The cover plate 102 is mounted on the middle frame 103, and the cover plate 102 covers the display screen 101 to protect the display screen 101 from being scratched or damaged by water. The cover 102 may be a transparent glass cover, so that a user can see the contents displayed on the display 101 through the cover 102. It is understood, however, that the cover plate 102 may be a glass cover plate of sapphire material.

The middle frame 103 may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. 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. For example, the display screen 101 may be mounted on the housing. In addition, functional components such as a camera, a receiver, a circuit board, and a battery of the electronic apparatus 100 may be mounted on the center frame 103 to be fixed. It is understood that the material of the middle frame 103 may include metal or plastic.

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. In addition, one or more of a microphone, a speaker, a receiver, an earphone interface, a camera, an acceleration sensor, a gyroscope, a processor, and other functional components may be integrated on the circuit board 104. Meanwhile, the display screen 101 may be electrically connected to the circuit board 104 to control display of the display screen 101 by a processor on the circuit board 104.

The battery 105 is mounted inside a casing formed by the middle frame 103 and the rear cover 106 together. For example, the battery 105 may be mounted on the middle frame 103. Meanwhile, the battery 105 is electrically connected to the circuit board 104 to enable the battery 105 to supply power to the electronic device 100. The circuit board 104 may be provided thereon with a power management circuit. The power management circuit is used to distribute the voltage provided by the battery 105 to the various electronic components in the electronic device 100.

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

The first SIM card 107 is mounted inside the casing formed by the middle frame 103 and the rear cover 106 together. For example, the first SIM card 107 is mounted on the middle frame 103. The first SIM card 107 may serve as an information storage for storing identification information of the user, such as a telephone number for representing the identity of the user. In addition, the first SIM card 107 may also be used to store personal information of the user, such as a key used to encrypt voice contents at the time of a voice call, a phone book of the user, and the like. Among them, the SIM card is also called a subscriber identity card, a smart card, and the like.

It should be noted that, after the first SIM 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 SIM card 107.

A second SIM card 108 is also mounted inside the casing formed by the middle frame 103 and the back cover 106 together. For example, a second SIM card 108 is also mounted on the middle frame 103. The second SIM 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 subscriber identity information stored on the second SIM card 108 is different from the subscriber identity information stored on the first SIM card 107. For example, the first SIM card 107 stores first identification information of the user, such as a first phone number for indicating the identity of the user; the second SIM card 108 stores second identification information of the user, for example, a second telephone number for indicating the identity of the user. In addition, the user personal information stored on the second SIM card 108 may be the same as or partially the same as or different from the user personal information stored on the first SIM card 107.

It should be noted that, after the second SIM 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 SIM card 108.

In the embodiment of the present application, the circuit board 104 is provided with a radio frequency circuit 200. The rf circuit 200 is used to enable wireless communication between the electronic device 100 and a base station or other electronic devices. Referring to fig. 3, fig. 3 is a schematic structural diagram of a radio frequency circuit 200 according to an embodiment of the present disclosure.

The radio frequency circuit 200 comprises a baseband circuit 201, a modem 202 and at least eight antennas 203. Wherein at least eight means eight or more, such as eight, nine, ten, etc.

The baseband circuit 201 is used for processing communication data of the rf circuit 200 and controlling the operating state of each device in the rf circuit 200 according to the interaction information with the base station or the network server. It is understood that the baseband circuit 201 may be integrated into the processor of the electronic device 100, or may be independent of a separate processing circuit or processing chip.

It can be understood that the first SIM card 107 and the second SIM card 108 of the electronic device 100 can be electrically connected to the baseband circuit 201, so that the radio frequency circuit 200 can communicate with a base station or other electronic devices through the user identification information and the user personal information stored in the first SIM card 107 and the second SIM card 108.

The modem 202 is connected to the baseband circuit 201. The modem 202 is configured to process a first 5G radio frequency signal of the first SIM card 107 and a second 5G radio frequency signal of the second SIM card 108. For example, the modem 202 may modulate the uplink 5G radio frequency signal of the first SIM card 107, demodulate the downlink 5G radio frequency signal of the first SIM card 107, modulate the uplink 5G radio frequency signal of the second SIM card 108, and demodulate the downlink 5G radio frequency signal of the second SIM card 108.

The first 5G radio frequency signal refers to a 5G radio frequency signal when the radio frequency circuit 200 communicates with a base station or other electronic devices through information such as user identification information and user personal information stored in the first SIM card 107. The second 5G radio frequency signal refers to a 5G radio frequency signal when the radio frequency circuit 200 communicates with a base station or other electronic devices through information such as user identification information and user personal information stored in the second SIM card 108.

It can be understood that the uplink 5G radio frequency signal refers to a 5G radio frequency signal transmitted by the radio frequency circuit 200 to the outside through an antenna, and the downlink 5G radio frequency signal refers to a 5G radio frequency signal received by the radio frequency circuit 200 from the outside through an antenna.

With the development of wireless communication technology, communication systems that perform communication in various wireless communication modes have appeared in the field of wireless communication. For example, wireless communication modes such as Long Term Evolution (LTE), Wideband Code Division Multiple Access (WCDMA), time division synchronous code division multiple access (TD-SCDMA), New generation mobile communication (New Radio, NR), and the like. Among them, Long Term Evolution (LTE), Wideband Code Division Multiple Access (WCDMA), and time division synchronous code division multiple access (TD-SCDMA) belong to The 4th Generation Mobile Communication Technology (4G), and new Generation Mobile Communication (NR) belongs to The 5th Generation Mobile Communication Technology (5G).

It is understood that the first 5G rf signal of the first SIM card 107 and the second 5G rf signal of the second SIM card 108 are both rf signals when performing communication using the fifth generation mobile communication technology.

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 the SA, only 5G radio frequency signals need to be transmitted. In the 5G network architecture of NSA, it is necessary to transmit 5G radio frequency signals and 4G radio frequency signals simultaneously.

In this embodiment, the first 5G radio frequency signal of the first SIM card 107 is a 5G radio frequency signal of an independent networking, that is, a 5G radio frequency signal of an SA mode. The second 5G radio frequency signal of the second SIM card is also a 5G radio frequency signal of an independent networking, that is, a 5G radio frequency signal of an SA mode.

Each of the at least eight antennas 203 is connected to the modem 202. The at least eight antennas 203 are used for transmitting a first 5G rf signal of the first SIM card 107 and a second 5G rf signal of the second SIM card 108. Each of the antennas 203 may be configured to transmit the first 5G radio frequency signal or transmit the second 5G radio frequency signal. It is understood that transmitting the 5G radio frequency signal includes at least one of transmitting the 5G radio frequency signal, receiving the 5G radio frequency signal, and transmitting and receiving the 5G radio frequency signal.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating a first signal transmission in the rf circuit 200 according to the embodiment of the present disclosure.

The at least eight antennas 203 may be, for example, eight antennas such as ANT1, ANT2, ANT3, ANT4, ANT5, ANT6, ANT7, and ANT 8. Four first antennas of the eight antennas are used for transmitting the first 5G radio frequency signals, and four second antennas of the eight antennas are used for transmitting the second 5G radio frequency signals. Wherein the four first antennas and the four second antennas are different antennas.

For example, ANT1, ANT2, ANT3, ANT4 may be the first antenna. The four first antennas ANT1, ANT2, ANT3, ANT4 may be used to transmit the first 5G radio frequency signal, for example, transmit the first 5G radio frequency signal, receive the first 5G radio frequency signal, or both transmit and receive the first 5G radio frequency signal. ANT5, ANT6, ANT7, ANT8 may be the second antenna. The four second antennas ANT5, ANT6, ANT7, ANT8 may be used to transmit the second 5G radio frequency signal, such as to transmit the second 5G radio frequency signal, receive the second 5G radio frequency signal, or both transmit and receive the second 5G radio frequency signal.

The data volume transmitted by the first 5G radio frequency signal is larger than that transmitted by the second 5G radio frequency signal. The total transmission efficiency of the four first antennas to the 5G radio frequency signals is greater than that of the four second antennas to the 5G radio frequency signals, so that the transmission requirement of the first 5G radio frequency signals on large data volume is met, and the requirement of the second 5G radio frequency signals on simultaneous data transmission is met.

It should be noted that the four first antennas and the four second antennas are not fixed. In practical applications, the electronic device 100 may dynamically allocate the eight antennas ANT1, ANT2, ANT3, ANT4, ANT5, ANT6, ANT7, and ANT8 according to the size of the data volume transmitted by the first 5G radio frequency signal and the size of the data volume transmitted by the second 5G radio frequency signal, so as to select four first antennas with higher transmission efficiency from the eight antennas for transmitting the first 5G radio frequency signal, and select another four second antennas for transmitting the second 5G radio frequency signal.

In addition, it should be noted that the transmission efficiency of the antenna is related to the parameters of the antenna itself and the state of the antenna. For example, the transmission efficiency of an antenna is related to parameters and states such as the gain of the antenna itself, the radiation length of the antenna, the frequency of a radio frequency signal transmitted by the antenna, and the radiation direction of the antenna. Moreover, the transmission efficiency of each antenna for the radio frequency signal is not fixed, but changes with the change of parameters or states such as the use environment, the frequency of the transmitted radio frequency signal and the like.

It can be understood that, the amount of data transmitted by the first 5G radio frequency signal is greater than the amount of data transmitted by the second 5G radio frequency signal, which means that the amount of data generated when the electronic device 100 communicates with the base station through the first SIM card 107 is greater than the amount of data generated when the electronic device communicates with the base station through the second SIM card 108.

When the first 5G radio frequency signal of the first SIM card 107 includes first communication service data, the second 5G radio frequency signal of the second SIM card 108 includes second communication service data, and the data volume of the first communication service data is greater than the data volume of the second communication service data, the data volume transmitted by the first 5G radio frequency signal is greater than the data volume transmitted by the second 5G radio frequency signal. For example, the first communication service data may be data generated by a video call, and the second communication service data may be data generated by a voice chat; for another example, the first communication service data may be data generated when a picture is uploaded or downloaded, and the second communication service data may be data generated when a text message is sent.

When the first 5G radio frequency signal of the first SIM card 107 includes communication service data and the second 5G radio frequency signal of the second SIM card 108 does not include communication service data, the data volume transmitted by the first 5G radio frequency signal is also greater than the data volume transmitted by the second 5G radio frequency signal. For example, when the electronic device 100 performs a voice call service through the first SIM card 107 and the second SIM card 108 is in a standby state, the data amount transmitted by the first 5G radio frequency signal is greater than the data amount transmitted by the second 5G radio frequency signal.

When neither the first 5G radio frequency signal of the first SIM card 107 nor the second 5G radio frequency signal of the second SIM card 108 includes communication service data, the data volume transmitted by the first 5G radio frequency signal may also be greater than the data volume transmitted by the second 5G radio frequency signal. For example, when the electronic device 100 receives heartbeat packet data issued by a base station at a faster frequency through the first SIM card 107 and receives heartbeat packet data issued by a base station at a slower frequency through the second SIM card 108, the data volume transmitted by the first 5G radio frequency signal is greater than the data volume transmitted by the second 5G radio frequency signal.

It should be noted that the communication service data refers to data transmitted by the electronic device through the radio frequency circuit 200 in the process of the user communicating with other users through the base station. For example, in the process of sending a video call or a voice call to another user through the base station, in the process of making a video call or a voice call with another user through the base station, in the process of sending picture information or text information to another user through the base station, in the process of receiving picture information or text information from another user through the base station, in the process of downloading a file from a server through the base station, or in the process of uploading a file to a server through the base station, data transmitted by the electronic device through the radio frequency circuit 200 may be understood as communication service data.

In addition, excluding the communication service data refers to data transmitted between the radio frequency circuit 200 and the base station, which is transmitted by the electronic device through the connection established between the radio frequency circuit 200 and the base station, but the user does not communicate with other users through the base station. For example, in the standby process of the electronic device, data transmitted when the base station receives a heartbeat packet issued at regular or irregular time by the radio frequency circuit 200, data transmitted when the radio frequency circuit 200 receives a telephone call of another user through the base station, and data transmitted when the radio frequency circuit 200 sends an SRS (Sounding Reference Signal) Signal to the base station may be understood as data that does not include a communication service.

It can be understood that the amount of data generated by the electronic device when performing communication service through the SIM card is usually relatively large, and the amount of data generated when not performing communication service is usually relatively small. Also, the size of the generated data amount is different for different communication services.

The radio frequency circuit 200 provided by the embodiment of the application, through carrying out dynamic allocation to eight antennas, make four first antennas that transmission efficiency is big be used for transmitting the big first 5G radio frequency signal of data volume, and four second antennas are used for transmitting the less second 5G radio frequency signal of data volume, both can satisfy first SIM card 107, second SIM card 108 in the data transmission demand of dual-card dual-standby in-process, can satisfy the data transmission demand at dual-card dual-pass in-process again, carry out resource allocation to eight antennas simultaneously, make the transmission efficiency maximize of eight antennas, thereby can improve the data transmission efficiency of radio frequency circuit 200 in the electronic equipment.

In some embodiments, referring to fig. 5, fig. 5 is a schematic diagram of a second signal transmission in the rf circuit 200 according to an embodiment of the present disclosure. It should be noted that, in fig. 5 and the drawings appearing below, the SIM1 shown in the drawing represents the first 5G radio frequency signal of the first SIM card 107, and the SIM2 represents the second 5G radio frequency signal of the second SIM card 108.

Wherein, when the four first antennas ANT1, ANT2, ANT3, ANT4 transmit the first 5G rf signal of the first SIM card 107, the first 5G rf signal may be periodically transmitted with a certain transmission period. The four second antennas ANT5, ANT6, ANT7, ANT8 may also periodically transmit the second 5G rf signal at the transmission period when transmitting the second 5G rf signal of the second SIM card 108. The transmission cycle may include a plurality of timings, for example, the transmission cycle may include four timings, i.e., T1, T2, T3, and T4.

When the first 5G radio frequency signal includes communication traffic data, the four first antennas ANT1, ANT2, ANT3, ANT4 are used to transmit the first 5G radio frequency signal at each timing of each transmission period. That is, the four first antennas ANT1, ANT2, ANT3, ANT4 are used to continuously transmit the first 5G radio frequency signal in each transmission period. For example, the four first antennas ANT1, ANT2, ANT3, ANT4 are used to transmit the first 5G radio frequency signal at four timings of T1, T2, T3, T4, etc. of each transmission period.

It will be appreciated that when the first 5G radio frequency signal comprises communication traffic data, it is necessary to both receive the 5G radio frequency signal and transmit the 5G radio frequency signal. Therefore, the four first antennas ANT1, ANT2, ANT3, ANT4 may be used to receive the first 5G radio frequency signal in each of the transmission periods. Meanwhile, at least one first antenna of the four first antennas ANT1, ANT2, ANT3, ANT4 is also used to transmit the first 5G radio frequency signal every the transmission period. For example, the first antenna ANT1 may be used to transmit the first 5G radio frequency signal in each transmission period to implement 1T4R (where T refers to transmit and R refers to receive) of the first 5G radio frequency signal. Alternatively, the first antennas ANT1, ANT2 may be both configured to transmit the first 5G radio frequency signal in each transmission period to implement 2T4R of the first 5G radio frequency signal.

In some embodiments, with continued reference to fig. 5, when the second 5G radio frequency signal also includes communication traffic data, the four second antennas ANT5, ANT6, ANT7, ANT8 are used to transmit the second 5G radio frequency signal at each timing of each of the transmission periods. That is, the four second antennas ANT5, ANT6, ANT7, ANT8 are used to continuously transmit the second 5G radio frequency signal in each transmission period. For example, the four second antennas ANT5, ANT6, ANT7, ANT8 are used to transmit the second 5G radio frequency signal at four timings T1, T2, T3, T4, etc. of each transmission period.

Similarly, when the second 5G rf signal includes communication service data, the 5G rf signal needs to be received and the 5G rf signal needs to be transmitted at the same time. Therefore, the four second antennas ANT5, ANT6, ANT7, ANT8 may be used to receive the second 5G radio frequency signal in each transmission period. Meanwhile, at least one of the four second antennas ANT5, ANT6, ANT7, ANT8 is also used to transmit the second 5G radio frequency signal every the transmission period. For example, the second antenna ANT4 may be used to transmit the second 5G radio frequency signal in each transmission period to implement 1T4R of the second 5G radio frequency signal. Alternatively, the second antennas ANT4, ANT5 may be both configured to transmit the second 5G radio frequency signal in each transmission period, so as to implement 2T4R of the second 5G radio frequency signal.

Thus, a double-card double-pass of the first SIM card 107 and the second SIM card 108 in the electronic device 100 may be realized by the four first antennas ANT1, ANT2, ANT3, ANT4 receiving the first 5G radio frequency signal, and at least one of the four first antennas transmitting the first 5G radio frequency signal, the four second antennas ANT5, ANT6, ANT7, ANT8 receiving the second 5G radio frequency signal, and at least one of the four second antennas transmitting the second 5G radio frequency signal.

In some embodiments, referring to fig. 6, fig. 6 is a schematic diagram illustrating third signal transmission in the rf circuit provided in the embodiments of the present application.

Wherein, since the data amount transmitted by the first 5G radio frequency signal is greater than the data amount transmitted by the second 5G radio frequency signal, when the first 5G radio frequency signal includes communication service data, the second 5G radio frequency signal may also not include communication service data.

When the second 5G radio frequency signal does not include traffic data, the four second antennas ANT5, ANT6, ANT7, ANT8 are used to transmit the second 5G radio frequency signal at least one timing per the transmission period, and interrupt transmission of the second 5G radio frequency signal at least another timing per the transmission period. That is, the four second antennas ANT5, ANT6, ANT7, ANT8 are used to intermittently transmit the second 5G radio frequency signal in each of the transmission periods. Here, interrupt transmission may be understood as no transmission.

For example, the four second antennas ANT5, ANT6, ANT7, ANT8 may be used for transmitting the second 5G radio frequency signal at a timing of T2, T4 of each transmission period, and for interrupting transmission of the second 5G radio frequency signal at a timing of T1, T3 of each transmission period.

It can be understood that, when the second 5G radio frequency signal does not include communication service data, the data amount required to be transmitted by the second 5G radio frequency signal is small, and therefore, when the four second antennas ANT5, ANT6, ANT7 and ANT8 intermittently transmit the second 5G radio frequency signal, the data transmission requirement of the second 5G radio frequency signal can be met, the power consumption of the electronic device 100 can be effectively reduced, and the power consumption of the electronic device 100 is saved.

It should be noted that the four second antennas ANT5, ANT6, ANT7, ANT8 may also be used to transmit the second 5G radio frequency signal at different timings in each transmission period. For example, the second antennas ANT5, ANT6 may transmit the second 5G radio frequency signal at a timing of T2, T4 of each transmission period, and interrupt transmission of the second 5G radio frequency signal at a timing of T1, T3 of each transmission period; the second antennas ANT7, ANT8 may transmit the second 5G rf signal at a timing of T1, T3 every transmission period, and interrupt transmission of the second 5G rf signal at a timing of T2, T4 every transmission period.

Thus, it may be realized that one of the first SIM card 107 and the second SIM card 108 in the electronic device 100 is in a communication state and the other is in a standby state by the four first antennas ANT1, ANT2, ANT3 and ANT4 continuously transmitting the first 5G radio frequency signal and the four second antennas ANT5, ANT6, ANT7 and ANT8 intermittently transmitting the second 5G radio frequency signal.

It can be understood that, when the second 5G radio frequency signal does not include communication service data, only the 5G radio frequency signal may be received, for example, a call signal of another user is received from a base station, heartbeat packet data issued by the base station at regular or irregular time is received, and the like.

Accordingly, the four second antennas ANT5, ANT6, ANT7, ANT8 may be used to receive the second 5G radio frequency signal at least one timing of each of the transmission periods and to interrupt the reception of the second 5G radio frequency signal at least another timing of each of the transmission periods. For example, the four second antennas ANT5, ANT6, ANT7, ANT8 may be configured to receive the second 5G rf signal at a timing T2, T4 of each transmission period, and to interrupt receiving the second 5G rf signal at a timing T1, T3 of each transmission period. Wherein the reception of the interrupt may be understood as not receiving.

In some embodiments, referring to fig. 7, fig. 7 is a schematic diagram illustrating a fourth signal transmission in the rf circuit 200 according to an embodiment of the present disclosure.

Wherein, when neither the first 5G radio frequency signal nor the second 5G radio frequency signal includes communication traffic data, the four first antennas ANT1, ANT2, ANT3, ANT4 are used to transmit the first 5G radio frequency signal at least one timing of each transmission period, and to interrupt transmission of the first 5G radio frequency signal at least another timing of each transmission period; the four second antennas ANT5, ANT6, ANT7, ANT8 are configured to transmit the second 5G radio frequency signal at least one timing of each of the transmission periods and interrupt transmission of the second 5G radio frequency signal at least another timing of each of the transmission periods. That is, the four first antennas ANT1, ANT2, ANT3, ANT4 are used to intermittently transmit the first 5G rf signal in each transmission period, and the four second antennas ANT5, ANT6, ANT7, ANT8 are used to intermittently transmit the second 5G rf signal in each transmission period.

For example, the four first antennas ANT1, ANT2, ANT3, ANT4 may be used for transmitting the first 5G radio frequency signal at a T1, T3 timing of each transmission period, and for interrupting transmission of the first 5G radio frequency signal at a T2, T4 timing of each transmission period; the four second antennas ANT5, ANT6, ANT7, ANT8 may be configured to transmit the second 5G rf signal at a timing of T2, T4 of each of the transmission periods, and to interrupt transmission of the second 5G rf signal at a timing of T1, T3 of each of the transmission periods.

It can be understood that, when the first 5G radio frequency signal does not include communication service data, the data amount required to be transmitted by the first 5G radio frequency signal is small, and therefore, when the four first antennas ANT1, ANT2, ANT3 and ANT4 intermittently transmit the first 5G radio frequency signal, the data transmission requirement of the first 5G radio frequency signal can be met, the power consumption of the electronic device 100 can be effectively reduced, and the power consumption of the electronic device 100 is saved. Similarly, when the four second antennas ANT5, ANT6, ANT7, ANT8 intermittently transmit the second 5G radio frequency signal, the data transmission requirement of the second 5G radio frequency signal can be met, the power consumption of the electronic device 100 can be effectively reduced, and the power consumption of the electronic device 100 can be saved.

It should be noted that the four first antennas ANT1, ANT2, ANT3, ANT4 may also be configured to transmit the first 5G radio frequency signal at different timings in each transmission period. For example, the first antennas ANT1 and ANT2 may be configured to transmit the first 5G rf signal at a timing of T1 and T3 of each transmission period, and to interrupt transmission of the first 5G rf signal at a timing of T2 and T4 of each transmission period; the first antennas ANT3 and ANT4 may be configured to transmit the first 5G rf signal at a timing of T2 and T4 of each transmission period, and to interrupt transmission of the first 5G rf signal at a timing of T1 and T3 of each transmission period.

Likewise, the four second antennas ANT5, ANT6, ANT7, ANT8 may be used to transmit the second 5G radio frequency signal at different timings of each transmission period. For example, the second antennas ANT5, ANT6 may transmit the second 5G radio frequency signal at a timing of T2, T4 of each transmission period, and interrupt transmission of the second 5G radio frequency signal at a timing of T1, T3 of each transmission period; the second antennas ANT7, ANT8 may transmit the second 5G rf signal at a timing of T1, T3 every transmission period, and interrupt transmission of the second 5G rf signal at a timing of T2, T4 every transmission period.

Thus, the first 5G rf signal is intermittently transmitted through the four first antennas ANT1, ANT2, ANT3, ANT4, and the second 5G rf signal is intermittently transmitted through the four second antennas ANT5, ANT6, ANT7, ANT8, so that dual-card dual-standby of the first SIM card 107 and the second SIM card 108 in the electronic device 100 can be realized.

It can be understood that, when the first 5G radio frequency signal does not include communication service data, only the 5G radio frequency signal may be received, for example, a call signal of another user is received from a base station, heartbeat packet data issued by the base station at regular or irregular time is received, and the like.

Accordingly, the four first antennas ANT1, ANT2, ANT3, ANT4 may be used to receive the first 5G radio frequency signal at least one timing of each of the transmission periods and interrupt the reception of the first 5G radio frequency signal at least another timing of each of the transmission periods. For example, the four first antennas ANT1, ANT2, ANT3, ANT4 may be configured to receive the first 5G radio frequency signal at a timing of T1, T3 of each transmission period, and to interrupt receiving the first 5G radio frequency signal at a timing of T2, T4 of each transmission period.

Similarly, when the second 5G radio frequency signal does not include communication service data, only the 5G radio frequency signal may be received. Accordingly, the four second antennas ANT5, ANT6, ANT7, ANT8 may be used to receive the second 5G radio frequency signal at least one timing of each of the transmission periods and to interrupt the reception of the second 5G radio frequency signal at least another timing of each of the transmission periods. For example, the four second antennas ANT5, ANT6, ANT7, ANT8 may be configured to receive the second 5G rf signal at a timing T2, T4 of each transmission period, and to interrupt receiving the second 5G rf signal at a timing T1, T3 of each transmission period.
