[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] When users use smart terminals, dual-card dual-pass technology can ensure that the two SIM cards do not interfere with each other. For example, if a user is playing a game with the data of SIM card 1 and SIM card 2 is calling, the user can answer the call while continuing to play the game. For another example, users can even connect SIM card 1 and SIM card 2 to 5G calls at the same time without dropping the line.

[0035] In order to realize dual-SIM dual-pass, the relevant technology adopts the dual-SIM working mode of Full Concurrency DualSIM Dual Active (FC DSDA). In the dual-SIM working mode of Full Concurrency DualSIM Dual Active, the two SIM cards transmit signals in their respective frequency bands through independent power supplies and transmission paths.

[0036] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a radio frequency front-end architecture provided by an exemplary embodiment of the present application. Figure 1 As shown, the RF front-end architecture includes two independent power supplies, namely a first power supply 10 and a second power supply 11. In addition, the RF front-end architecture also includes a power amplifier and an antenna. The power amplifier is used to amplify the power of the signal of the corresponding working frequency band, and the antenna is used to receive the power-amplified signal and transmit it.

[0037] like Figure 1 The RF front-end architecture shown supports a first working mode, in which the dual cards transmit signals simultaneously in a first working frequency band and a second working frequency band.

[0038] Exemplarily, in the first working mode, the first power source 10 is used to supply power to the transmission path corresponding to the SIM card 1 .

[0039] When the signal transmitted by the SIM card 1 is a low frequency signal, the first power supply 10 supplies power to the LB PA low frequency power amplifier 111. The LB PA low frequency power amplifier 111 is used to amplify the power of the low frequency signal of the SIM card 1, and transmit the amplified low frequency signal to the antenna 0 (ANT0) or the antenna 1 (ANT1), and the antenna transmits the signal. The antenna 0 (ANT0) and the antenna 1 (ANT1) may be two antennas located at different positions on the terminal for transmitting low frequency signals.

[0040] Optionally, the LB PA low-frequency power amplifier 111 is a LB P7LE (Phase7L Enhancement) or other types of low-frequency power amplifiers.

[0041] When the signal transmitted by the SIM card 1 is a medium-high frequency band signal, the first power supply 10 supplies power to the MHB PA medium-high frequency power amplifier 112. The MHB PA medium-high frequency power amplifier 112 is used to amplify the medium-high frequency signal of the SIM card 1, and transmit the amplified medium-high frequency signal to the antenna 2 (ANT2) or the antenna 3 (ANT3), and the antenna transmits the signal. Among them, the antenna 2 (ANT2) and the antenna 3 (ANT3) can be two antennas located at different positions on the terminal for transmitting medium-high frequency signals.

[0042] Optionally, the MHB PA mid-high frequency power amplifier 112 is an MHB P7LE, or other types of mid-high frequency power amplifiers.

[0043] When the signal transmitted by the SIM card 1 is an ultra-high frequency band signal, the first power supply 10 supplies power to the UHB PA ultra-high frequency power amplifier 113. The UHB PA ultra-high frequency power amplifier 113 is used to amplify the power of the medium and high frequency signals of the SIM card 1, and transmit the power-amplified medium and high frequency signals to the antenna 8 (ANT8) or the antenna 9 (ANT9), and the antenna transmits the signal. Among them, the antenna 8 (ANT8) and the antenna 9 (ANT9) can be two antennas located at different positions on the terminal for transmitting ultra-high frequency signals.

[0044] Optionally, the UHB PA ultra-high frequency power amplifier 113 is an N77 LPAF power amplifier, or a power amplifier corresponding to other ultra-high frequency bands.

[0045] Exemplarily, in the first working mode, the second power supply 11 is used to supply power to the transmission path corresponding to the SIM card 2 .

[0046] When the signal transmitted by the SIM card 2 is a medium-high frequency band signal, the second power supply 11 supplies power to the MHB PA medium-high frequency power amplifier 121. The MHB PA medium-high frequency power amplifier 121 is used to amplify the medium-high frequency signal of the SIM card 2, and transmit the amplified medium-high frequency signal to the antenna 4 (ANT4) or the antenna 5 (ANT5), and the antenna transmits the signal.

[0047] Optionally, the MHB PA medium- and high-frequency power amplifier 121 is an MHB ENDC, or a medium- and high-frequency power amplifier with other working modes.

[0048] When the signal transmitted by the SIM card 2 is an ultra-high frequency band signal, the second power supply 11 supplies power to the UHB PA ultra-high frequency power amplifier 122. The UHB PA ultra-high frequency power amplifier 122 is used to amplify the ultra-high frequency signal of the SIM card 2, and transmit the ultra-high frequency signal after power amplification to the antenna 6 (ANT6) or the antenna 7 (ANT7), and the antenna transmits the signal.

[0049] Optionally, the UHB PA ultra-high frequency power amplifier 112 is an N77 LPAF power amplifier, or a power amplifier corresponding to other ultra-high frequency bands.

[0050] It should be noted that the above embodiment only describes the general architecture of the RF front-end architecture, and the RF front-end architecture may also include more or fewer components, or combine certain components, and this embodiment does not limit this. For example, the RF front-end architecture may also include an RF front-end module integrated with components such as an RF switch, a low-noise amplifier, and a filter, such as a LMHB LFEM low, medium, and high frequency RF front-end module and a MHB LFEM medium and high frequency RF front-end module.

[0051] During the signal transmission process, the antenna may be switched for certain working frequency bands. For example, when the signal transmitted by SIM card 2 is a medium-high frequency band signal, the second power supply 11 supplies power to the MHB PA medium-high frequency power amplifier 121, and the medium-high frequency signal after power amplification is transmitted through antenna 4 (ANT4). However, due to factors such as the user's holding posture (such as the user blocking the position of antenna 4 in the terminal), the working performance of antenna 4 (ANT4) may not be high. Therefore, it is necessary to switch the antenna to transmit the medium-high frequency band signal of SIM card 2.

[0052] In a possible scenario, the antenna corresponding to the medium and high frequency band signal of SIM card 2 is switched from antenna 4 (ANT4) to antenna 5 (ANT5), where antenna 4 and antenna 5 are at different positions of the terminal. Since antenna 5 is not blocked, it has higher signal transmission performance, so signal transmission can be better performed after switching the antenna. Switching from antenna 4 to antenna 5 only changes the connection between the MHBPA medium and high frequency power amplifier 121 and antenna 4 and antenna 5, and does not involve switching of power supply.

[0053] During the operation of dual cards, in another possible scenario, the antenna corresponding to the mid-high frequency band signal of SIM card 2 may also be switched from antenna 4 (ANT4) to antenna 2 (ANT2) or antenna 3 (ANT3). At this time, it is necessary to switch the power supply from the second power supply 11 to the first power supply 10, and power the MHB PA mid-high frequency power amplifier 112 through the first power supply 10, and the MHB PA mid-high frequency power amplifier 112 amplifies the mid-high frequency band signal of SIM card 2, and transmits the amplified mid-high frequency band signal through antenna 2 or antenna 3. Antenna 4 and antenna 2 or antenna 3 are at different positions of the terminal. Since antenna 2 or antenna 3 is not blocked and has higher signal transmission performance, signal transmission can be better performed after switching the antenna.

[0054] However, in the above example, when the antenna corresponding to the mid- and high-frequency band signals of SIM card 2 is switched from antenna 4 to antenna 2 or antenna 3, due to the power switching, the first power supply 10 simultaneously powers the MHB PA mid- and high-frequency power amplifier 112 and the power amplifier corresponding to another frequency band (such as the LB PA low-frequency power amplifier 111), resulting in a power conflict, making the dual-card working mode unable to work normally, affecting the dual-card experience.

[0055] Specifically, when the power source is switched from the second power source 11 to the first power source 10, and the first power source 10 is used to power the MHB PA medium- and high-frequency power amplifier 112, the first power source 10 is also simultaneously powering the transmission path corresponding to the signal of the SIM card 1. For example, the first power source 10 may simultaneously power the LB PA low-frequency power amplifier 111. At this time, since the first power source 10 is simultaneously powering two transmission paths, a power conflict will occur.

[0056] In order to solve the problem of power conflict caused by switching antennas in dual-card working mode, an embodiment of the present application provides a dual-card working method. When there is a need to switch antennas and there is a power conflict after the antennas are switched, the dual-card is controlled to switch from the first working mode to the second working mode, wherein in the second working mode, the power supply is time-sharingly supplied to the two transmission paths, thereby avoiding the problem of power conflict and improving the dual-card experience.

[0057] See also Figure 2, Figure 2 1 is a flow chart of a dual-SIM card working method provided by an exemplary embodiment of the present application. The method comprises the following steps:

[0058] Step 201, controlling the dual cards to transmit signals in a first working mode, wherein in the first working mode, the first SIM card in the dual cards supports a first working frequency band for signal transmission, the second SIM card in the dual cards supports a second working frequency band for signal transmission, and the first working frequency band and the second working frequency band transmit signals simultaneously.

[0059] In some embodiments, the first operating frequency band and the second operating frequency band may be the same or different operating frequency bands. In some embodiments, the first operating frequency band and the second operating frequency band may belong to the same or different operating frequency band ranges (such as low frequency band, medium-high frequency band and ultra-high frequency band), corresponding to power amplifiers of the same or different frequency band ranges.

[0060] For example, low frequency band signals may refer to signals in the range of 600 MHz to 940 MHz, mid- to high frequency band signals may refer to signals in the range of 1.4 GHz to 2.7 GHz, and ultra-high frequency band signals may refer to signals in the range of 3.3 GHz to 4.9 GHz. For example, ultra-high frequency band signals may include the N77 frequency band (3.3 GHz to 4.2 GHz).

[0061] It should be noted that the low frequency band, medium and high frequency band and ultra-high frequency band are relative divisions of the working frequency band. The working frequency band can also be divided according to other numerical values. For example, the low frequency band can also refer to the 450MHz-900MHz signal. The embodiment of the present application does not limit the specific division method of the working frequency band range.

[0062] Exemplarily, the first SIM card (or SIM card 1) supports n1 band signals for signal transmission, the second SIM card (or SIM card 2) supports n28 band signals for signal transmission, and n1 band and n28 band transmit signals simultaneously. The first working frequency band is n1 band (2.1GHz), which is a medium-high frequency band signal, corresponding to a medium-high frequency power amplifier; the second working frequency band is n28 band (700MHz), which is a low frequency band signal, corresponding to a low frequency power amplifier.

[0063] Exemplarily, the first SIM card (or SIM card 1) supports the signal of the B9 frequency band for signal transmission, the second SIM card (or SIM card 2) supports the signal of the B11 frequency band for signal transmission, and the B9 frequency band and the B11 frequency band transmit signals at the same time. Among them, the first working frequency band is the B9 frequency band (1749.9MHZ~1784.9MHZ), which belongs to the medium and high frequency band signal; the second working frequency band is the B11 frequency band (1427.9MHZ~1452.9MHZ), which also belongs to the medium and high frequency band signal. The B9 frequency band and the B11 frequency band can correspond to two different medium and high frequency power amplifiers in the first working mode.

[0064] Optionally, the first working mode is full concurrency dual SIM dual active (FC DSDA).

[0065] In the first working mode, the dual SIM cards transmit signals in the first working frequency band and the second working frequency band at the same time. For example, in the full concurrent dual SIM dual pass dual SIM working mode, the two SIM cards transmit signals in the first working frequency band and the second working frequency band respectively through independent power supplies and transmission paths.

[0066] Step 202, controlling the dual SIM cards to switch from a first working mode to a second working mode.

[0067] In some embodiments, step 202 may be triggered under certain conditions. For example, step 202 may be triggered when there is a need to switch the transmitting antenna and there is a power conflict after the antenna is switched.

[0068] Step 203, control the dual cards to transmit signals in the second working mode, wherein in the second working mode, the power supply is used for time-sharing power supply to two antenna transmission paths, the first SIM card supports signal transmission in the first working frequency band, the second SIM card supports signal transmission in the second working frequency band, and the first working frequency band and the second working frequency band perform time-sharing signal transmission.

[0069] Exemplarily, time-sharing power supply may refer to powering different antenna transmission paths in different time slots. For example, in the first time slot, the power supply powers the antenna transmission path corresponding to the first SIM card, in the second time slot, the power supply powers the antenna transmission path corresponding to the second SIM card, in the third time slot, the power supply powers the antenna transmission path corresponding to the first SIM card, in the fourth time slot, the power supply powers the antenna transmission path corresponding to the second SIM card, and so on and so forth.

[0070] Optionally, the second working mode is a time-sharing DSDA mode, such as Transmit-x sharing Dual Sim Dual Active (Tx-sharing DSDA) or Dual Receive Dual Sim Dual Active (DR-DSDA).

[0071] In one possible scenario, power conflicts may occur during dual-SIM usage. Power conflicts refer to the same power supply powering two antenna transmission paths at the same time. For example, when there is a need to switch the transmitting antenna, the same power supply may power two antenna transmission paths at the same time after the antenna is switched, resulting in a power conflict.

[0072] To sum up, by controlling the dual cards to switch from the first working mode to the second working mode, the dual cards can perform time-sharing signal transmission in the first working frequency band and the second working frequency band. When there is a need to switch the transmitting antenna and there is a power conflict after the antenna is switched, the power conflict caused by the same power supply supplying power to the two antenna transmitting paths at the same time can be avoided, thereby improving the user's dual-card dual-channel experience.

[0073] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of a dual-card working method provided by another exemplary embodiment of the present application. The method comprises the following steps:

[0074] Step 301, controlling the dual SIM cards to transmit signals in a first working mode, wherein in the first working mode, the dual SIM cards transmit signals in a first working frequency band and a second working frequency band simultaneously.

[0075] Optionally, SIM card 1 supports signals of a first working frequency band for signal transmission, and SIM card 2 supports signals of a second working frequency band for signal transmission. The first working frequency band and the second working frequency band may belong to the same or different working frequency band ranges, for example, the first working frequency band and the second working frequency band both belong to a low frequency band, or the first working frequency band belongs to a medium-high frequency band and the second working frequency band belongs to a low frequency band.

[0076] Optionally, the first working mode is full concurrency dual SIM dual active (FC DSDA).

[0077] For example, low frequency band signals may refer to signals in the range of 600 MHz to 940 MHz, mid- to high frequency band signals may refer to signals in the range of 1.4 GHz to 2.7 GHz, and ultra-high frequency band signals may refer to signals in the range of 3.3 GHz to 4.9 GHz. For example, ultra-high frequency band signals may include the N77 frequency band (3.3 GHz to 4.2 GHz).

[0078] It should be noted that the low frequency band, medium-high frequency band and ultra-high frequency band are relative divisions of the working frequency band. The working frequency band can also be divided according to other numerical values. For example, the low frequency band can also refer to the 450MHz-900MHz signal. The embodiment of the present application does not limit the specific division method of the working frequency band.

[0079] The first working frequency band may indicate the working frequency band to which the transmission signal of SIM card 1 belongs, and the second working frequency band may indicate the working frequency band to which the transmission signal of SIM card 2 belongs. The first working frequency band and the second working frequency band may belong to the same or different working frequency bands, for example, the first working frequency band is the n1 frequency band (2.1 GHz), which belongs to the medium-high frequency band signal, and the second working frequency band is the n28 frequency band (700 MHz), which belongs to the low frequency band signal; or the first working frequency band and the second working frequency band are both the n1 frequency band, which belong to the medium-high frequency band signal.

[0080] Step 302, when there is a need to switch the transmitting antenna and there is a power conflict after the antenna switching, control the dual card to switch from the first working mode to the second working mode, wherein the power conflict means that the same power supply supplies power to two antenna transmitting paths at the same time.

[0081] In one possible scenario, due to factors such as the user's holding posture, the antenna's working performance is not high, so there is a need to switch the transmitting antenna, and it is necessary to switch the antenna that is transmitting the signal to another antenna.

[0082] In some embodiments, the transmitting antenna switching requirement may be triggered based on an application processor (AP). For example, when the application processor obtains a change in the degree of antenna shielding, or when the application processor obtains a change in the holding posture, the transmitting antenna switching requirement needs to be triggered.

[0083] Power conflict means that the same power supply is used to power two antenna transmission paths at the same time. Figure 1 In the embodiment, if the first power supply 10 supplies power to the MHB PA medium-high frequency power amplifier 112 and the LB PA low frequency power amplifier 111 at the same time, power supply conflict will occur.

[0084] Regarding the first working mode, the following will be combined with Figure 4 and Figure 5 The first operation mode will be described.

[0085] In the first working mode, the dual SIM cards transmit signals in the first working frequency band and the second working frequency band at the same time. For example, in the full concurrent dual SIM dual pass dual SIM working mode, the two SIM cards transmit signals in the first working frequency band and the second working frequency band respectively through independent power supplies and transmission paths.

[0086] See also Figure 4 , Figure 4 It is a schematic diagram of a radio frequency front end in a first working mode provided by an exemplary embodiment of the present application.

[0087] like Figure 4 As shown, the first working frequency band is a medium-high frequency band, and the first power supply 40 supplies power to the MHB PA medium-high frequency power amplifier 411. The MHB PA medium-high frequency power amplifier 411 amplifies the medium-high frequency signal of the SIM card 1, and transmits the amplified medium-high frequency signal to the antenna 2 (ANT2), and the antenna 2 transmits the signal.

[0088] The second working frequency band is the UHF band, and the second power supply 41 supplies power to the UHBPA UHF power amplifier 421. The UHBPA UHF power amplifier 421 amplifies the UHF signal of the SIM card 2, and transmits the amplified UHF signal to the antenna 7 (ANT7), which transmits the signal.

[0089] It should be noted that Figure 4 The first working mode is described by taking the working frequency band combination in which the first working frequency band is a medium-high frequency band and the second working frequency band is an ultra-high frequency band as an example. In some embodiments, in the first working mode, there may be other working frequency band combinations. For example, in the first working mode, the first working frequency band may be a low frequency band, and the second working frequency band may be a medium-high frequency band, which is not limited in the embodiments of the present application.

[0090] See also Figure 5 , Figure 5 It is a schematic diagram of the power supply situation in the first working mode provided by an exemplary embodiment of the present application.

[0091] like Figure 5 As shown, in the first working mode, the first power supply 40 and the second power supply 41 work simultaneously, and each supplies power to two antenna transmission paths corresponding to the first working frequency band and the second working frequency band in the time interval [T0, T1]. Specifically, in the time interval [T0, T1], the first power supply 40 continuously supplies power to the MHB PA medium and high frequency power amplifier 411, and the second power supply 41 continuously supplies power to the UHB PA ultra-high frequency power amplifier 421, so that the dual card transmits signals simultaneously in the first working frequency band and the second working frequency band.

[0092] Since in the first working mode, the first working frequency band and the second working frequency band transmit signals simultaneously, the first working mode can have a higher uplink throughput.

[0093] Regarding the second working mode, the following will be combined with Figure 6 and Figure 7 The second operation mode will be described.

[0094] In the second working mode, the same power supply supplies power to the two antenna transmission paths in a time-sharing manner, and the dual cards transmit signals in a time-sharing manner in the first working frequency band and the second working frequency band.

[0095] Exemplarily, time-sharing power supply may refer to powering different antenna transmission paths in different time slots. For example, in the first time slot, the power supply powers the first antenna transmission path, in the second time slot, the power supply powers the second antenna transmission path, in the third time slot, the power supply powers the first antenna transmission path, in the fourth time slot, the power supply powers the second antenna transmission path, and so on and so forth.

[0096] Optionally, the second working mode is a time-sharing DSDA mode, such as Transmit-x sharing Dual Sim Dual Active (Tx-sharing DSDA) or Dual Receive Dual Sim Dual Active (DR-DSDA).

[0097] See also Figure 6 , Figure 6 It is a schematic diagram of a radio frequency front end in a second working mode provided by an exemplary embodiment of the present application.

[0098] like Figure 6 As shown, the first working frequency band is a medium-high frequency band, and the first power supply 60 supplies power to the MHB PA medium-high frequency power amplifier 611. The MHB PA medium-high frequency power amplifier 611 amplifies the medium-high frequency signal of the SIM card 1, and transmits the amplified medium-high frequency signal to the antenna 2 (ANT2), and the antenna 2 transmits the signal.

[0099] The second working frequency band is the UHF band, and the first power source 60 supplies power to the UHBPA UHF power amplifier 621. The UHBPA UHF power amplifier 621 amplifies the UHF signal of the SIM card 2, and transmits the amplified UHF signal to the antenna 8 (ANT8), which transmits the signal.

[0100] It should be noted that Figure 6The second working mode is described by taking the working frequency band combination in which the first working frequency band is a medium-high frequency band and the second working frequency band is an ultra-high frequency band as an example. In some embodiments, in the second working mode, there may be other working frequency band combinations. For example, in the second working mode, the first working frequency band may be a low frequency band, and the second working frequency band may be a medium-high frequency band, which is not limited in the embodiments of the present application.

[0101] See also Figure 7 , Figure 7 It is a schematic diagram of the power supply situation in the second working mode provided by an exemplary embodiment of the present application.

[0102] like Figure 7 As shown, in the second working mode, only the first power supply 60 works, and the first power supply 60 simultaneously supplies power to two antenna transmission paths corresponding to the first working frequency band and the second working frequency band in a time-sharing manner.

[0103] Specifically, in the time interval [T0, t1], the first power supply 60 supplies power to the MHB PA medium and high frequency power amplifier 611 corresponding to the first working frequency band; in the time interval [t1, t2], the first power supply 60 supplies power to the UHB PA ultra-high frequency power amplifier 621 corresponding to the second working frequency band; in the time interval [t2, t3], the first power supply 60 supplies power to the MHBPA medium and high frequency power amplifier 611 corresponding to the first working frequency band; in the time interval [t3, t4], the first power supply 60 supplies power to the UHB PA ultra-high frequency power amplifier 621 corresponding to the second working frequency band; in the time interval [t4, T1], the first power supply 60 supplies power to the MHB PA medium and high frequency power amplifier 611 corresponding to the first working frequency band… This is performed alternately, so that the dual cards perform time-sharing signal transmission in the first working frequency band and the second working frequency band.

[0104] Since in the second working mode, the second working frequency band and the second working frequency band use a time-sharing method to transmit signals, the uplink throughput in the second working mode is generally higher, but not as high as the uplink throughput in the first working mode.

[0105] Step 303, when the antenna switching is completed, control the dual cards to transmit signals in the second working mode, wherein in the second working mode, the power supply is time-sharing power for the two transmission paths, and the dual cards transmit signals in the first working frequency band and the second working frequency band in time-sharing.

[0106] like Figure 1As shown, in the process of switching the antenna corresponding to the medium and high frequency band signal of SIM card 2 from antenna 5 to antenna 2 or antenna 3, the power supply is switched from the second power supply 11 to the first power supply 10, so that the first power supply 10 simultaneously supplies power to the MHB PA medium and high frequency power amplifier 112 and the LB PA low frequency power amplifier 111. At this time, when the antenna switching is completed, the dual cards can be controlled to transmit signals in the second working mode, so that the first power supply adopts a time-sharing manner to supply power to the MHB PA medium and high frequency power amplifier 112 and the LB PA low frequency power amplifier 111, thereby avoiding power supply conflicts.

[0107] To sum up, when there is a need to switch the transmitting antenna and there is a power conflict after the antenna is switched, by controlling the dual cards to switch from the first working mode to the second working mode, the dual cards can perform time-sharing signal transmission in the first working frequency band and the second working frequency band, thereby avoiding the power conflict caused by the same power supply supplying power to two antenna transmission paths at the same time, and improving the user's dual-card dual-channel experience.

[0108] When there is a need to switch the transmitting antenna, in order to determine whether the antenna switching will cause a power conflict, a judgment can be made based on the working state of the transmitting antenna and the power state.

[0109] In some embodiments, after the antenna is switched, the first transmitting antenna corresponding to the first working frequency band and the second transmitting antenna corresponding to the second working frequency band can be determined; when the two antenna transmission paths corresponding to the first transmitting antenna and the second transmitting antenna correspond to the same power supply, it is determined that there is a power supply conflict.

[0110] See also Figure 8 , Figure 8 It is a schematic diagram of a power supply conflict caused by antenna switching provided by an exemplary embodiment of the present application.

[0111] like Figure 8 (a) and Figure 8 As shown in (b), the transmitting antenna switching requirement is to switch antenna 4 (ANT4) to antenna 3 (ANT3).

[0112] like Figure 8 As shown in (a), before the antenna is switched, the first power supply 80 supplies power to the LB PA low-frequency power amplifier 811. The LBPA low-frequency power amplifier 811 amplifies the low-frequency signal of SIM card 1, and transmits the amplified low-frequency signal to antenna 1 (ANT1), and antenna 1 transmits the signal. The second power supply 81 supplies power to the MHB PA medium-high frequency power amplifier 821. The MHB PA medium-high frequency power amplifier 821 amplifies the medium-high frequency signal of SIM card 2, and transmits the amplified medium-high frequency signal to antenna 4 (ANT4), and antenna 4 transmits the signal.

[0113] After the antenna is switched, antenna 4 (ANT4) is switched to antenna 3 (ANT3), and the first power supply 80 simultaneously supplies power to the LB PA low-frequency power amplifier 711 and the MHB PA medium-high frequency power amplifier 822. The MHB PA medium-high frequency power amplifier 822 amplifies the medium-high frequency signal of the SIM card 2, and transmits the amplified medium-high frequency signal to antenna 3 (ANT3), which transmits the signal, thereby realizing the switching from antenna 4 to antenna 3.

[0114] like Figure 8 As shown in (b), after the antenna is switched, the first transmitting antenna corresponding to the first working frequency band is antenna 1 (ANT1), and the second transmitting antenna corresponding to the second working frequency band is antenna 3 (ANT3), and the two antenna transmitting paths corresponding to antenna 1 and antenna 3 correspond to the same power supply (both are the first power supply 80). Therefore, it can be determined that after antenna 4 is switched to antenna 3, there is a power supply conflict.

[0115] In some embodiments, when the power conflict situation indicates that there is a power conflict, the dual SIM cards are controlled to switch from the first working mode to the second working mode. For example, the first power supply 80 uses a time-division method to alternately power the antenna transmission paths corresponding to the first working frequency band and the second working frequency band, thereby avoiding power conflicts caused by the same power supply powering the two antenna transmission paths at the same time, thereby improving the user's dual-SIM dual-channel experience.

[0116] See also Fig. 9 , Fig. 9 It is a schematic diagram showing that antenna switching does not cause power supply conflict, provided by an exemplary embodiment of the present application.

[0117] like Fig. 9 (a) and Fig. 9 As shown in (b), the transmitting antenna switching requirement is to switch antenna 2 (ANT2) to antenna 5 (ANT5), and at the same time switch antenna 7 (ANT7) to antenna 9 (ANT9).

[0118] like Fig. 9 As shown in (a), before the antenna is switched, the first power supply 90 supplies power to the MHB PA medium and high frequency power amplifier 911. The MHB PA medium and high frequency power amplifier 911 is used to amplify the medium and high frequency signals of the SIM card 1, and transmit the power-amplified medium and high frequency signals to the antenna 2 (ANT2), and the antenna 2 transmits the signal. The second power supply 91 supplies power to the UHB PA ultra-high frequency power amplifier 921. The UHB PA ultra-high frequency power amplifier 921 is used to amplify the power of the ultra-high frequency signal of the SIM card 2, and transmit the power-amplified ultra-high frequency signal to the antenna 7 (ANT7), and the antenna 7 transmits the signal.

[0119] like Fig. 9 As shown in (b), after the antenna is switched, antenna 2 (ANT2) is switched to antenna 5 (ANT5), and antenna 7 (ANT7) is switched to antenna 9 (ANT9), and the first power supply 90 supplies power to the UHB PA ultra-high frequency power amplifier 922. The UHB PA ultra-high frequency power amplifier 922 amplifies the medium and high frequency signals of the SIM card 1, and transmits the amplified medium and high frequency signals to antenna 9 (ANT9), which transmits the signals, thereby realizing the switching from antenna 7 to antenna 9.

[0120] The second power supply 91 supplies power to the MHB PA medium and high frequency power amplifier 912. The MHB PA medium and high frequency power amplifier 912 amplifies the medium and high frequency signals of the SIM card 2, and transmits the amplified medium and high frequency signals to the antenna 5 (ANT5), which transmits the signals, thereby realizing the switching from the antenna 2 to the antenna 5.

[0121] Depend on Fig. 9 It can be seen that after the antenna is switched, the first transmitting antenna corresponding to the first working frequency band is antenna 9 (ANT9), and the second transmitting antenna corresponding to the second working frequency band is antenna 5 (ANT5). The two antenna transmission paths corresponding to antenna 5 and antenna 9 correspond to different power supplies (antenna 9 corresponds to the first power supply 90, and antenna 5 corresponds to the second power supply 91). Therefore, it can be judged that after switching antenna 7 to antenna 9 and antenna 2 to antenna 5, there is no power supply conflict.

[0122] In some embodiments, when the power conflict situation indicates that there is no power conflict, the dual cards are controlled to maintain the first working mode. Fig. 9 After the antenna switching shown, the dual SIM cards will continue to maintain the dual SIM card dual-pass working mode with full concurrency.

[0123] In this embodiment, when the power conflict situation indicates that there is no power conflict, the dual cards are controlled to maintain the first working mode. Since the dual cards can have a higher uplink throughput in the first working mode, there will be no power conflict and more uplink data transmission can be performed.

[0124] Avoiding power conflicts by switching working modes requires some prerequisites. For example, the current frequency band combination consisting of the first working frequency band and the second working frequency band should support the first working mode; for another example, the first working frequency band and / or the second working frequency band should support antenna switching; for another example, when there is a need to switch the transmitting antenna, the power conflict situation indicates the existence of a power conflict.

[0125] In order to realize reasonable switching of the dual-card working mode, it is necessary to judge the above-mentioned preconditions in sequence, and switch to the appropriate dual-card working mode based on the judgment result.

[0126] See also Fig.10 , Fig.10 It is a flowchart of switching dual-SIM card working modes provided by an exemplary embodiment of the present application.

[0127] In some embodiments, the steps included in the flowchart may be performed by a baseband chip. The baseband chip may also be referred to as a modem. The flowchart includes the following steps.

[0128] Step 1010: determine the working mode supported by the current frequency band combination, where the current frequency band combination consists of a first working frequency band and a second working frequency band for dual-SIM operation.

[0129] Exemplarily, when the first working frequency band is the n1 band (2.1GHz) and the second working frequency band is the n28 band (700MHz), the current frequency band combination is "medium-high frequency band + low frequency band"; when the first working frequency band is the n78 band (3.4GHz-3.5GHz) and the second working frequency band is the n28 band (700MHz), the current frequency band combination is "ultra-high frequency band + low frequency band".

[0130] Since not all frequency band combinations support the first working mode of simultaneous signal transmission, it is necessary to first perform step 1010 to determine the working mode supported by the current frequency band combination. In some embodiments, the working mode supported by the current frequency band combination can be determined from the dual-card configuration table based on the current frequency band combination.

[0131] Step 1011, determine whether the working modes supported by the current frequency band combination include the first working mode?

[0132] When the working modes supported by the current frequency band combination do not include the first working mode, since there is no power conflict involved, step 1043 is directly executed to control the dual cards to maintain the current working mode.

[0133] When the working modes supported by the current frequency band combination include the first working mode, step 1020 is executed.

[0134] Step 1020: Determine the transmit antenna switching support status of the current frequency band combination. The transmit antenna switching support status is used to indicate whether the working frequency band in the current frequency band combination supports antenna switching.

[0135] Since not all frequency band combinations support transmit antenna switching (for example, the transmit front-end architecture may not have multiple antennas corresponding to the working frequency band), it is necessary to perform step 1020 to determine the antenna switching support corresponding to the current frequency band combination. In some embodiments, the antenna switching support includes the antenna switching support corresponding to the first working frequency band and / or the second working frequency band.

[0136] Step 1021, determine whether the working frequency band in the current frequency band combination supports antenna switching?

[0137] When the working frequency band in the current frequency band combination does not support antenna switching, since there is no power conflict involved, step 1043 is directly executed to control the dual SIM cards to maintain the current working mode.

[0138] If the working frequency band in the current frequency band combination supports antenna switching, step 1030 is performed.

[0139] Step 1030: When there is a need to switch the transmitting antenna, determine the power conflict situation based on the operating state and power state of the transmitting antenna.

[0140] Optionally, when there is a need to switch the transmitting antenna, the first transmitting antenna corresponding to the first working frequency band and the second transmitting antenna corresponding to the second working frequency band are determined after the antenna switching; when the two antenna transmission paths corresponding to the first transmitting antenna and the second transmitting antenna correspond to the same power supply, the power supply conflict situation is determined to be a power supply conflict.

[0141] Step 1031, determine whether the power conflict situation indicates that there is a power conflict?

[0142] When the power conflict situation indicates that there is no power conflict, there is no need to switch the working mode, so step 1042 is executed to control the dual cards to maintain the first working mode.

[0143] When the power conflict situation indicates that there is a power conflict, in order to avoid the power conflict, the dual-card working mode needs to be switched to the second working mode, so step 1041 is executed.

[0144] Step 1041, controlling the dual SIM cards to switch from the first working mode to the second working mode.

[0145] Among them, in the second working mode, the power supply is used for the two antenna transmission paths in a time-sharing manner, and the dual cards perform time-sharing signal transmission in the first working frequency band and the second working frequency band.

[0146] In this embodiment, by judging the precondition, it is possible to switch the first working mode to the second working mode in the case of a power conflict caused by antenna switching, so as to perform time-sharing signal transmission on the first working frequency band and the second working frequency band. In other cases where no power conflict occurs, the current working mode is maintained.

[0147] When transmitting signals in the second working mode, the power supply uses a time-sharing method to supply power to the two transmission paths corresponding to the dual SIM cards. In some cases, the dual SIM cards have different uplink throughput requirements, and the power supply duration required for the dual SIM cards may also be different. For example, for a SIM card with a higher uplink throughput requirement, the power supply duration required is relatively longer.

[0148] In some embodiments, time slots may be allocated to the dual cards based on the uplink throughput requirements corresponding to the dual cards, wherein the time slot length is positively correlated with the uplink throughput requirement.

[0149] See also Fig.11 , Fig.11 It is a schematic diagram of allocating time slots according to uplink throughput requirements provided by an exemplary embodiment of the present application.

[0150] like Fig.11 As shown in (a), the uplink throughput requirement of SIM card 1 is 200 kbps, and the uplink throughput requirement of SIM card 2 is 500 kbps, that is, the uplink throughput ratio of the two cards is 2:5.

[0151] In a possible implementation, the application processor may obtain the service type (such as uploading a video, making a call, or browsing a page) being performed by the dual cards, and determine the uplink throughput requirement of the dual cards based on the service type.

[0152] In some implementations, based on the time slot lengths corresponding to the dual cards respectively, the dual cards are controlled to transmit signals in the second working mode.

[0153] like Fig.11 As shown in (b), the power supply is powered in a time-sharing manner for the antenna transmission path corresponding to SIM card 1 and the antenna transmission path corresponding to SIM card 2 according to different time slot lengths based on the ratio of the uplink throughputs of the dual cards, wherein the ratio of the time slot lengths of the dual cards is also 2:5, for example, the time slot length corresponding to SIM card 1 is 20ms, and the time slot length corresponding to SIM card 2 is 50ms.

[0154] Specifically, within 0-20ms, the power supply supplies power to the antenna transmission path of SIM card 1; within 20-70ms, the power supply supplies power to the antenna transmission path of SIM card 2; within 70-90ms, the power supply supplies power to the antenna transmission path of SIM card 1... and so on alternately.

[0155] In this embodiment, time slots are allocated according to the uplink throughput requirements of the dual cards, and signals are transmitted in the second working mode according to the time slot lengths corresponding to each of the dual cards. This can ensure that for a SIM card with a higher uplink throughput, the power supply lasts for a relatively longer time, thereby achieving reasonable utilization of power supply resources.

[0156] Due to factors such as user occlusion, the antenna performance is reduced, so it may be necessary to switch the antenna to improve the signal transmission quality. In one possible case, when the uplink throughput requirement of the dual-card is high, the sensitivity requirement for switching the transmitting antenna is also high. For example, the transmitting antenna needs to be switched as soon as possible, or when the antenna performance is slightly reduced, it needs to be switched. When the uplink throughput requirement of the dual-card is low, the sensitivity requirement for antenna switching is relatively low. Therefore, the conditions for switching the transmitting antenna can be adjusted based on the uplink throughput requirement of the dual-card.

[0157] In a possible implementation, the transmitting antenna switching requirement may be triggered by an application processor. The application processor may obtain data such as the degree of shielding of the transmitting antenna by the user or the user's holding posture. When the shielding degree is greater than a preset value or the holding posture meets a preset condition, the transmitting antenna switching requirement is triggered.

[0158] When the transmitting antenna switching requirement is triggered by the application processor, a trigger condition adjustment instruction can be sent to the application processor based on the uplink throughput requirement of the dual cards, wherein the trigger condition adjustment instruction is used to instruct the application processor to adjust the condition for triggering the switching of the transmitting antenna.

[0159] See also Fig.12 , Fig.12 It is a schematic diagram of information interaction between a baseband chip and an application processor provided by an exemplary embodiment of the present application.

[0160] like Fig.12 As shown, regarding the method of sending a trigger condition adjustment instruction to an application processor based on the uplink throughput requirement of a dual card, there may be at least one of the following ways.

[0161] (1) When the uplink throughput demand of the dual-SIM cards is greater than the demand threshold, the baseband chip 1201 sends a first trigger condition adjustment instruction to the application processor 1202.

[0162] The first trigger condition adjustment instruction is used to instruct the application processor 1202 to lower the threshold for triggering the switching of the transmitting antenna, so that the sensitivity of the switching of the transmitting antenna is improved.

[0163] Exemplarily, the threshold for triggering the switching of the transmitting antenna may be the blocking area threshold of the transmitting antenna. For example, the original blocking area threshold of the transmitting antenna is 30%. When the application processor 1202 obtains that the actual blocking area of ​​the transmitting antenna is greater than 30%, the transmitting antenna switching requirement is triggered, and the application processor 1202 transmits the transmitting antenna switching requirement to the baseband chip 1201. After receiving the first trigger condition adjustment instruction, the application processor 1202 lowers the blocking area threshold of the transmitting antenna to 10%. When the actual blocking area of ​​the transmitting antenna is greater than 10%, the transmitting antenna switching requirement is triggered, thereby increasing the sensitivity of the transmitting antenna switching.

[0164] Exemplarily, the threshold for triggering the switching of the transmitting antenna may also be the threshold of the degree of change in the holding posture. For example, the original threshold of the degree of change in the holding posture is 55%. When the application processor 1202 obtains that the actual degree of change in the user's holding posture exceeds 55%, the need to switch the transmitting antenna is triggered. After receiving the first trigger condition adjustment instruction, the application processor 1202 lowers the threshold of the degree of change in the holding posture to 35%. When the actual degree of change in the user's holding posture exceeds 35%, the need to switch the transmitting antenna is triggered, thereby increasing the sensitivity of the switching of the transmitting antenna.

[0165] It should be noted that the threshold for triggering the switching of the transmitting antenna can also be represented in other forms, such as representing the working performance of the antenna, etc., and the embodiments of the present application are not limited to this.

[0166] (2) When the uplink throughput requirement of the dual-SIM cards is less than the requirement threshold, the baseband chip 1201 sends a second trigger condition adjustment instruction to the application processor 1202 .

[0167] The second trigger condition adjustment instruction is used to instruct the application processor 1202 to increase the threshold for triggering the switching of the transmitting antenna, so that the sensitivity of the switching of the transmitting antenna is reduced.

[0168] Exemplarily, the threshold for triggering the switching of the transmitting antenna may be the blocking area threshold of the transmitting antenna. For example, the original blocking area threshold of the transmitting antenna is 30%. When the application processor 1202 obtains that the actual blocking area of ​​the transmitting antenna is greater than 30%, the transmitting antenna switching requirement is triggered, and the application processor 1202 transmits the transmitting antenna switching requirement to the baseband chip 1201. After receiving the second trigger condition adjustment instruction, the application processor 1202 increases the blocking area threshold of the transmitting antenna to 60%. When the actual blocking area of ​​the transmitting antenna is greater than 60%, the transmitting antenna switching requirement is triggered, thereby reducing the sensitivity of the transmitting antenna switching.

[0169] In an embodiment of the present application, the conditions for triggering the switching of the transmitting antenna are changed based on the uplink throughput requirements of the dual cards. This can improve the sensitivity of the transmitting antenna switching when the uplink throughput requirement is high, so that the transmitting antenna can be switched as soon as possible to improve the quality of signal transmission; when the uplink throughput requirement is low, the sensitivity of the transmitting antenna switching can be reduced to avoid unnecessary antenna switching requirements, thereby improving the efficiency of the dual-card operation.

[0170] After the antenna is switched, due to factors such as the user's holding posture changing again, the antenna may need to be switched again, for example, switching to the original transmitting antenna or switching to another transmitting antenna. In the scenario of switching the antenna again, the power conflict problem may not occur, so the dual-card working mode can be switched from the second working mode to the first working mode.

[0171] In some embodiments, after controlling the dual cards to transmit signals in the second working mode, if there is a need to switch the transmitting antenna and there is no power conflict after the antenna switching, the dual cards are controlled to switch from the second working mode to the first working mode, and the dual cards are controlled to transmit signals in the first working mode.

[0172] like Figure 7 As shown, switching antenna 4 to antenna 3 will cause power conflict, so the dual cards are controlled to switch from the first working mode to the second working mode, and the signals of the dual cards are transmitted in a time-sharing manner. If antenna 3 is switched back to antenna 4 afterwards, there will be no power conflict, so the dual cards can be controlled to switch from the second working mode back to the first working mode.

[0173] In this embodiment, when there is a need to switch the transmitting antenna and there is no power conflict after the antenna is switched, the dual cards are controlled to switch from the second working mode to the first working mode. Since the dual cards can have a higher uplink throughput in the first working mode, it will not cause power conflicts and can also perform more uplink data transmission.

[0174] In the first working mode, the dual cards transmit signals simultaneously in the first working frequency band and the second working frequency band.

[0175] In some embodiments, the first working mode is a full concurrent dual SIM dual access (FC DSDA) mode. In the full concurrent dual SIM dual access dual SIM working mode, the two SIM cards transmit signals in their respective frequency bands through independent power supplies and transmission paths. Figure 3 As shown, SIM card 1 is powered by a first power supply 30 to transmit low frequency band, medium and high frequency band and ultra high frequency band signals; SIM card 2 is powered by a second power supply 31 to transmit low frequency band, medium and high frequency band and ultra high frequency band signals.

[0176] In some embodiments, the second working mode is a time-sharing DSDA mode, such as a dual-card dual-channel Tx-sharing DSDA mode, or a dual-card dual-channel DR-DSDA mode. In the dual-card working mode of time-sharing DSDA, the same power supply is used to power the two antenna transmission paths in a time-sharing manner, and the dual cards transmit signals in a time-sharing manner in the first working frequency band and the second working frequency band. Figure 6 As shown, the two antenna transmission paths corresponding to SIM card 1 and SIM card 2 are both powered by the first power supply 60 in a time-sharing manner.
