can be reduced, thereby achieving the effect of reducing costs.

[0059] In some embodiments, the switch module may be a multi-pole multi-throw switch.

[0060] In some embodiments, Figure 1 As shown, the radio frequency component includes an amplifier, which can be arranged between the antenna and the user identification card.

[0061] The amplifier can be used to adjust the signal strength transmitted from the antenna to the user identification card, so that the transceiver 60 and the user identification card can further process the signal. For example, the amplifier can adjust the power of the signal transmitted from the antenna to the user identification card.

[0062] After the first user identity identification card and the second user identity identification card are configured to share the same antenna, the signal strength of the functional signal transmitted by the antenna to the user identity identification card will be attenuated. By configuring the signal strength of the functional signal to a preset value through the amplifier, the signal strength of the functional signal transmitted by the antenna to the first user identity identification card and the second user identity identification card can be maintained within a range that enables the first user identity identification card and the second user identity identification card to work normally.

[0063] Furthermore, under different working conditions of the RF component, different signal strengths of the functional signal have different signal qualities. The amplifier can improve the signal quality of the functional signal received by the transceiver 60 and the user identification card by configuring the signal strength of the functional signal to a signal strength with higher signal quality, that is, configuring the signal strength of the functional signal to a preset value, thereby improving the working stability of the RF component.

[0064] In some embodiments, the amplifier may be a low noise amplifier. The low noise amplifier may be an amplifier with a very low noise coefficient. When amplifying weak signals, the noise of the amplifier itself interferes with the weak signals seriously, so the use of a low noise amplifier can reduce such noise to improve the signal-to-noise ratio of the output signal.

[0065] In some embodiments, the amplifier may include an external amplifier, which may be disposed between the antenna and the switch module. The antenna may transmit a functional signal to the user identification card, and the external amplifier may change the signal strength of the functional signal.

[0066] The external amplifier can be used to adjust the signal strength of the functional signal transmitted by the antenna to the first user identification card and the second user identification card, so that the transceiver 60 and the user identification card can further process the signal. For example, the amplifier can adjust the power of the signal transmitted by the antenna to the user identification card.

[0067] After the first user identity identification card and the second user identity identification card are configured to share the same antenna, the signal strength of the functional signal transmitted by the antenna to the user identity identification card will be lost and attenuated. By configuring the signal strength of the functional signal to a preset value through the amplifier, the signal strength of the functional signal transmitted by the antenna to the first user identity identification card and the second user identity identification card can be maintained within a range that enables the first user identity identification card and the second user identity identification card to work normally.

[0068] Furthermore, under different working states of the RF component, different signal strengths of the functional signal have different signal qualities. The amplifier can improve the signal quality of the functional signal received by the transceiver 60 and the user identity card from the antenna by configuring the signal strength of the functional signal to a signal strength with higher signal quality, that is, configuring the signal strength of the functional signal to a preset value, thereby improving the working stability of the RF component.

[0069] For example, Figure 1 As shown, the amplifier may include a first external amplifier 31, which may be disposed between the first antenna 51 and the first switch module 21, and the first antenna 51 may transmit a first function signal to the user identity card, and the first external amplifier 31 may change the signal strength of the first function signal.

[0070] The first external amplifier 31 can be used to adjust the signal strength of the functional signal transmitted by the first antenna 51 to the first user identity card and the second user identity card, so that the transceiver 60 and the user identity card can further process the signal. Exemplarily, the amplifier can adjust the power of the signal transmitted by the antenna to the user identity card.

[0071] After the first user identity identification card and the second user identity identification card are configured to share the first antenna 51, the signal strength of the functional signal transmitted by the first antenna 51 to the user identity identification card will be attenuated. By configuring the signal strength of the functional signal to a preset value through an external amplifier, the signal strength of the functional signal transmitted by the first antenna 51 to the first user identity identification card and the second user identity identification card can be maintained within the range that enables the first user identity identification card and the second user identity identification card to operate normally.

[0072] Furthermore, under different working states of the RF component, different signal strengths of the functional signal have different signal qualities. The external amplifier can improve the signal quality of the functional signal received by the transceiver 60 and the user identity card from the first antenna 51 by configuring the signal strength of the functional signal to a signal strength with higher signal quality, that is, configuring the signal strength of the functional signal to a preset value, thereby improving the working stability of the RF component.

[0073] In some embodiments, the amplifier may include a built-in amplifier group, and the built-in amplifier group may be disposed in the transceiver 60. The built-in amplifier group may include a first built-in amplifier and a second built-in amplifier.

[0074] The first built-in amplifier may be disposed between the first port 61 and the first user identification card, and the second built-in amplifier may be disposed between the second port 62 and the second user identification card.

[0075] The function signal may include a first sub-function signal transmitted to the first user identification card and a second sub-function signal transmitted to the second user identification card.

[0076] When the working modes of the first user identity card and the second user identity card are different, the gain amplitudes required by the amplifier to be applied by the function signal transmitted to the first user identity card and the function signal transmitted to the second user identity card are different. Therefore, the first built-in amplifier arranged between the first port 61 and the first user identity card can change the signal strength of the first sub-function signal alone, thereby improving the strength of the first sub-function signal received by the first user identity card, and the second built-in amplifier can change the signal strength of the first sub-function signal.

[0077] The first built-in amplifier and the second built-in amplifier may also be used to compensate for the different functional signal attenuation between the transmission path from the antenna to the first user identification card and the transmission path from the antenna to the second user identification card due to component differences or circuit design differences.

[0078] In the process of gaining the first functional signal, the first functional signal is firstly gained by the external amplifier. When the gain generated by the external amplifier on the functional signal makes the signal quality of the first sub-functional signal and the signal quality of the second sub-functional signal meet the signal quality requirements, the gain effect of the first built-in amplifier and the second built-in amplifier is no longer adjusted. Reducing the number of amplifiers to be adjusted can reduce the clutter interference received during the transmission of the functional signal.

[0079] Exemplarily, when the gain of the first external amplifier 31 for the functional signal cannot make the signal quality of the first sub-function signal and the second sub-function signal meet the requirements, the gain effect of the first built-in amplifier and the gain effect of the second built-in amplifier are adjusted to make the signal quality of the first sub-function signal and the signal quality of the second sub-function signal meet the corresponding signal quality requirements.

[0080] In the process of gaining the functional signal, the first external amplifier 31 firstly gains the functional signal. When the gain generated by the first external amplifier 31 on the functional signal makes the signal quality of the first sub-functional signal and the signal quality of the second sub-functional signal meet the signal quality requirements, the gain effect of the first built-in amplifier and the second built-in amplifier is no longer adjusted. Reducing the number of amplifiers to be adjusted can reduce the clutter interference received during the transmission of the functional signal.

[0081] When the gain of the first external amplifier 31 for the functional signal cannot make the signal quality of the first sub-function signal and the second sub-function signal meet the requirements, the gain effect of the first built-in amplifier and the gain effect of the second built-in amplifier are adjusted to make the signal quality of the first sub-function signal and the signal quality of the second sub-function signal meet the corresponding signal quality requirements.

[0082] The first built-in amplifier and the second built-in amplifier can also be used to compensate for the link loss caused by the first switch module 21, and the specific adjustment gain can be changed according to the link loss situation.

[0083] In some embodiments, when the first switch module 21 controls the first antenna 51 to connect to the first user identification card, the amplifier configures the signal strength of the functional signal to a first preset value. When the signal strength of the functional signal is the first preset value, the signal quality of the functional signal can meet the signal quality required for the normal operation of the first user identification card.

[0084] The first preset value may be a signal strength value corresponding to the best signal quality of the functional signal when the first user identification card receives the functional signal within the adjustment range of the signal strength of the functional signal by the amplifier.

[0085] When the first switch module 21 controls the first antenna 51 to connect to the second user identification card, the amplifier configures the signal strength of the function signal to the second preset value. When the signal strength of the function signal is the second preset value, the signal quality of the function signal can meet the signal quality required for the normal operation of the second user identification card.

[0086] The second preset value may be a signal strength value corresponding to the best signal quality of the functional signal when the second user identification card receives the functional signal within the adjustment range of the signal strength of the functional signal by the amplifier.

[0087] When the first switch module 21 controls the first antenna 51 to connect to the first user identification card and the second user identification card at the same time, the amplifier configures the signal strength of the function signal to be a third preset value. When the signal strength of the function signal is the third preset value, the signal quality of the first sub-function signal can meet the signal quality required for the normal operation of the first user identification card, and the signal quality of the second sub-function signal can meet the signal quality required for the normal operation of the second user identification card.

[0088] The third preset value may be a signal strength value corresponding to the best signal quality of the first sub-function signal and the best signal quality of the second sub-function signal when the first user identity card and the second user identity card simultaneously receive the function signal within the adjustment range of the amplifier for the signal strength of the function signal.

[0089] In some embodiments, the signal strength of the first sub-function signal can be configured to a fourth preset value by additionally adjusting the first built-in amplifier based on the first external amplifier 31. The signal strength of the second sub-function signal can be configured to a fifth preset value by additionally adjusting the second built-in amplifier based on the first external amplifier 31.

[0090] Therefore, the signal quality of the first sub-function signal and the signal quality of the second sub-function signal can be specifically adjusted according to different design configurations.

[0091] In some embodiments, when the first user identity card and the second user identity card have the same configuration, the first preset value and the second preset value may also be equal.

[0092] In some embodiments, the preset value can be obtained by the following steps: obtaining a data set corresponding to the signal strength of the functional signal and the signal quality of the functional signal; using the signal strength corresponding to the target signal quality in the data set as the first preset value, the second preset value or the third preset value. The target signal quality can be the signal quality with the best signal quality in the data set.

[0093] Exemplarily, when the first switch module 21 controls the first antenna 51 to connect to the first user identification card, a first data group corresponding to the signal strength of the functional signal and the signal quality of the functional signal is obtained. The signal strength and signal quality in the first data group are interpolated and simulated to obtain a corresponding relationship curve between the signal strength and signal quality of the functional signal. The signal quality with the best signal quality in the relationship curve is set as the target signal quality, and the signal strength corresponding to the target signal quality is the first preset value.

[0094] When the first switch module 21 controls the first antenna 51 to connect to the second user identification card, a second data group corresponding to the signal strength of the functional signal and the signal quality of the functional signal is obtained. The signal strength and signal quality in the second data group are interpolated and simulated to obtain a corresponding relationship curve between the signal strength and signal quality of the functional signal. The signal quality with the best signal quality in the relationship curve is set as the target signal quality, and the signal strength corresponding to the target signal quality is the second preset value.

[0095] When the first switch module 21 controls the first antenna 51 to connect to the first user identification card and the second user identification card at the same time, a third data group corresponding to the signal strength of the functional signal and the signal quality of the functional signal is obtained. The signal strength and signal quality in the third data group are interpolated and simulated to obtain a corresponding relationship curve between the signal strength and signal quality of the functional signal. The signal quality with the best signal quality in the relationship curve is set as the target signal quality, and the signal strength corresponding to the target signal quality is the third preset value.

[0096] By adjusting the signal strength of the functional signal, the signal quality of the functional signal is changed to the target signal quality, thereby improving the signal quality received by the user identification card and improving the receiving performance of the radio frequency component.

[0097] In some embodiments, Figure 1 As shown, the radio frequency component may include: a second antenna 52 and a second switch module 22 .

[0098] The second switch module 22 may be disposed between the second antenna 52 and the first switch module 21.

[0099] The second switch module 22 can control the second antenna 52 to connect to the first user identification card through the first port 61, that is, the second switch module 22 can connect the second antenna 52 to the first port 61, thereby connecting the second antenna 52 to the first user identification card. The first user identification card can receive the function signal from the second antenna 52.

[0100] The second switch module 22 can also disconnect the second antenna 52 from the first port 61, thereby disconnecting the second antenna 52 from the first user identification card. The first user identification card and the second antenna 52 are disconnected, and the second antenna 52 no longer transmits function signals to the first user identification card.

[0101] The second switch module 22 controls the second antenna 52 to connect to the second user identification card through the second port 62, that is, the second switch module 22 can connect the second antenna 52 to the second port 62, thereby connecting the second antenna 52 to the second user identification card. The second user identification card can receive the function signal from the second antenna 52.

[0102] The second switch module 22 can also disconnect the second antenna 52 from the second port 62, thereby disconnecting the second antenna 52 from the second user identification card. The second user identification card and the second antenna 52 are disconnected, and the second antenna 52 no longer transmits function signals to the second user identification card.

[0103] The second switch module 22 can also connect the second antenna 52 to the first port 61, and the second antenna 52 is also connected to the second port 62, so that the first user identification card can receive the function signal from the second antenna 52, and the second user identification card can also receive the function signal from the second antenna 52. That is, the first user identification card and the second user identification card can share the second antenna 52 for signal reception.

[0104] The connection relationship between the second antenna 52 and the first port 61 and the second port 62 is switched by the second switch module 22, and the second antenna 52 is connected to the first user identity identification card and the second user identity identification card through the first port 61 and the second port 62 respectively, so that the first user identity identification card and the second user identity identification card can share the second antenna 52 for signal reception, thereby realizing the multiplexing of the second antenna 52 by the first user identity identification card and the second user identity identification card. On the one hand, the first user identity identification card and the second user identity identification card can both select antennas with better performance for signal reception, and on the other hand, the number of antennas required for multiple user identity identification cards can be reduced, thereby achieving the effect of reducing costs.

[0105] In some embodiments, the amplifier may include a second external amplifier 32, which is disposed between the second antenna 52 and the second switch module 22. The second antenna 52 transmits a second function signal to the user identification card, and the amplifier changes the signal strength of the second function signal.

[0106] The second external amplifier 32 can be used to adjust the signal strength of the functional signal transmitted by the second antenna 52 to the first user identity card and the second user identity card, so that the transceiver 60 and the user identity card can further process the signal. Exemplarily, the amplifier can adjust the power of the signal transmitted by the antenna to the user identity card.

[0107] After the first user identity identification card and the second user identity identification card are configured to share the second antenna 52, the signal strength of the functional signal transmitted by the second antenna 52 to the user identity identification card will be attenuated. By configuring the signal strength of the functional signal to a preset value through the amplifier, the signal strength of the functional signal transmitted by the second antenna 52 to the first user identity identification card and the second user identity identification card can be maintained within a range that enables the first user identity identification card and the second user identity identification card to work normally.

[0108] Furthermore, under different working conditions of the RF component, different signal strengths of the functional signal have different signal qualities. The amplifier can improve the signal quality of the functional signal received by the transceiver 60 and the user identity card from the second antenna 52 by configuring the signal strength of the functional signal to a signal strength with higher signal quality, that is, configuring the signal strength of the functional signal to a preset value, thereby improving the working stability of the RF component.

[0109] In some embodiments, the first antenna 51 may receive a first frequency band signal, and the first antenna 51 may transmit a first function signal corresponding to the first frequency band signal to the first user identity card and the second user identity card.

[0110] The second antenna 52 can receive the second frequency band signal, and the second antenna 52 can transmit the second function signal corresponding to the second frequency band signal to the first user identification card and the second user identification card.

[0111] By making the first user identification card and the second user identification card use the first antenna 51 and the second antenna 52 to receive signals at the same time, the first user identification card and the second user identification card can share multiple antennas to receive data, so that the radio frequency component can achieve multiple inputs and multiple outputs, increase the data throughput of the radio frequency component, and improve the performance of the radio frequency component.

[0112] In some embodiments, the RF component may include: a receiving module, which may include a filter and a main switch. Figure 1 As shown, the radio frequency module may include a first receiving module 11

[0113] One end of the filter can be connected to the antenna, and the other end of the filter can be connected to the switch module. The filter is used to filter the clutter in the signal received by the antenna to improve the signal quality of the functional signal.

[0114] The main switch can be arranged between the antenna and the switch module, and the main switch can control the conduction or disconnection between the antenna and the switch module, that is, when the main switch is disconnected, the antenna is disconnected from the communication with both the first user identification card and the second user identification card.

[0115] In some embodiments, there may be multiple antennas, multiple switch modules, multiple external amplifiers, multiple port groups, and multiple built-in amplifier groups.

[0116] Among them, multiple antennas, multiple switch modules, multiple external amplifiers, multiple port groups and multiple built-in amplifier groups correspond to each other one by one.

[0117] For example, Figure 1 As shown, the RF component may also include: a third antenna 53, a fourth antenna 54, a third switch module 23, a fourth switch module 24, a third external amplifier 33, a fourth external amplifier 34, a second receiving module 12, a third receiving module 13 and a fourth receiving module 14.

[0118] The connection relationship and function thereof are the same or similar to those in the above-mentioned embodiment and will not be described in detail here.

[0119] Based on the same concept, an embodiment of the present disclosure also provides a radio frequency device.

[0120] The radio frequency device may be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a message transceiver device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, and a wearable device such as a watch or a bracelet, etc., and may be any electronic device having a radio frequency component. In the following description, a mobile phone is used as an example, but the present disclosure is not limited thereto.

[0121] Figure 2 The diagram is a schematic structural diagram of a radio frequency device according to an exemplary embodiment.

[0122] In some embodiments, Figure 2 As shown, a first antenna 51, a second antenna 52, a third antenna 53 and a fourth antenna 54 may be included, and the electronic device may support a multiple-input multiple-output antenna solution, and four groups of antennas may receive data simultaneously.

[0123] The first antenna 51, the second antenna 52, the third antenna 53 and the fourth antenna 54 can be distributed in different positions of the electronic device. Therefore, under different working conditions and radiation environments, the first antenna 51, the second antenna 52, the third antenna 53 and the fourth antenna 54 can have different radiation qualities. The first user identity card and the second user identity card can select antennas with good radiation conditions for wireless data reception according to the specific radiation conditions of the antennas.

[0124] In some embodiments, the RF component may support reception of multiple frequency bands. For example, the RF component may support 2G frequency band, 3G frequency band, 4G frequency band and 5G frequency band.

[0125] This solution uses an amplifier automatic gain control algorithm and a link loss automatic compensation algorithm to achieve optimal reception performance under dual cards.

[0126] In some embodiments, when the electronic device is in a dual-card communication working scenario, the first user identity card and the second user identity card are in different network states, and the gain of the link corresponding to the first port 61 and the gain of the link corresponding to the second port 62 can be dynamically adjusted through the amplifier, so that the signal quality of the functional signals received by multiple user identity cards can be at a better level at the same time.

[0127] In some embodiments, the amplifier automatic gain control algorithm can dynamically adjust the gain of the built-in amplifier in the transceiver 60 and the gain of the external amplifier in real time, so that the signal quality of the functional signals received by multiple user identification cards can be at a relatively good level at the same time.

[0128] In some embodiments, in order to ensure that the signals of both links can achieve good signal quality, the transceiver 60 can automatically compensate for the link loss caused by multiple opening of the switch module when the two cards work simultaneously through an internal algorithm, thereby improving the link reception performance of the RF component.

[0129] In some embodiments, the data set required for the built-in amplifier gain of the transceiver 60 and the amplifier gain adjustment algorithm set in the link can be obtained by the following method.

[0130] First, fix the gain of the built-in amplifier of the transceiver 60. Connect the switch modules to the single ports of the transceiver 60 for calibration respectively, and obtain two sets of data correspondences between different signal levels and amplifier gain levels set in the link, which are recorded as data group a and data group b.

[0131] Then the switch module is connected to two ports of the transceiver 60 at the same time, and the two receiving links are calibrated when working on one antenna at the same time, to obtain two sets of data correspondences between signal levels and amplifier gain levels, which are recorded as data set c and data set d.

[0132] Finally, data set a and data set b are interpolated and simulated with data set c and data set d to obtain data set e.

[0133] In different working frequency bands, the built-in amplifier gain of the new transceiver 60 can be re-fixed, and the above steps are repeated to record multiple groups of calibration data to obtain data clusters.

[0134] In some embodiments, when two user identification cards of an electronic device work in different modes at the same time, the link insertion loss caused by multiple opening of the switch module can be adjusted and compensated by finding the data group e corresponding to the scene, and combining it with the static data during link calibration. The data difference curve calculated during dual-card operation and single-channel calibration is used as a benchmark, and the gain of the amplifier is adjusted in real time according to the working frequency band, so that the link can accurately adjust the compensation data when a single card is working or when dual cards are working.

[0135] In some embodiments, the gain of the amplifier noise floor amplifier set in the link is adjusted first. When the signal quality is poor and the insertion loss of the switch module is large, the gain of the built-in amplifier built into the transceiver 60 is adjusted.

[0136] In some embodiments, when the electronic device is in a dual-card working mode and the network condition of the electronic device is poor, the electronic device can dynamically adjust the amplifier gain in real time according to the data group c, the data d and the data group e, so that the amplifier and the built-in amplifier gain are increased, thereby amplifying the signals received by the two links; when the user uses a better network condition, the transceiver 60 will reduce the amplifier and the built-in amplifier gain, thereby reducing the power consumption of the RF component while maintaining a certain signal quality, and improving the endurance of the electronic device.

[0137] Based on the same concept, an embodiment of the present disclosure also provides a control method for a radio frequency component.

[0138] Figure 3 It is a flowchart of a control method according to an exemplary embodiment.

[0139] In some embodiments, the control method of the radio frequency component may include the following steps:

[0140] S10: in response to monitoring the presence of the first user identification card and / or the second user identification card communicating with the transceiver in the radio frequency component;

[0141] S20: Selecting, through a switch module in the radio frequency component, a first port and / or a second port in a port group included in the transceiver to communicate with an antenna in the radio frequency component;

[0142] S30: Transmitting the signal received by the antenna to the first user identification card and / or the second user identification card through the first port and / or the second port.

[0143] In the embodiment of the present disclosure, when the first user identity card or the second user identity card communicates with the transceiver in the radio frequency component, it means that the first user identity card or the second user identity card needs to use the antenna of the radio frequency component, and the switch module connects the antenna and the corresponding port according to the communication result between the user identity card and the transceiver.

[0144] After the first user identification card communicates with the transceiver, the switch module can select the first port and the antenna of the radio frequency component so that the antenna can communicate with the first user identification card through the first port.

[0145] After the second user identification card communicates with the transceiver, the switch module can select to connect the second port with the antenna of the RF component, so that the antenna can communicate with the second user identification card through the second port.

[0146] After the first user identity card communicates with the transceiver, the switch module can select the first port and the antenna of the RF component so that the antenna can communicate with the first user identity card through the first port and the antenna can also communicate with the second user identity card through the second port at the same time.

[0147] Through the above control method, the first port and the second port can reuse the same antenna at the same time, so that the first port and the second port can simultaneously select and share the antenna that meets the communication requirements or has the best antenna performance, thereby improving the signal reception level corresponding to the first function card and the second function card. In addition, there is no need to add additional antennas for additional function cards, thereby achieving the effect of reducing costs.

[0148] Figure 4 It is a flowchart of a control method according to an exemplary embodiment.

[0149] In some embodiments, the control method of the radio frequency component may include the following steps:

[0150] S10: in response to monitoring the presence of the first user identification card and the second user identification card communicating with the transceiver in the radio frequency component;

[0151] S20: Selecting, through a switch module in the radio frequency component, a first port and / or a second port in a port group included in the transceiver to communicate with an antenna in the radio frequency component;

[0152] S31: Determine the target frequency band and target port currently used for signal transmission;

[0153] S32: determining a target external amplifier gain level matching a target port and a target frequency band in a preset data group, wherein the preset data group includes a correspondence between ports, frequency bands, signal levels, and external amplifier gain levels when different ports in the port group are connected to an antenna;

[0154] S33: Based on the target external amplifier gain level, transmit the signal received by the antenna to the first user identification card and / or the second user identification card through the target port.

[0155] In the embodiment of the present disclosure, when the first user identity card or the second user identity card communicates with the transceiver in the radio frequency component, it means that the first user identity card or the second user identity card needs to use the antenna of the radio frequency component, and the switch module connects the antenna and the corresponding port according to the communication result between the user identity card and the transceiver.

[0156] Get the target port and target frequency band used by the antenna to transmit data to the user identification card.

[0157] The target port and the target frequency band can be used to perform data matching in a preset data group.

[0158] The preset data group may include the corresponding relationship between the ports, frequency bands, signal levels and external amplifier gain levels when different ports in the port group are connected to the antenna.

[0159] Furthermore, the external amplifier gain level corresponding to the target port and the target frequency band, ie, the target external amplifier gain level, can be obtained in the preset data group through the target port and the target frequency band.

[0160] The gain level of the external amplifier is adjusted to a target external amplifier gain level, and the signal received by the antenna can be transmitted to the user identification card through the target port, and the signal strength can reach a signal strength that meets normal working requirements under the gain of the external amplifier.

[0161] The above control method allows the external amplifier to reuse the same antenna at the first port and the second port at the same time, so that the first port and the second port can simultaneously select to share the antenna that meets the communication requirements or has the best antenna performance, and can also make the signal strength corresponding to the user identity card reach the signal strength that meets the normal working requirements, thereby improving the signal reception level corresponding to the first function card and the second function card, and improving the working stability of the RF component.

[0162] Figure 5 It is a flowchart of a control method according to an exemplary embodiment.

[0163] In some embodiments, the preset data group can be predetermined in the following manner:

[0164] S41: Acquire a first data group, a second data group, a third data group, and a fourth data group;

[0165] S42: performing interpolation simulation on the first data group, the second data group, the third data group and the fourth data group to obtain a fifth data group;

[0166] S43: Determine the fifth data group as the preset data group,

[0167] The first data group includes a correspondence between the first signal level and the external amplifier gain level in a plurality of different frequency bands when the switch module selects the first port to be connected to the antenna;

[0168] The second data group includes the correspondence between the second signal level and the external amplifier gain level in multiple different frequency bands when the switch module selects the second port to be connected to the antenna;

[0169] The third data group includes the correspondence between the third signal level and the external amplifier gain level in multiple different frequency bands when the switch module selects the first port and the second port to be connected to the antenna;

[0170] The fourth data group includes corresponding relationships between fourth signal levels and external amplifier gain levels in multiple frequency bands when the switch module selects the first port and the second port to be connected to the antenna.

[0171] When determining the preset data group, the switch module can first be connected to the first port and the second port of the radio frequency transceiver respectively, and the signal strength at the ports in different working frequency bands can be monitored, thereby obtaining a first data group including the corresponding relationship between the signal level at the first port and the gain level of the external amplifier and a second data group including the corresponding relationship between the signal level at the second port and the gain level of the external amplifier.

[0172] The switch module is connected to the first port and the second port of the transceiver at the same time, and the signal strength at the ports in different working frequency bands is monitored, so as to obtain a third data group including the corresponding relationship between the signal level at the first port and the gain level of the external amplifier and a fourth data group including the corresponding relationship between the signal level at the second port and the gain level of the external amplifier.

[0173] Interpolation simulation is performed on the first data group, the second data group, the third data group, and the fourth data group to obtain a fifth data group.

[0174] Figure 6 It is a flowchart of a control method according to an exemplary embodiment.

[0175] In some embodiments, the control method of the radio frequency component may include the following steps:

[0176] S10: in response to monitoring the presence of the first user identification card and the second user identification card communicating with the transceiver in the radio frequency component;

[0177] S20: Selecting, through a switch module in the radio frequency component, a first port and / or a second port in a port group included in the transceiver to communicate with an antenna in the radio frequency component;

[0178] S31: Determine the target frequency band and target port currently used for signal transmission;

[0179] S32: determining a target external amplifier gain level matching a target port and a target frequency band in a preset data group, wherein the preset data group includes a correspondence between ports, frequency bands, signal levels, and external amplifier gain levels when different ports in the port group are connected to an antenna;

[0180] S331: In response to the target port including the first port and the second port, determining a first link insertion loss and a second link insertion loss, the first link insertion loss being a signal link loss when connected to the antenna through the first port, and the second link insertion loss being a signal link loss when connected to the antenna through the second port;

[0181] S332: compensating for the first link insertion loss based on the first data group after interpolation simulation in the fifth data group to obtain a first compensated external amplifier gain level, and compensating for the second link insertion loss based on the second data group after interpolation simulation in the fifth data group to obtain a second compensated external amplifier gain level;

[0182] S333: Based on the first compensated external amplifier gain level, the signal received by the antenna is transmitted to the first user identification card through the target port, and based on the second compensated external amplifier gain level, the signal received by the antenna is transmitted to the second user identification card through the target port.

[0183] In this embodiment, when two user identification cards of the electronic device work at the same time and have different working modes, the switch module is connected to multiple ports at the same time, which will cause link insertion loss on the link, causing loss of the signal transmitted from the antenna to the user identification card. The data under the corresponding conditions of the first port and the data under the corresponding conditions of the second port can be obtained in the fifth data group, that is, the first link insertion loss is compensated based on the first data group after interpolation simulation in the fifth data group to obtain the first compensated external amplifier gain level, and the second link insertion loss is compensated based on the second data group after interpolation simulation in the fifth data group to obtain the second compensated external amplifier gain level. Based on the first compensated external amplifier gain level, the signal received by the antenna is transmitted to the first user identification card through the target port, so that the antenna data corresponding to the first user identification card reduces the link insertion loss caused by multiple openings of the switch module. Based on the second compensated external amplifier gain level, the signal received by the antenna is transmitted to the second user identification card through the target port, so that the antenna data corresponding to the second user identification card reduces the link insertion loss caused by multiple openings of the switch module.

[0184] Based on the same concept, the present disclosure also provides a control device.
