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 diagram of a first structure 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, four first antennas 203, and a second antenna 204.
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.
Of the four first antennas 203, each of the first antennas 203 is connected with the modem 202. The second antenna 204 is also connected to the modem 202.
It should be noted that the radio frequency circuit 200 of the embodiment of the present application includes at least four first antennas 203, for example, four first antennas 203 shown in fig. 3. In addition, the number of the first antennas 203 included in the rf circuit 200 may also be greater than four, for example, five, six, and so on.
Similarly, the rf circuit 200 of the embodiment of the present application includes at least one second antenna 204, for example, one second antenna 204 shown in fig. 3. In addition, the number of the second antennas 204 included in the rf circuit 200 may also be more than one, such as two, three, and so on.
The four first antennas 203 and the four second antennas 204 may be used to transmit 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. 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.
When neither the first 5G radio frequency signal nor the second 5G radio frequency signal includes communication service data, the four first antennas 203 are used for transmitting the first 5G radio frequency signal and the second 5G radio frequency signal. At this time, the second antenna 204 may not transmit the 5G radio frequency signal, that is, the second antenna 204 may be idle.
When one of the first 5G radio frequency signal and the second 5G radio frequency signal includes communication service data and the other does not include communication service data, the four first antennas 203 are used for transmitting the 5G radio frequency signal including communication service data, and the second antenna 204 is used for transmitting the 5G radio frequency signal not including communication service data.
For example, if the first 5G radio frequency signal includes communication service data and the second 5G radio frequency signal does not include communication service data, the four first antennas 203 may be used to transmit the first 5G radio frequency signal, and the second antenna 204 may be used to transmit the second 5G radio frequency signal.
For another example, if the second 5G radio frequency signal includes communication service data and the first 5G radio frequency signal does not include communication service data, the four first antennas 203 may be used to transmit the second 5G radio frequency signal, and the second antenna 204 may be used to transmit the first 5G radio frequency signal.
When the first 5G radio frequency signal and the second 5G radio frequency signal both include communication service data, two first antennas of the four first antennas 203 are used to transmit the first 5G radio frequency signal, and the other two first antennas of the four first antennas 203 are used to transmit the second 5G radio frequency signal. At this time, the second antenna 204 may not transmit the 5G radio frequency signal, that is, the second antenna 204 may be idle.
It should be noted that the communication service data refers to data transmitted by the radio frequency circuit 200 in a process of communication between a user and another user through a base station. For example, in the process of calling another user through the base station, in the process of making a voice call with another user through the base station, in the process of sending a short message to 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 the server through the base station, the data transmitted 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.
The radio frequency circuit 200 provided in the embodiment of the present application, through configuring the functions of the four first antennas 203 and the second antenna 204 in different scenarios, not only can satisfy the data transmission requirement of the electronic device 100 in a SIM card or two SIM card standby modes, but also can satisfy the data transmission requirement of the electronic device 100 in a SIM card or two SIM cards when performing communication services, both dual-card dual-standby can be realized through one set of radio frequency communication system, dual-card dual-pass can be realized, meanwhile, the number of antennas in the radio frequency circuit 200 can be avoided from being increased, thereby reducing the occupation of the antennas on the internal space of the electronic device 100, and improving the space utilization rate inside the electronic device 100.
In some embodiments, the four first antennas 203 transmit the 5G rf signals periodically with a certain transmission period when transmitting the 5G rf signals. The transmission cycle may include a plurality of timings, for example, the transmission cycle may include four timings.
When neither the first 5G radio frequency signal nor the second 5G radio frequency signal includes communication service data, the four first antennas 203 are used for transmitting the first 5G radio frequency signal in the first time period of each transmission cycle, and the four first antennas 203 are further used for transmitting the second 5G radio frequency signal in the second time period of each transmission cycle. That is, the four first antennas 203 respectively transmit the first 5G rf signal and the second 5G rf signal in a time division manner. In each of the transmission cycles, the first period includes at least one timing and the second period includes at least another timing.
For example, as shown in fig. 4, fig. 4 is a schematic diagram of a first signal transmission in the radio frequency circuit provided in the embodiment of the present application. The four first antennas 203 may be, for example, ANT1, ANT2, ANT3, and ANT4, the second antenna 204 may be, for example, ANT5, and each transmission cycle may include, for example, four timings, such as T1, T2, T3, and T4.
It should be noted that, in fig. 4 and the figures appearing below, the SIM1 shown in the figure represents the first 5G rf signal of the first SIM card 107, and the SIM2 represents the second 5G rf signal of the second SIM card 108.
The four first antennas ANT1, ANT2, ANT3 and ANT4 may transmit the first 5G rf signal at T1 and T3 timings of each transmission period, and transmit the second 5G rf signal at T2 and T4 timings of each transmission period, where the second antenna ANT5 is idle. At this time, the first period includes timings T1, T3, and the second period includes timings T2, T4.
It should be noted that the first time period may be a continuous time period, or may be a discontinuous time period, that is, a time period with a discontinuity in the middle. Similarly, the second time period may also be a continuous time period, or may also be a discontinuous time period, that is, a time period with an interruption in the middle.
For another example, as shown in fig. 5, fig. 5 is a schematic diagram of a second signal transmission in the radio frequency circuit provided in the embodiment of the present application. The four first antennas ANT1, ANT2, ANT3 and ANT4 may transmit the first 5G rf signal at T1 and T2 timings of each transmission period, and transmit the second 5G rf signal at T3 and T4 timings of each transmission period, where the second antenna ANT5 is idle. At this time, the first period includes timings T1, T2, and the second period includes timings T3, T4.
Referring to fig. 6, fig. 6 is a schematic diagram illustrating third signal transmission in the rf circuit according to the embodiment of the present disclosure. The four first antennas ANT1, ANT2, ANT3, ANT4 may be configured to receive only 5G radio frequency signals in each transmission period, for example, receive a heartbeat packet sent by a base station, receive calls of other users through the base station, and the like. While the second antenna ANT5 may remain empty.
At this time, the four first antennas ANT1, ANT2, ANT3, ANT4 are to receive the first 5G radio frequency signal in a first period of each transmission period and to receive the second 5G radio frequency signal in a second period of each transmission period.
For example, the four first antennas ANT1, ANT2, ANT3, ANT4 may receive the first 5G radio frequency signal at a timing of T1, T2 of each transmission period, and receive the second 5G radio frequency signal at a timing of T3, T4 of each transmission period. At this time, the first period includes timings T1, T2, and the second period includes timings T3, T4.
Therefore, the electronic device 100 may implement dual-card dual standby of the first SIM card 107 and the second SIM card 108 by receiving the first 5G radio frequency signal and the second 5G radio frequency signal through the four first antennas ANT1, ANT2, ANT3 and ANT4 in a time-sharing manner.
In some embodiments, when one of the first 5G radio frequency signal and the second 5G radio frequency signal includes communication traffic data and the other does not include communication traffic data, the four first antennas ANT1, ANT2, ANT3, ANT4 are configured to receive the 5G radio frequency signal including communication traffic data, and at least one of the four first antennas is further configured to transmit the 5G radio frequency signal including communication traffic data, and the second antenna ANT5 is configured to receive the 5G radio frequency signal not including communication traffic data.
For example, as shown in fig. 7, fig. 7 is a schematic diagram of a fourth signal transmission in the radio frequency circuit provided in the embodiment of the present application. Wherein, when the first 5G radio frequency signal includes communication traffic data and the second 5G radio frequency signal does not include communication traffic data, the four first antennas ANT1, ANT2, ANT3, ANT4 are used to transmit the first 5G radio frequency signal, and the second antenna ANT5 is used to transmit the second 5G radio frequency signal.
As shown in fig. 7, the second antenna ANT5 may continuously transmit the second 5G rf signal in each transmission period, that is, transmit the second 5G rf signal at each timing in each transmission period, for example, transmit the second 5G rf signal at each timing of T1, T2, T3, and T4.
It is understood that the second antenna ANT5 may also discontinuously transmit the second 5G rf signal in each transmission period, that is, the transmission of the second 5G rf signal is interrupted in a part of the timing sequence in each transmission period. Here, interrupt transmission may be understood as no transmission.
Wherein the second antenna ANT5 may be configured to transmit the second 5G rf signal during a third time period of each transmission cycle and to interrupt transmission of the second 5G rf signal during a fourth time period of each transmission cycle. In each of the transmission cycles, the third time period includes at least one timing and the fourth time period includes at least another timing.
For example, as shown in fig. 8, fig. 8 is a schematic diagram of fifth signal transmission in the radio frequency circuit provided in the embodiment of the present application. Wherein the second antenna ANT5 may be configured to transmit the second 5G rf signal at a timing T2, T4 of each transmission period, and to interrupt transmission of the second 5G rf signal at a timing T1, T3 of each transmission period. At this time, the third period includes T2, T4 timing, and the fourth period includes T1, T3 timing.
It should be noted that the third time period may be a continuous time period, or may be a discontinuous time period, that is, a time period with a discontinuity in the middle. Similarly, the fourth time period may also be a continuous time period, or may also be a discontinuous time period, that is, a time period with an interruption in the middle.
It is understood that the second antenna ANT5 may also transmit the second 5G rf signal at the timing T1, T2 of each transmission period, and interrupt the transmission of the second 5G rf signal at the timing T3, T4 of each transmission period. At this time, the third period includes T1, T2 timing, and the fourth period includes T3, T4 timing.
Referring to fig. 9, fig. 9 is a schematic diagram illustrating sixth signal transmission in the rf circuit according to the embodiment of the present application. The four first antennas ANT1, ANT2, ANT3, and ANT4 may be configured to receive the first 5G radio frequency signal, for example, receive data transmitted by a base station; and at least one of the four first antennas ANT1, ANT2, ANT3, ANT4 is also used to transmit the first 5G radio frequency signal, for example, to transmit communication data of a user to a base station. For example, the first antenna ANT1 may be used to transmit the first 5G radio frequency signal at the same time. It is understood that more than one first antenna for transmitting the first 5G radio frequency signal may be provided, for example, the first antennas ANT1, ANT2 may be both for transmitting the first 5G radio frequency signal.
In addition, the second antenna ANT5 may be configured to receive only the second 5G radio frequency signal, for example, receive a heartbeat packet sent by a base station, receive calls of other users through the base station, and the like.
It is understood that, when the second antenna ANT5 discontinuously receives the second 5G rf signal, the second antenna ANT5 may be configured to receive the second 5G rf signal in a third time period of each transmission cycle and to interrupt receiving the second 5G rf signal in a fourth time period of each transmission cycle. Wherein the reception of the interrupt may be understood as not receiving.
It is understood that, when the second 5G radio frequency signal includes communication traffic data and the first 5G radio frequency signal does not include communication traffic data, the transmission configurations of the four first antennas ANT1, ANT2, ANT3, ANT4 and the second antenna ANT5 for the first 5G radio frequency signal and the second 5G radio frequency signal may be reversed.
For example, the four first antennas ANT1, ANT2, ANT3, ANT4 may be used to receive the second 5G radio frequency signal, and at least one of the four first antennas ANT1, ANT2, ANT3, ANT4 is also used to transmit the second 5G radio frequency signal. For example, the first antenna ANT1 may be used to transmit the second 5G radio frequency signal at the same time.
In addition, the second antenna ANT5 may be used to receive the first 5G radio frequency signal.
It is understood that, when the second antenna ANT5 discontinuously receives the first 5G rf signal, the second antenna ANT5 may be configured to receive the first 5G rf signal in a third time period of each transmission cycle and to interrupt receiving the first 5G rf signal in a fourth time period of each transmission cycle.
Thus, the electronic device 100 may implement that one of the first SIM card 107 and the second SIM card 108 maintains a communication state and the other maintains a standby state by transmitting a 5G radio frequency signal including communication service data through the four first antennas ANT1, ANT2, ANT3, ANT4 and transmitting a 5G radio frequency signal not including communication service data through the second antenna ANT 5.
In some embodiments, when the first 5G radio frequency signal and the second 5G radio frequency signal both include communication traffic data, two first antennas of the four first antennas ANT1, ANT2, ANT3, ANT4 are used for receiving the first 5G radio frequency signal, and at least one of the two first antennas is also used for transmitting the first 5G radio frequency signal.
Furthermore, two other first antennas of the four first antennas ANT1, ANT2, ANT3, ANT4 are used for receiving the second 5G radio frequency signal, and at least one of the two other first antennas is also used for transmitting the second 5G radio frequency signal.
At this time, the second antenna ANT5 may remain empty.

It is understood that more than one first antenna for transmitting the first 5G radio frequency signal may be provided, for example, the first antennas ANT1, ANT2 may be both for transmitting the first 5G radio frequency signal.
Furthermore, the first antennas ANT1, ANT2 may be used to receive the first 5G radio frequency signal, and the first antenna ANT1 may also be used to transmit the first 5G radio frequency signal. It is understood that more than one first antenna for transmitting the first 5G radio frequency signal may be provided, for example, the first antennas ANT1, ANT2 may be both for transmitting the first 5G radio frequency signal.

Other configuration scenarios are not described in detail.
Thus, the electronic device 100 may implement dual-card dual-pass of the first SIM card 107 and the second SIM card 108 by two of the four first antennas ANT1, ANT2, ANT3 and ANT4 transmitting a first 5G radio frequency signal and the other two of the four first antennas ANT1, ANT2, ANT3 and ANT4 transmitting a second 5G radio frequency signal.

The rf front-end module 205 is configured to switch the 5G rf signals transmitted by each of the first antenna 203 and the second antenna 204.
For example, when neither the first 5G rf signal nor the second 5G rf signal includes communication service data, the rf front-end module 205 may switch to the four first antennas 203 to transmit the first 5G rf signal and the second 5G rf signal in a time-sharing manner, and the second antenna 204 is idle.
