The rf circuit 200 is used to enable wireless communication between the electronic device 100 and a base station or other electronic devices. It is understood that the rf circuit 200 may be used to transmit both 4G network signals and 5G network signals.

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, a 5G signal stream and a 4G signal stream need to be transmitted simultaneously. That is, in the 5G network architecture of NSA, 5G network signals include 4G signal streams and 5G signal streams.

The radio frequency circuit 200 according to the embodiment of the present application may be used to transmit a non-independent networking 5G network signal and to transmit a 4G network signal. For example, the rf circuit 200 may be used to transmit 5G network signals of the NSA network architecture of the first SIM card 107, and may also be used to transmit 4G network signals of the second SIM card 108. It is understood that the 5G network signal of the first SIM card 107 refers to a network signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices by the fifth generation mobile communication technology through the information stored in the first SIM card 107, and the 4G network signal of the second SIM card 108 refers to a network signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices by the fourth generation mobile communication technology through the information stored in the second SIM card 108.

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 first modem 202, a second modem 203, at least two first splitters 204, at least two first antennas 205 and at least two second antennas 206.

It should be noted that, although fig. 3 shows the rf circuit 200 including two first splitters 204, two first antennas 205, and two second antennas 206, the application is not limited thereto. The rf circuit 200 may also comprise other numbers of first splitters 204, first antennas 205 and second antennas 206, for example 3, 4, etc.

The baseband circuit 201 is configured to process communication data of the radio frequency circuit 200, and control an operating state of each device in the radio frequency circuit 200 according to interaction information with a base station or a 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 is understood that the rf circuit 200 may be used to transmit the non-independently networked 5G network signals of the first SIM card and the 4G network signals of the second SIM card. Wherein the 5G network signal comprises a 4G signal stream and a 5G signal stream. The 4G signal flow, the 5G signal flow and the 4G network signal all carry information. Wherein, the carried information refers to that the 4G signal stream, the 5G signal stream, and the 4G network signal are not null signals, but signals carrying communication contents of a user. The baseband circuit 201 may be configured to process the 4G signal stream, the 5G signal stream, and the 4G network signal.

The first modem 202 is connected to the baseband circuit 201. The first modem 202 is used for processing 4G radio frequency signals. For example, the first modem 202 may modulate 4G upstream signals passing through the first modem 202 and demodulate 4G downstream signals passing through the first modem 202.

A second modem 203 is connected to the baseband circuitry 201. The second modem 203 is used for processing the 5G radio frequency signal. For example, the second modem 203 may modulate 5G upstream signals passing through the second modem 203 and demodulate 5G downstream signals passing through the second modem 203.

It can be understood that, when the radio frequency circuit 200 transmits 5G network signals of the NSA network architecture of the first SIM card and 4G network signals of the second SIM card, since the 5G network signals include 4G signal streams and 5G signal streams, the first modem 202 may be configured to process the 4G signal streams of the first SIM card and the 4G network signals of the second SIM card, and the second modem 203 may be configured to process the 5G signal streams of the first SIM card.

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.

At least two first splitters 204, each first splitter 204 is connected to the first modem 202 and the second modem 203 simultaneously. The first splitter 204 is configured to combine and split the radio frequency signal. That is, the first splitter 204 may be configured to combine two uplink signals into one uplink signal, and to split one downlink signal into two downlink signals.

The first splitter 204 may be a frequency divider, a multiplexer, or the like. The multiplexer may include a duplexer, a quadplexer, a hexaplexer, and the like.

It will be appreciated that the first splitter 204 may also be replaced by a high frequency switch. For example, the first splitter 204 may be replaced by a Thin Film Transistor (TFT), through which the first splitter 204 is switched between turning on the first modem 202 and turning on the second modem 203.

At least two first antennas 205, each first antenna 205 being connected to the first modem 202 and the second modem 203. The at least two first antennas 205 are configured to receive a 4G signal stream of the first SIM card, a 5G signal stream of the first SIM card, and a 4G network signal of the second SIM card in each receiving period.

The receiving period may be understood as a receiving period of the rf circuit 200. The reception period may be, for example, 10ms (milliseconds).

It is to be understood that each of the first splitters 204 can be simultaneously connected to the first modem 202, the second modem 203 and one of the first antennas 205, so as to connect each of the first antennas 205 to the first modem 202 and the second modem 203.

At least two second antennas 206, each second antenna 206 being connected to the second modem 203. The at least two second antennas 206 are configured to receive a 5G signal stream in the 5G network signal of the first SIM card in each of the receiving periods.

In the rf circuit 200, the process of receiving signals is as follows:

after receiving the rf signal from the outside, the first antenna 205 transmits the received rf signal to the first splitter 204 connected to the first antenna 205 for splitting. Subsequently, the split 4G signal stream in the 5G network signal of the first SIM card and the split 4G network signal of the second SIM card are transmitted to the first modem 202 for demodulation, and the split 5G signal stream in the 5G network signal of the first SIM card is transmitted to the second modem 203 for demodulation.

The second antenna 206 receives the 5G signal stream from the outside, and transmits the received 5G signal stream to the second modem 203 for demodulation.

After receiving the 4G signal stream and the 4G network signal, the first modem 202 demodulates the 4G signal stream and the 4G network signal, and transmits the demodulated radio frequency signal to the baseband circuit 201 for processing.

After receiving the 5G signal stream, the second modem 203 demodulates the 5G signal stream, and transmits the demodulated radio frequency signal to the baseband circuit 201 for processing.

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 achieve 2-way reception, while a complete 5G network communication link requires at least 4 antennas to achieve 4-way reception. Thus, for an electronic device including two SIM cards, the radio frequency circuit needs to be provided with at least 6 antennas to simultaneously receive the 5G network signal of one SIM card and the 4G network signal of the other SIM card.

The radio frequency circuit 200 provided in the embodiment of the present application can implement two-way reception of a 4G signal stream in a 5G network signal of an NSA mode of the first SIM card, can implement 4-way reception of a 5G signal stream in a 5G network signal of the first SIM card, and can implement two-way reception of a 4G network signal of the second SIM card. Therefore, the at least two first antennas 205 can be shared when receiving the radio frequency signal of the first SIM card and the radio frequency signal of the second SIM card, and multiple independent antennas are not required to be arranged for receiving the radio frequency signal of the first SIM card and multiple independent antennas are not required to be arranged for receiving the radio frequency signal of the second SIM card, so that the number of antennas of the radio frequency circuit 200 can be reduced, and the space utilization rate inside the electronic device can be improved.

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.

Wherein the communication frequency of the 4G signal stream in the 5G network signal of the first SIM card is different from the communication frequency of the 4G network signal of the second SIM card. The communication frequency of the 4G signal stream is different from the communication frequency of the 4G network signal, which includes two cases.

In the first case, the frequency band of the communication frequency of the 4G signal stream is different from the frequency band of the communication frequency of the 4G network signal. For example, the communication frequency of the 4G signal stream is in a Band1 frequency Band (downlink frequency 2110MHz-2170MHz), and the communication frequency of the 4G network signal is in a Band3 frequency Band (downlink frequency 1805MHz-1880 MHz). When the 4G signal stream and the 4G network signal are in different frequency bands, the communication frequencies are naturally different.

In the second case, the frequency band of the communication frequency of the 4G signal stream is the same as the frequency band of the communication frequency of the 4G network signal, but the frequency points of the two are different. For example, the communication frequency of the 4G signal stream and the communication frequency of the 4G network signal are both in a Band1 frequency Band, where the frequency point of the 4G signal stream is 2120MHz (megahertz), and the frequency point of the 4G network signal is 2150 MHz. At this time, the communication frequency of the 4G signal stream is also different from the communication frequency of the 4G network signal.

Wherein the at least two first antennas 205 may include antennas ANT1, ANT2, and the at least two second antennas 206 may include antennas ANT3, ANT 4.

The at least two first antennas 205 are configured to simultaneously receive a 4G signal stream of the 5G network signals of the first SIM card and a 4G network signal of the second SIM card in each of the receiving periods. In addition, the at least two first antennas 205 are further configured to receive a 5G signal stream in the 5G network signal of the first SIM card in each of the receiving periods.

The at least two second antennas 206 are configured to receive a 5G signal stream in the 5G network signal of the first SIM card in each of the receiving periods.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a second signal transmission in the rf circuit 200 according to the embodiment of the present disclosure.

Wherein, the communication frequency of the 4G signal stream in the 5G network signal of the first SIM card is equal to the communication frequency of the 4G network signal of the second SIM card. That is, the frequency band of the communication frequency of the 4G signal stream is the same as the frequency band of the communication frequency of the 4G network signal, and the frequency points of the two are also the same.

For example, the communication frequency of the 4G signal stream and the communication frequency of the 4G network signal are both in a Band1 frequency Band, and the frequency points of both are 2120 MHz.

The at least two first antennas 205 are configured to receive a 4G signal stream of the 5G network signals of the first SIM card for a first time period in each of the receiving periods, and to receive a 4G network signal of the second SIM card for a second time period in each of the receiving periods. Wherein the first time period and the second time period are different time periods in each receiving cycle. For example, the first time period is the first one-third period in each of the receiving periods, and the second time period is the last two-thirds period in each of the receiving periods.

In addition, the at least two first antennas 205 are further configured to receive a 5G signal stream in the 5G network signal of the first SIM card in each of the receiving periods.

It is to be understood that the first time period may be a first half period in each of the receiving periods, and the second time period may be a second half period in each of the receiving periods. Thus, the at least two first antennas 205 may receive the 4G signal stream for half of the duration of each receive period and the 4G network signal for the other half of the duration of each receive period.

It is understood that the first modem 202 may include a first processing channel and a second processing channel. The first processing channel is used for processing the 4G signal stream, and the second processing channel is used for processing the 4G network signal.

Wherein, in the first time period, the first processing channel is opened, and the second processing channel is closed, so that a 4G signal stream in the 5G network signals of the first SIM card can be received through the at least two first antennas 205.

During the second time period, the first processing channel is closed, and the second processing channel is opened, so that the 4G network signal of the second SIM card can be received through the at least two first antennas 205.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a second structure of the rf circuit 200 according to the embodiment of the present disclosure.

The rf circuit 200 further includes a control circuit 207. The control circuit 207 is connected to the first modem 202.

The control circuit 207 is configured to: controlling a first processing channel of the first modem 202 to be open and a second processing channel of the first modem 202 to be closed during the first time period; during the second time period, the first processing channel of the first modem 202 is controlled to be closed, and the second processing channel of the first modem 202 is controlled to be opened.

Thus, the control circuit 207 may control the first modem 202 to enable the at least two first antennas 205 to receive the 4G network signals of the second SIM card and the 4G signal stream of the first SIM card respectively at different time periods in each receiving period.

It is understood that the control circuit 207 may also be integrated in the baseband circuit 201, for example, the control circuit 207 and the baseband circuit 201 may be integrated as a baseband circuit chip. Furthermore, the control circuit 207 may also be integrated in a processor of the electronic device 100.

Referring to fig. 7, fig. 7 is a schematic diagram illustrating a third structure of the rf circuit 200 according to the embodiment of the present disclosure.

Wherein the at least two second antennas 206 are further connected to the first modem 202. The at least two second antennas 206 are further configured to receive a 4G signal stream in the 5G network signals of the first SIM card or receive 4G network signals of the second SIM card in each of the receiving periods.

After the at least two second antennas 206 receive the 4G signal stream in the 5G network signal of the first SIM card or receive the 4G network signal of the second SIM card, transmit the received 4G signal stream or 4G network signal to the first modem 202 for demodulation. The first modem 202 then transmits the demodulated rf signal to the baseband circuit 201 for processing.

Thus, the at least two second antennas 206 and the at least two first antennas 205 may jointly implement 4-way reception of the 4G signal stream or implement 4-way reception of the 4G network signal, so as to improve the stability of the received 4G signal stream or improve the stability of the received 4G network signal.

Therein, it is understood that the rf circuit 200 may further include at least two second splitters 208.

Each of the second splitters 208 is connected to the first modem 202, the second modem 203 and one of the second antennas 206, so that each of the second antennas 206 is simultaneously connected to the first modem 202 and the second modem 203.

The second splitter 208 may be a frequency divider, a multiplexer, or the like. The multiplexer may include a duplexer, a quadplexer, a hexaplexer, and the like.

Referring to fig. 8, fig. 8 is a schematic diagram illustrating a fourth structure of the rf circuit 200 according to the embodiment of the present disclosure.

The rf circuit 200 further includes a first rf transceiver module 209 and a second rf transceiver module 210.

The first rf transceiver module 209 is connected to the first modem 202 and the at least two first antennas 205. The first rf transceiver module 209 is configured to receive, through the at least two first antennas 205, a 4G signal stream in the 5G network signals of the first SIM card and a 4G network signal of the second SIM card.

In addition, the first rf transceiver module 209 may also be connected to the at least two second antennas 206. The first radio frequency transceiver module 209 may further receive, through the at least two second antennas 206, a 4G signal stream in the 5G network signals of the first SIM card and a 4G network signal of the second SIM card.

It is understood that the first rf transceiver module 209 may be connected to each of the first antennas 205 through the first splitter 204, and connected to each of the second antennas 206 through the second splitter 208.

The first rf transceiver module 209 may be provided with a plurality of rf receiving ports. Each radio frequency receiving port is connected with an antenna. Each radio frequency receiving port is used for acquiring a 4G signal stream of the first SIM card or a 4G network signal of the second SIM card received by the antenna connected with the radio frequency receiving port from the outside.

The second rf transceiver module 210 is connected to the second modem 203, the at least two first antennas 205, and the at least two second antennas 206.
