The middle frame 103 is used for providing a supporting function for the electronic elements or functional components in the electronic device 100, so as to mount the electronic elements or functional components in the electronic device 100 together.

The middle frame 103 and the rear cover 106 may together form a housing of the electronic device 100, for accommodating or mounting electronic elements, functional components, and the like of the electronic device 100. For example, the display screen 101 may be mounted on the housing.

It is understood that the material of the middle frame 103 may include metal or plastic or composite material.

The circuit board 104 is mounted inside a housing formed by the middle frame 103 and the rear cover 106 together. For example, the circuit board 104 may be mounted on the middle frame 103. The circuit board 104 may be a motherboard of the electronic device 100. Wherein, the circuit board 104 is provided with a radio frequency circuit. The radio frequency circuitry is used to enable wireless communication between the electronic device 100 and a base station or other electronic device. The radio frequency circuit will be described in detail below.

The rear cover 106 may be integrally formed. In the molding process of the rear cover 106, a rear camera hole or the like may be formed in the rear cover 106.

The first subscriber identification card 107 may be mounted on the bezel 103 or on the circuit board 104 inside the electronic device. The first subscriber identification card 107 may serve as an information storage for storing identification information of the subscriber, such as a telephone number for indicating the identity of the subscriber. In addition, the first subscriber identification card 107 may also be used to store personal information of the subscriber, such as a key for encrypting voice contents at the time of a voice call, a phone book of the subscriber, and the like. The subscriber identity module card is also called a sim (subscriber identity module) card, a smart card, or the like.

It should be noted that, after the first user identification card 107 is installed on the electronic device 100, the electronic device 100 can communicate with a base station or other electronic devices through the information stored on the first user identification card 107.

A second user identification card 108 is also mounted on the center frame 103 or on the circuit board 104 inside the electronic device. The second user identification card may also serve as an information storage for storing identification information of the user, personal information of the user, and the like.

Wherein the user identification information stored on the second user identification card 108 is different from the user identification information stored on the first user identification card 107. For example, a first user identification card 107 stores first identification information of a user, such as a first telephone number for indicating the identity of the user, and a second user identification card 108 stores second identification information of the user, such as a second telephone number for indicating the identity of the user. In addition, the personal information of the user stored on the second user identification card 108 may be the same as or partially the same as or different from the personal information of the user stored on the first user identification card 107.

It should be noted that, after the second user identification card 108 is installed on the electronic device 100, the electronic device 100 can communicate with a base station or other electronic devices through the information stored on the second user identification card 108.

In the embodiment of the present application, the circuit board 104 is provided with a radio frequency circuit 200. The radio frequency circuit 200 is used to enable wireless communication between the electronic device 100 and a base station or other electronic devices.

The embodiment of the application can realize double-card double-pass of the electronic equipment based on the 5G communication technology. Among them, the 5G New Radio (NR) network includes an sa (Stand Alone) mode and an NSA (Non-Stand Alone) mode. In the SA mode, a 5G New Radio (NR) network is independently networked, which means that a New 5G network is created, including a New base station, a backhaul link, and a core network. In the NSA mode, a 5G New Radio (NR) network is non-independent networking, which means that an existing 4G infrastructure is used to deploy a 5G network.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a non-independent networking mode according to an embodiment of the present application. In the NSA mode, a 5G NR network and a 4G LTE network are combined to form a network, and the network is accessed in a dual-connection mode. By dual connectivity, it is meant that the electronic device remains connected to both the 5G base station and the 4G base station, i.e. the electronic device can transmit data to the 5G core network via both the 5G base station and the 4G base station. It should be noted that fig. 2 is only an example, and other network structures in a non-independent networking mode may also be applicable to the electronic device according to the embodiment of the present application.

In the control plane, based on the electronic device in the NSA mode, the control plane command is transmitted to the 5G core network only through the 4G base station, and the 5G base station only carries user plane data. This means that in NSA mode, if the electronic device is to communicate using a 5G NR network, it must be connected to both the 4G base station and the 5G base station, i.e. the electronic device must simultaneously modem the 4G radio frequency signal and the 5G radio frequency signal.

The electronic equipment of the embodiment of the application can realize double-card double-pass in the NSA mode. It should be noted that the electronic device according to the embodiment of the present application is not limited to the application in the NAS mode, and may be used in the SA mode or other 5G networking modes.

Referring to fig. 4, fig. 4 is a schematic diagram of a first structure of a radio frequency circuit according to an embodiment of the present disclosure. The radio frequency circuit includes a first antenna group 220, a second antenna group 240, and a processing module 260.

The first antenna group 220 includes at least six antennas (e.g., ANT0-ANT 5); second antenna group 240 includes at least two antennas (e.g., ANT6-ANT 7). The first antenna set 220 and the second antenna set 240 are both electrically connected to the processing module 260, and the processing module 260 is configured to transmit the 5G radio frequency signal and the 4G radio frequency signal of the first subscriber identity card 107 through the first antenna set 220, and transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna set 240.

The first antenna set 220 may include a first antenna sub-set 222 and a second antenna sub-set 224, the first antenna sub-set 222 may include at least four antennas, and the processing module 260 is configured to transmit a 5G radio frequency signal of the first subscriber identity card 107 through the first antenna sub-set 222; the second antenna group 224 may include at least two antennas, and the processing module 260 is configured to transmit the 4G radio frequency signal of the first subscriber identity card 107 through the second antenna group 224.

The processing module 260 transmits the 5G rf signal and the 4G rf signal of the first subscriber identity card 107 through the first antenna set 220, and transmits the 4G rf signal of the second subscriber identity card 108 through the second antenna set 240. The radio frequency circuit can not only realize 5G communication of the first user identification card 107, but also realize 4G communication of the second user identification card 108, and double-card double-pass based on the 5G communication technology is realized.

The processing module 260 may be configured to transmit the 5G radio frequency signal and the 4G radio frequency signal of the first subscriber identity card 107 through the first antenna set 220 and transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna set 240 in one transmission period.

Referring to fig. 5, fig. 5 is a first timing diagram of a radio frequency circuit according to an embodiment of the present disclosure. Specifically, the transmission cycle includes a first time period and a second time period which are continuous. In a first time period, the processing module 260 is configured to transmit a 5G radio frequency signal of the first subscriber identity card 107 through the first sub-antenna group 222 of the first antenna group 220 and transmit a 4G radio frequency signal of the first subscriber identity card 107 through the second sub-antenna group 224 of the first antenna group 220; in the second time period, the processing module 260 is configured to transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna set 240.

The transmission cycle may further include a third time period and a fourth time period, and it is also understood that the transmission cycle includes the first time period, the second time period, the third time period and the fourth time period in succession.

On the basis of the previous first time period and the second time period, in the third time period, the processing module 260 is further configured to transmit the 5G radio frequency signal and the 4G radio frequency signal of the first subscriber identity card 107 through the first antenna group 220; during the fourth time period, the processing module 260 is further configured to transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna set 240.

It should be noted that, in the embodiment of the present application, the first subscriber identity module 107 is in a standby state, and the second subscriber identity module 108 is also in a standby state, at this time, a dual-card dual standby based on a 5G communication technology may be implemented by multiplexing the first antenna set 220 and the second antenna set 240 in a time-sharing manner (the first subscriber identity module 107 is in a 5G standby state, and the second subscriber identity module 108 is in a 4G standby state).

When the first subscriber identity module card 107 and the second subscriber identity module card 108 are both in a standby state, the first antenna set 220 and the second antenna set 240 may be controlled by using the control timing of the embodiment of the present application.

Referring to fig. 6, fig. 6 is a second timing diagram of the rf circuit according to the embodiment of the present disclosure. Other control sequences may be used when the first subscriber identity card 107 is in an active state and the second subscriber identity card 108 is in a standby state. Specifically, the transmission cycle also includes a first time period, a second time period, a third time period, and a fourth time period in succession.

In a first time period, the processing module 260 is configured to transmit a 5G radio frequency signal of the first subscriber identity card 107 through the first sub-antenna group 222 of the first antenna group 220, and transmit a 4G radio frequency signal of the first subscriber identity card 107 through the second sub-antenna group 224;

in the second time period, the processing module 260 is configured to transmit the 5G radio frequency signal of the first subscriber identity card 107 through the first antenna group 222 of the first antenna group 220 and transmit the 4G radio frequency signal through the second antenna group 224, and meanwhile, the processing module 260 is further configured to transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna group 240.

It should be noted that, in the embodiment of the present application, the first subscriber identity card 107 operates in an EN-DC state of NSA (i.e., LTE + NR dual connection), data is being uploaded and downloaded, the first antenna group 220 is occupied (for example, ANTs 0-3 of the first antenna group 220 are allocated to NR, ANT 0-3 are used as the first sub-antenna group 222, ANTs 4-5 of the first antenna group 230 are allocated to LTE, and ANT 4-5 are used as the second sub-antenna group 224), taking as an example that the first subscriber identity card 107 operates in B3+ N78, the N78 operation mode is 1T4R (T means transmission, R means reception), and the B3 operation mode is 1T2R, i.e., PRX + DRX. The first sub-antenna group 222 of the first antenna group 220 may be time-division multiplexed to implement 1T4R, and one antenna in the first sub-antenna group 222 may also be duplexer to implement transceiving multiplexing. Similarly, the second antenna group 224 of the first antenna group 220 may be time-division multiplexed to implement 1T2R, and one antenna in the second antenna group 224 may also be duplexer-multiplexed for transceiving. The second subscriber identity module card 108 is in a standby state, and needs to communicate with the base station at variable times, and the second antenna set 240 (e.g., LTE-ANT6, LTE-ANT7 antenna) may be used to transmit the 4G rf signal of the second subscriber identity module card 108.

Similarly, in the third time period, the processing module 260 is configured to transmit the 5G radio frequency signal of the first subscriber identity module 107 through the first sub-antenna group 222 of the first antenna group 220, and transmit the 4G radio frequency signal of the first subscriber identity module 107 through the second sub-antenna group 224; during the fourth time period, the processing module 260 is configured to transmit the 5G radio frequency signal of the first subscriber identity card 107 through the first antenna group 222 of the first antenna group 220 and transmit the 4G radio frequency signal of the first subscriber identity card 107 through the second antenna group 224, and meanwhile, the processing module 260 is further configured to transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna group 240. Can be reused in one transmission period.

It should be noted that, in the 5G network architecture of NSA, it is necessary to transmit a 5G radio frequency signal and a 4G radio frequency signal at the same time. Therefore, the first subscriber identity card 107 operates in the EN-DC state of NSA (i.e. LTE + NR dual connection), and needs to transmit the 5G rf signal and the 4G rf signal through the first antenna set 220 at the same time. The 4G rf signal transmitted by the first subscriber identity card 107 through at least two antennas in the first antenna set 220, such as the second antenna subset 224, may be a control signal in a 5G signal, but not a data signal, and may also include a control signal in the 5G signal and a data signal in the 4G signal.

Referring to fig. 7, fig. 7 is a third timing diagram of the rf circuit according to the embodiment of the present disclosure. Other control sequences may be used when both the first subscriber identity card 107 and the second subscriber identity card 108 are active. In any time period of the transmission cycle, the processing module 260 is configured to transmit the 5G radio frequency signal of the first subscriber identity card 107 through the first antenna group 222 of the first antenna group 220 and transmit the 4G radio frequency signal of the first subscriber identity card 107 through the second antenna group 224, and simultaneously transmit the 4G radio frequency signal of the second subscriber identity card 108 through the second antenna group 240.

It should be noted that, in the embodiment of the present application, the first subscriber identity card 107 operates in an EN-DC state of NSA (i.e., LTE + NR dual connectivity), data is being uploaded and downloaded, the first antenna group 220 is occupied (for example, ANTs 0-3 of the first antenna group 220 are allocated to NR, ANT 0-3 are used as the first sub-antenna group 222, ANTs 4-5 of the first antenna group 220 are allocated to LTE, and ANT 4-5 are used as the second sub-antenna group 224), taking as an example that the first subscriber identity card 107 operates in B3+ N78, the N78 operation mode is 1T4R (T means transmission, R means reception), and the B3 operation mode is 1T2R, i.e., PRX + DRX. The ANT 0-3 of the first antenna group 220 can be multiplexed in a time-sharing mode to achieve 1T4R, and one antenna in the ANT 0-3 can be multiplexed in a transceiving mode through a duplexer. Similarly, the ANTs 4-5 of the first antenna group 220 may be multiplexed in time division to realize 1T2R, and one of the ANTs 4-5 may also be multiplexed in transceiving by a duplexer. The second subscriber identity module card 108 is also in an operating state, and communication with the base station through the second antenna set 240 is required, so that the second antenna set 240 (e.g., LTE-ANT6, LTE-ANT7 antenna) may be used to transmit the 4G radio frequency signal of the second subscriber identity module card 108.

It should be noted that, in the 5G network architecture of NSA, it is necessary to transmit a 5G radio frequency signal and a 4G radio frequency signal at the same time. Therefore, the first subscriber identity card 107 operates in the EN-DC state of NSA (i.e. LTE + NR dual connection), and needs to transmit the 5G rf signal and the 4G rf signal through the first antenna set 220 at the same time. The first antenna sub-group 222 in the first antenna group 220 (e.g., the ANTs 0-3 in the first antenna group 220) may be used to transmit a 5G rf signal passing through the first subscriber identity card 107, and the second antenna sub-group 224 in the first antenna group 220 (e.g., the ANTs 4-5 in the first antenna group 220) may be used to transmit a 4G rf signal of the first subscriber identity card 107, where the 4G rf signal may be a control signal in the 5G signal without a data signal, and may include a control signal in the 5G signal and a data signal in the 4G signal.

Referring to fig. 8, fig. 8 is a schematic diagram of a second structure of the rf circuit according to the embodiment of the present disclosure. The rf circuit further includes a modem 230, wherein the first antenna set 220 and the second antenna set 240 are electrically connected to the modem 230, and the modem 230 is configured to process the rf signal according to the first subscriber identity card 107 and the second subscriber identity card 108.

The rf circuit may use a modem 230, wherein the first antenna set 220 and the second antenna set 240 are electrically connected to the modem 230, and the modem 230 is configured to process the rf signal according to the first subscriber identity card 107 and the second subscriber identity card 108 to generate a 5G signal and/or a 4G signal, transmit the 5G signal and the 4G signal through the first antenna set 220, and transmit the 4G signal through the second antenna set 240. The modem 230 may process 5G signals and may process 4G signals. For example, the modem 230 may process the 5G signal to generate a 5G data signal and a 4G control signal, and then transmit the 5G data signal through at least four antennas in the first antenna set 220, such as the first antenna sub-set 222, and transmit the 4G control signal through at least two antennas in the second antenna set, such as the second antenna sub-set 224. The modem 230 may also process the 4G signal to generate a 4G rf signal, and then transmit the 4G rf signal through the second antenna group 240.

The rf circuit may further include a front-end circuit 250, and the modem 230 is electrically connected to the first antenna set 220 and the second antenna set 240 through the front-end circuit 250. The front-end circuit 250 may include a power amplifier through which the modem 230 transmits radio frequency signals. The front-end circuit 250 may include a power amplifier through which the modem 230 transmits radio frequency signals. The front-end circuit 250 may also include a low noise amplifier through which the modem 230 receives radio frequency signals. A power amplifier corresponds to each transmit path and a low noise amplifier corresponds to each receive path. Each antenna may be multiplexed in both the transmit path and the receive path. For example, there are one power amplifier and one low noise amplifier for each antenna in the first antenna group, one low noise amplifier may be provided for the first antenna group, and one power amplifier may be provided for each antenna, and one of the low noise amplifiers may be selected to be connected as needed. The second antenna group may employ a similar structure to the first antenna group.

The rf circuit 200 may further include a baseband circuit, and the processing module 260 is connected to the modem 230 through the baseband circuit. The baseband circuit is used for processing communication data of the radio frequency circuit 200 and controlling the working state of each device in the radio frequency circuit 200 according to the interaction information with the base station or the network server. It is understood that the baseband circuit may be integrated into the processing module 260 of the electronic device 100, or may be independent of a separate processing circuit or processing chip.

The modem 230 is connected to the baseband circuit. The modem 230 is used for processing 5G signals. For example, the modem 230 may modulate upstream signals passing through the modem 230 and demodulate downstream signals passing through the modem 230.

It is understood that the uplink signal refers to a radio frequency signal transmitted by the radio frequency circuit 200 to the outside through the antenna, and the downlink signal refers to a radio frequency signal received by the radio frequency circuit 200 from the outside through the antenna.

It is understood that the 5g (nr) radio frequency signal of the first subscriber identity card refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through the information stored in the first subscriber identity card in the fifth generation mobile communication technology.

It is understood that the 4g (lte) radio frequency signal of the first subscriber identity card refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through the information stored in the first subscriber identity card in the fourth generation mobile communication technology.

It is understood that the 4g (lte) radio frequency signal of the second subscriber identity card refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through the information stored in the second subscriber identity card in the fourth generation mobile communication technology.

It is particularly pointed out that it is currently in the construction and development stage of 5G networks. 5G networks have specificity with respect to 4G networks.

Depending on the requirements of the communication protocol, a complete 4G network communication link requires at least 2 antennas to implement, and a complete 5G network communication link requires at least 4 antennas to implement. In a communication link formed by at least 4 antennas of a 5G network, it is necessary to maintain one antenna to implement SRS (Sounding Reference Signal) communication between an electronic device and a base station. That is, in a 5G network communication link between an electronic device and a base station, it is necessary to keep an antenna transmitting SRS signals to the base station, and the base station evaluates the quality of downlink channels between the base station and the electronic device through the received SRS signals, thereby facilitating the resource allocation of the downlink channels between the base station and the electronic device. However, according to the requirements of the communication protocol, the SRS signal needs to be switched between at least 4 antennas of the 5G network communication link. That is, the electronic device sequentially transmits the SRS signal to the base station in a time division manner through each of the at least 4 antennas of the 5G network communication link. The SRS signal does not carry communication content of communication between the user and other users, and is only used for the base station to evaluate the quality of the downlink channel.

For example, the processing module controls the modem to transmit an uplink Sounding Reference Signal (SRS) of the first subscriber identity module through the first transceiving antenna ANT0 for a first time period T1 in another transmission cycle; transmitting an uplink sounding reference signal of the first subscriber identity module card through a second transceiving antenna ANT1 during a second time period T2; transmitting an uplink sounding reference signal of the first subscriber identity module card through a third transceiving antenna ANT2 for a third time period T3; during a fourth time period T4, the uplink sounding reference signal of the first subscriber identity module card is transmitted through the fourth transceiving antenna ANT 3.

Therefore, in the radio frequency circuit, the SRS signal can be switched between the four transmitting/receiving antennas in the first antenna group. That is, the SRS signal is sequentially transmitted to the base station through the four transceiving antennas in a time division manner, and when one of the four transceiving antennas is used for transmitting the SRS signal, the other three antennas realize transmission of the communication content of the user between the electronic device and the base station.

Therefore, coexistence of a 5G network and a 4G network under two SIM card situations is a problem to be solved urgently in the industry, and currently, no good solution exists.

In the process of constructing the 5G network, according to the requirement of the communication protocol, a 5G network architecture of an independent networking (SA) or a 5G network architecture of a Non-independent Networking (NSA) may be adopted. In the 5G network architecture of NSA, it is necessary to transmit 5G signals and 4G signals at the same time. That is, in the 5G network architecture of NSA, the 5G radio frequency signals include 4G signal streams and 5G signal streams.

Referring to fig. 9, fig. 9 is a schematic flowchart of a radio frequency circuit control method according to an embodiment of the present disclosure. The embodiment of the present application further provides a radio frequency circuit control method, where the radio frequency circuit control method is applied to the radio frequency circuit and the electronic device in any of the above embodiments, for example, the radio frequency circuit includes a first antenna group and a second antenna group, where the first antenna group includes at least six antennas; the second antenna group includes at least two antennas.

The first antenna group may include a first antenna sub-group and a second antenna sub-group, the first antenna sub-group may include at least four antennas, and the processing module is configured to transmit a 5G radio frequency signal of the first subscriber identity module card through the first antenna sub-group; the second sub-antenna group may include at least two antennas, and the processing module is configured to transmit a 4G radio frequency signal of the first subscriber identity module card through the second sub-antenna group.

The transmission cycle includes a first period, a second period, a third period, and a fourth period in succession. The method specifically comprises the following steps:

301, acquiring a first state of a first user identification card and a second state of a second user identification card;

and 302, controlling the first antenna group and the second antenna group according to the first state and the second state, so that the first antenna group transmits the 5G radio frequency signal and the 4G radio frequency signal of the first subscriber identity module card, and the second antenna group transmits the 4G radio frequency signal of the second subscriber identity module card.

And transmitting the 5G radio frequency signal and the 4G radio frequency signal of the first user identification card through the first antenna group, and transmitting the 4G radio frequency signal of the second user identification card through the second antenna group. The 5G communication of the first user identification card can be realized, the 4G communication of the second user identification card can also be realized, and double-card double-pass based on the 5G communication technology is realized.

The transmission cycle comprises a first time period and a second time period which are continuous; controlling the first antenna group and the second antenna group according to the first state and the second state may specifically include:

when the first state is a standby state and the second state is a standby state, transmitting a 5G radio frequency signal and a 4G radio frequency signal of the first user identity identification card through the first antenna group in a first time period; and transmitting the 4G radio frequency signal of the second user identification card through the second antenna group in a second time period.

The first user identification card is in a standby state, the second user identification card is also in a standby state, and at the moment, double-card double standby based on the 5G communication technology can be realized through the first antenna group and the second antenna group (the first user identification card is in 5G standby, and the second user identification card is in 4G standby).

It should be noted that the transmission cycle further includes a third time period and a fourth time period, and the third time period and the fourth time period have the same control method as the first time period and the second time period.

when the first state is the working state and the second state is the standby state, the 5G radio frequency signal and the 4G radio frequency signal of the first user identity identification card are transmitted through the first antenna group in the first time period, the 5G radio frequency signal and the 4G radio frequency signal of the first user identity identification card are transmitted through the first antenna group in the second time period, and meanwhile, the 4G radio frequency signal of the second user identity identification card is transmitted through the second antenna group.

The first subscriber identity module card 107 operates in an EN-DC state of NSA (i.e. LTE + NR dual connectivity), data is being uploaded and downloaded, the first antenna group 220 is occupied (e.g. ANTs 0-3 of the first antenna group 220 are allocated to NR, ANT 0-3 are used as a first sub-antenna group; ANTs 4-5 of the first antenna group 230 are allocated to LTE, ANT 4-5 are used as a second sub-antenna group 224), taking the example that the first subscriber identity module card 107 operates in B3+ N78, the N78 operation mode is 1T4R (T means transmission, R means reception), and the B3 operation mode is 1T2R, i.e. PRX + DRX. The first sub-antenna group 222 in the first antenna group 220 may be time-division multiplexed to implement 1T4R, and one antenna in the first sub-antenna group 222 may also be duplexer to implement transceiving multiplexing. Similarly, the second antenna group 224 in the first antenna group 220 may be time-division multiplexed to implement 1T2R, and one antenna in the second antenna group 224 may also be duplexer-multiplexed for transceiving. The second subscriber identity module card 108 is in a standby state, and needs to communicate with the base station at variable times, and the second antenna set 240 (e.g., LTE-ANT6, LTE-ANT7 antenna) may be used to transmit the 4G rf signal of the second subscriber identity module card 108.

Wherein controlling the first antenna group and the second antenna group according to the first state and the second state may further specifically include:

and when the first state is a working state and the second state is a working state, in any time period in a transmission cycle, transmitting the 5G radio frequency signal and the 4G radio frequency signal of the first user identity identification card through the first antenna group, and simultaneously transmitting the 4G radio frequency signal of the second user identity identification card through the second antenna group.

It should be noted that, in the embodiment of the present application, the first subscriber identity card 107 operates in an EN-DC state of NSA (i.e., LTE + NR dual connection), data is being uploaded and downloaded, the first antenna group 220 is occupied (for example, ANTs 0-3 of the first antenna group 220 are allocated to NR, ANT 0-3 are used as a first sub-antenna group; ANTs 4-5 of the first antenna group 220 are allocated to LTE, and ANT 4-5 are used as a second sub-antenna group 224), taking as an example that the first subscriber identity card 107 operates in B3+ N78, the operation mode of N78 is 1T4R (T means transmission, R means reception), and the operation mode of B3 is 1T2R, i.e., PRX + DRX. The ANT 0-3 of the first antenna group 220 can be multiplexed in a time-sharing mode to achieve 1T4R, and one antenna in the ANT 0-3 can be multiplexed in a transceiving mode through a duplexer. Similarly, the ANTs 4-5 of the first antenna group 220 may be multiplexed in time division to realize 1T2R, and one of the ANTs 4-5 may also be multiplexed in transceiving by a duplexer. The second subscriber identity module card 108 is also in an operating state, and communication with the base station through the second antenna set 240 is required, so that the second antenna set 240 (e.g., LTE-ANT6, LTE-ANT7 antenna) may be used to transmit the 4G radio frequency signal of the second subscriber identity module card 108.

Illustratively, as shown in fig. 10, the electronic device in the embodiment of the present application displays a graphical user interface schematic diagram when executing the radio frequency circuit control method. When the first user identification card and the second user identification card are both in a working state, whether the first user identification card and the second user identification card simultaneously have incoming calls or not is judged, if the two user identification cards both have incoming calls, the electronic equipment can automatically display incoming call information in a split screen mode, and a user can select to respond to the incoming call of only one user identification card or respond to the incoming calls of the two user identification cards simultaneously according to actual conditions. For example, when an incoming call of a first subscriber identity card is associated with an incoming call of a second subscriber identity card, a user can simultaneously respond to the incoming calls of the two subscriber identity cards, so that an incoming call object from the first subscriber identity card, an incoming call object from the second subscriber identity card and the user can form a communication group, and the three can communicate with each other, for example, the communication group can be used for a group conference, a friend chat and other scenes. Therefore, the electronic equipment can realize the multi-person conversation function under the condition of no data transmission signal.

For example, the user may also classify two user identification cards according to time, for example, a first user identification card may be used for responding to the data service of the working time, a second user identification card may be used for responding to the data service of the working rest time, and the electronic device preferentially responds to the data service of the corresponding time end according to the difference of the time periods. For example, when an incoming call comes in from both the first user identification card and the second user identification card during work hours, the incoming call request of the first user identification card is responded preferentially; and in the working vacation time, when the first user identification card and the second user identification card both have incoming calls, preferentially responding to the incoming call request of the second user identification card. Therefore, the intelligence of double-card double-pass can be improved.

For example, a user may set to use a first subscriber identity module card during data transmission, use a second subscriber identity module card during mobile data services such as call services, and transmit data resources of the first subscriber identity module card through the first antenna group, while responding to the mobile data services of the second subscriber identity module card through the second antenna group. For example, a user can transmit a 5G radio frequency signal of a first user identification card through the first antenna group, so that the user can play games on the internet, respond to incoming calls of a second user identification card through the second antenna group, and use the dual-card dual-pass function of the electronic equipment to realize playing games and listening to calls. For example, a user can input a 5G radio frequency signal of a first user identification card through the first antenna group, so that the user can communicate with the internet of things to realize automatic driving, respond to an incoming call of a second user identification card through the second antenna group, and answer a call while driving by using a double-card double-pass function of the electronic equipment.

It should be noted that, in the 5G network architecture of NSA, it is necessary to transmit a 5G radio frequency signal and a 4G radio frequency signal at the same time. Therefore, the first subscriber identity card 107 operates in the EN-DC state of NSA (i.e. LTE + NR dual connection), and needs to transmit the 5G rf signal and the 4G rf signal through the first antenna set 220 at the same time. Wherein, the four antennas in the first antenna group 220 (e.g., ANT 0-3, ANT 0-3 of the first antenna group 220 as the first sub-antenna group 222) may be used to transmit the 5G rf signal passing through the first subscriber identity card 107, and the two antennas in the first antenna group 220 (e.g., ANT 4-5, ANT 4-5 of the first antenna group 220 as the second sub-antenna group 224) may be used to transmit the 4G rf signal of the first subscriber identity card 107, wherein the 4G rf signal may be the control signal in the 5G signal but not the data signal, and may also include the control signal in the 5G signal and the data signal of the 4G signal.

when the first user identification card and the second user identification card are both in a working state, detecting the network connection state of a Wi-Fi signal device in the electronic equipment;

and if the Wi-Fi signal device is in a connection state, controlling the Wi-Fi signal device to perform data transmission, and controlling the first user identification card and the second user identification card to be used for responding to the call service.

Or

if the Wi-Fi signal device is in a connection state, acquiring the data volume of data to be transmitted of a 5G radio frequency signal of the first user identity identification card;

judging whether the data volume of the data to be transmitted is larger than a first preset value or not;

and if the data volume of the data to be transmitted is larger than a first preset value, controlling the first antenna group to transmit the data to be transmitted of the first user identity identification card, and transmitting the data to be transmitted by using the 5G radio frequency signal of the first antenna group. That is, when the data volume of the data to be transmitted is large, the data to be transmitted is transmitted by using the first antenna group, and the data to be transmitted is transmitted at a high transmission rate of the 5G NR network.

For example, when a user needs to download a full-high-definition movie, because the data volume of the full-high-definition movie is usually large, some full-high-definition movies may even reach 40G, at this time, the electronic device may control the first antenna group to respond to the transmission instruction, the first antenna group is accessed to the 5G NR network through the mutual cooperation of the first antenna group and the second antenna group, and the full-high-definition movie is downloaded by using the 5G NR network. Because the transmission rate of the 5G NR network is fast, for example, the transmission rate of the 5G NR network can reach 10Gbps, which means that the electronic device can complete downloading of a full high-definition movie within four seconds, and user experience can be greatly improved.

And if the data volume of the data to be transmitted is smaller than a first preset value and larger than a second preset value, controlling the WIFI signal device to transmit the data to be transmitted of the first user identification card, wherein the first antenna group is used for responding to the call service of the first user identification card, and the second antenna group is used for transmitting the data to be transmitted and the call service of the second user identification card. Wherein the value of the second preset value is smaller than the first preset value. It can be understood that when the data volume of the data to be transmitted is smaller than the first preset value and larger than the second preset value, the data to be transmitted can be divided into two parts, one part of the data is transmitted by the WIFI signal device, the other part of the data is transmitted by the 4G radio frequency signal of the second user identity identification card, the data to be transmitted is transmitted by the WIFI signal device and the 4G radio frequency signal of the second user identity identification card at the same time, the transmission rate can be guaranteed, and the power consumption can be reduced.

If the data volume of the data to be transmitted is smaller than a second preset value, controlling the WIFI signal device to transmit the data to be transmitted of the first user identification card and the data to be transmitted of the second user identification card, wherein the first antenna group is used for keeping contact with a base station, and when the first user identification card has a mobile service such as a call, the first antenna group can be used for responding to the mobile service; the second antenna group is also used for keeping contact with the base station, and when the second subscriber identity card has mobile services such as call calling, the second antenna group can be used for responding to the mobile services.

It can be understood that, when the data volume is relatively small, the electronic device may control the WIFI signaling apparatus to transmit data, and contact the base station through the first antenna group, and when there is a call, the first antenna group may be used to respond to the call service. Due to the fast transmission rate of the 5G NR network, the electronic device consumes more power when using the 5G NR network for data transmission. When the data volume to be transmitted is small, the WIFI signal device and/or the second antenna group are/is adopted for data transmission, and the power consumption of the electronic equipment can be reduced.

acquiring a first data volume of a 4G radio frequency signal of a second user identity identification card to be transmitted;

when the first data volume is smaller than a first threshold value, acquiring a second data volume of the 5G radio frequency signal of the first user identity identification card to be transmitted;

when the second data volume is smaller than a second threshold value, transmitting a data signal of the first user identity identification card through a first antenna group in the first antenna group, transmitting a control signal of the first user identity identification card through a second antenna group in the first antenna group, and transmitting a 4G radio frequency signal of the second user identity identification card through the second antenna group;

when the second data volume is not less than a second threshold value, dividing the data signal of the 5G radio frequency signal of the first user identity recognition card to be transmitted into a first part and a second part, transmitting the first part of the first user identity recognition card through the first antenna group, transmitting the second part of the first user identity recognition card through the second antenna group, and transmitting the 4G radio frequency signal of the second user identity recognition card through the second antenna group;

or

When the second data volume is not less than a second threshold value, transmitting a receiving radio frequency signal of the first user identity identification card through the first antenna group, transmitting a transmitting radio frequency signal of the first user identity identification card through the second antenna group, and transmitting a 4G radio frequency signal of the second user identity identification card through the second antenna group;

when the first data volume is not less than the first threshold value, transmitting a data signal of the first user identification card through a first antenna group in the first antenna group, transmitting a control signal of the first user identification card through a second antenna group in the first antenna group, and transmitting a 4G radio frequency signal of the second user identification card through the second antenna group.

When the first data volume for transmitting the second user identification card is smaller than a first threshold value, checking a second data volume for transmitting the first user identification card, and when the second data volume is also smaller than a second threshold value, a first sub-antenna group in a first antenna group is used for transmitting a data signal of a 5G signal of the first user identification card, a second sub-antenna group in the first antenna group is used for controlling the transmission of the 5G signal of the first user identification card, and the second antenna group is mainly used for transmitting a 4G signal of the second user identification card; when the second data volume is larger than a second threshold value, dividing the data signal of the first subscriber identity module card into two parts, wherein one part is transmitted through the first antenna group, and the other part is transmitted through the second antenna group; when the second data volume is larger than the second threshold, because the received data volume is generally much larger than the transmitted data volume, the transmitted radio frequency signal of the first subscriber identity card can be transmitted through the second antenna group, and the received radio frequency signal of the first subscriber identity card can be transmitted through the first antenna group. The transmission efficiency of the whole radio frequency circuit can be optimized.

and dividing the data signal of the radio frequency signal of the first subscriber identity identification card 5G to be transmitted into a first part and a second part according to the first data volume and the second data volume.

The larger the first data amount is, the smaller the proportion of the second portion is. The correspondence table of the proportions of the first data amount and the second portion may be obtained through big data analysis in advance. And a corresponding relation table of the proportion of the first data quantity and the second part can be obtained through user historical data analysis.

Dividing the data signal of the 5G radio frequency signal of the first subscriber identity module card to be transmitted into a first part and a second part may specifically include:

and dividing the data signal of the radio frequency signal of the first subscriber identity identification card 5G to be transmitted into a first part and a second part according to the signal intensity of the current first antenna group and the second antenna group.

The larger the signal strength of the first antenna group is, the smaller the proportion of the second part is, and the larger the signal strength of the second antenna group is, the larger the proportion of the second part is. The correspondence table between the signal intensity of the first antenna group and the ratio of the second part and the correspondence table between the signal intensity of the second antenna group and the ratio of the second part may be obtained through big data analysis in advance. And a corresponding relation table of the signal intensity of the first antenna group and the proportion of the second part and a corresponding relation table of the signal intensity of the second antenna group and the proportion of the second part can be obtained through user historical data analysis.

according to the current state of the electronic equipment, dividing a data signal of a 5G radio frequency signal of the first user identity identification card to be transmitted into a first part and a second part.

The current state of the electronic equipment can be battery power, the lower the battery power is, the larger the proportion of the second part is, the whole power consumption of the radio frequency circuit can be reduced, and the standby time is prolonged. The electronic device state can be an operating memory, and the higher the utilization rate of the operating memory is, the larger the proportion of the second part is, so that the overall power consumption of the radio frequency circuit can be reduced.

For example, the electronic device may obtain a first signal value and a current electric quantity value which are currently received, calculate a signal connection threshold according to the current electric quantity value and the first signal value, search for a 5G network signal, so that the base station obtains a first 5G signal value, report the signal connection threshold to the base station, and use that when the first 5G signal value is greater than the signal connection threshold, the second part is greater than the first part, access the 5G NR network through the first antenna group, transmit the second part through the 5G NR network, access the 4G LTE network through the second antenna group, and transmit the first part through the 4G LTE network. And when the first 5G signal value is smaller than the signal connection threshold value, the second part is smaller than the first part, the 5G NR network is accessed through the first antenna group, the second part is transmitted through the 5G NR network, the 4G LTE network is accessed through the second antenna group, and the first part is transmitted through the 4G LTE network.

The base station in the embodiment of the application may determine whether the electronic device has a condition of connecting to the 5G network according to the signal connection threshold and the current first 5G signal value of the electronic device, for example, if-96 dBm of the first 5G signal is less than-94.5 dBm of the connection threshold, the electronic device does not have the condition of connecting to the 5G network.

When the first 5G signal-96 dBm is equal to or larger than a connection threshold value-94.5 dBm, reducing the proportion of the second part and increasing the proportion of the first part, mainly accessing to a 4G LTE network through a second antenna group, and carrying out data transmission by utilizing the 4G LTE network; when the 5G network signal of the position where the electronic device is located is greater than the signal connection threshold and is located in a better signal environment, the proportion of the second part is increased and the proportion of the first part is reduced, the electronic device is mainly accessed to the 5G NR network through the first antenna group, and data transmission is carried out by using the 5G NR network. The embodiment of the application can enable the electronic equipment to mainly use the 5G NR network for data transmission under the condition of low electric quantity and in a better signal environment, so that the signal transmitting power of the electronic equipment is reduced, and the power consumption of the electronic equipment is reduced.

Wherein the RSRPc is a signal connection threshold, which can be understood as a signal return value of the base station reported by the electronic device, the base station determines whether the electronic device has a condition for connecting to the 5G network according to the return value, the RSRP ' can be an RSRP ' value measured by the current electronic device on the basis of a 4G network according to a signal of the base station, the RSRP ' can also be an RSRP ' value returned by the base station for the electronic device, which is used for measuring the signal quality of the current electronic device on the 4G network, and B is a current power value of the electronic device, for example, when the RSRP ' value measured by the electronic device on the basis of a 4G network according to a signal of the base station is-96 dBm, and the RSRP value of-96 dBm belongs to a level of poor coverage, under which outdoor voice service can be called but the call success rate is low, the call drop rate is high, the indoor service can not initiate the service basically, if the signal connection threshold (return value is adjusted, the 5G network is directly searched, and the 5G network is connected under the poor condition, because the signal under the RSRP 'value is poor, namely the electronic equipment is far away from the base station, the propagation loss is larger, the electronic equipment needs to have larger power consumption for transmitting the 5G signal, and the power consumption is too fast under the condition that the electric quantity of the electronic equipment is low, so that a certain influence is caused to a user, the adjustment is needed according to the current electric quantity B, when the current electric quantity is 50%, the RSRP' is equal to-96 dBm, and the B is equal to 0.5, which are substituted into a formula, so that the RSRP pc is equal to-94.5 dBm, and-94.5 dBm can be calculated, and belong to the level of general signal coverage.
