Referring to FIG. 3 , FIG. 3 is a schematic diagram of a first structure of a radio frequency circuit 200 provided by an embodiment of the present application.

The radio frequency circuit 200 includes 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 the radio frequency circuit 200 shown in FIG. 3 includes two first splitters 204 , two first antennas 205 , and two second antennas 206 , this application is not limited thereto. The number of the first splitter 204, the first antenna 205, and the second antenna 206 included in the radio frequency circuit 200 may also be other numbers, such as three, four, and so on.

The baseband circuit 201 is used to process the communication data of the radio frequency circuit 200, and control the working state of each device in the radio frequency circuit 200 according to the interactive information with the base station or the network server. It can be understood that the baseband circuit 201 may be integrated into the processor of the electronic device 100, or may be an independent processing circuit or a processing chip.

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 the upstream signal passing through the first modem 202 and demodulate the downstream signal passing through the first modem 202 .

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

It can be understood that when the radio frequency circuit 200 transmits the 5G network signal of the NSA network architecture, since the 5G network signal includes a 4G signal flow and a 5G signal flow, the first modem 202 can be used for the 4G signal flow at this time. The signal stream is processed, and the second modem 203 can be used to process the 5G signal stream.

It can be understood that the uplink signal refers to the radio frequency signal that the radio frequency circuit 200 transmits to the outside through the antenna, and the downlink signal refers to the radio frequency signal that the radio frequency circuit 200 receives from the outside world through the antenna.

Among the at least two first splitters 204 , each of the first splitters 204 is connected to the first modem 202 and the second modem 203 at the same time. The first splitter 204 is used for combining and splitting the radio frequency signals. That is, the first splitter 204 can be used for combining two uplink signals into one uplink signal, and for splitting one downlink signal into two downlink signals.

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

It can be understood that the first splitter 204 can also be replaced by a high frequency switch. For example, the first splitter 204 can be replaced by a thin film transistor (Thin Film Transistor, TFT), and the first splitter 204 can be switched between turning on the first modem 202 and turning on the second modem 203 through a TFT .

Among the at least two first antennas 205 , each of the first antennas 205 is connected to the first modem 202 and the second modem 203 . The at least two first antennas 205 are used to transmit the 4G signal stream of the 5G network signal and the 5G signal stream. The transmitting 4G signal stream and 5G signal stream includes: transmitting 4G signal stream, receiving 4G signal stream, transmitting and receiving 4G signal stream, transmitting 5G signal stream, receiving 5G signal stream, transmitting and receiving 5G signal stream. For example, among the at least two first antennas 205, one first antenna 205 may be used for transmitting and receiving 4G signal streams, and the other first antenna 205 may be used for receiving 5G signal streams. Alternatively, among the at least two first antennas 205, one first antenna 205 may be used for transmitting and receiving 4G signal streams, and the other first antenna 205 may be used for transmitting and receiving 5G signal streams.

Wherein, it can be understood that each of the first splitters 204 can be connected to the first modem 202, the second modem 203 and one of the first antennas 205 at the same time, so as to realize each of the first antennas 205 Both are connected to the first modem 202 and the second modem 203 .

It should be noted that, the 4G signal stream or the 5G signal stream transmitted by each of the first antennas 205 may carry information or not. Wherein, the signal flow carrying information can be understood as mixing the communication content of the user during the modulation process of the signal flow. A signal stream that does not carry information can be understood as an empty signal stream, that is, a signal stream in which the user's communication content is not mixed into the signal stream during the modulation process, or the signal stream is not modulated.

Wherein, when at least one of the first antennas 205 transmits a 4G signal stream carrying information, the at least one first antenna 205 simultaneously transmits an empty 5G signal stream. When at least one of the first antennas 205 transmits a 5G signal stream carrying information, the at least one first antenna 205 simultaneously transmits an empty 4G signal stream. That is, among the at least two first antennas 205, at least one transmitted signal stream carries information, while at least another transmitted signal stream does not carry information, and the signal stream that does not carry information is an empty signal stream. Therefore, when each of the first antennas 205 transmits the 4G signal stream and the 5G signal stream at the same time, it is possible to avoid mutual influence between the transmitted signal streams.

Each of the at least two second antennas 206 is connected to the second modem 203 . The at least two second antennas 206 are used to transmit the 5G signal stream of the 5G network signal. The transmitting 5G signal stream includes: transmitting a 5G signal stream, receiving a 5G signal stream, and transmitting and receiving a 5G signal stream. For example, among the at least two second antennas 206, one second antenna 206 may be used for transmitting and receiving 5G signal streams, and the other second antenna 206 may be used for receiving 5G signal streams. Wherein, each 5G signal stream transmitted by the second antenna 206 carries information, that is, a signal stream that is not empty.

In the radio frequency circuit 200, the transmission process of the uplink signal is as follows:

The baseband circuit 201 processes the 4G signal stream and the 5G signal stream of the 5G network signal of the first SIM card to be transmitted to the outside world, and then transmits the processed 4G signal stream to the first modem 202 for modulation, and converts the processed 4G signal stream to the first modem 202 for modulation. The 5G signal is streamed to the second modem 203 for modulation.

After the first modem 202 modulates the 4G signal stream, it transmits the modulated 4G signal stream to a first splitter 204 , and transmits the modulated 4G signal stream to a first splitter 204 via the first splitter 204 to communicate with the first splitter. 204 is connected to the first antenna 205, and the modulated 4G signal stream is transmitted to the outside world through the first antenna 205.

After the second modem 203 modulates the 5G signal stream, it transmits the modulated 5G signal stream to a second antenna 206 and transmits the modulated 5G signal stream to the outside through the second antenna 206 . Alternatively, after modulating the 5G signal stream, the second modem 203 transmits the modulated 5G signal stream to a first splitter 204, and transmits the modulated 5G signal stream to a first splitter 204 via the first splitter 204 to communicate with the first splitter The first antenna 205 connected to the router 204, and the modulated 5G signal stream is transmitted to the outside world through the first antenna 205.

In the radio frequency circuit 200, the transmission process of the downlink signal is as follows:

After the first antenna 205 receives the 4G signal stream and the 5G signal stream from the outside world, it transmits the received 4G signal stream and the 5G signal stream to the first splitter 204 connected to the first antenna 205 for splitting, and then The branched 4G signal stream is transmitted to the first modem 202 for demodulation, and the branched 5G signal stream is transmitted to the second modem 203 for demodulation.

After receiving the 5G signal stream from the outside world, the second antenna 206 transmits the received 5G signal stream to the second modem 203 for demodulation.

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

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

It is important to point out that we are currently in the construction and development stage of the 5G network. Compared with 4G network, 5G network is special.

According to 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 the communication link formed by at least 4 antennas of the 5G network, one antenna needs to be maintained to implement SRS (Sounding Reference Signal, uplink sounding reference signal) communication between the electronic device and the base station. The uplink sounding reference signal is also called a channel sounding reference signal. That is, in the 5G network communication link between the electronic device and the base station, it is necessary to maintain an antenna to send the SRS signal to the base station, and the base station evaluates the downlink channel quality between the base station and the electronic device through the received SRS signal, so as to facilitate Downlink channel resource allocation between base stations and electronic devices. 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 transmits the SRS signal to the base station in a time-division manner sequentially through each of the at least four antennas of the 5G network communication link. Wherein, the SRS signal does not carry the communication content of the communication between the user and other users, and is only used for the base station to evaluate the downlink channel quality.

In the above radio frequency circuit 200 , the SRS signal can be switched between the at least two first antennas 205 and the at least two second antennas 206 . That is, the SRS signal is sent to the base station in a time-division manner through one of the at least two first antennas 205 and the at least two second antennas 206 in sequence, the at least two first antennas 205 and the at least two second antennas 206 The other antennas of the at least two second antennas 206 enable transmission of the user's communication content between the electronic device and the base station.

In this application, when the radio frequency circuit 200 transmits 5G network signals of the NSA network architecture, at least two first antennas 205 of the radio frequency circuit 200 can transmit both 4G signal streams and 5G signal streams. In the first antenna 205, the signal stream transmitted by at least one antenna carries information, while the signal stream transmitted by at least another antenna does not carry information, so that the transmission of the 4G signal stream and the transmission of the 5G signal stream can realize the transmission of the at least two first antennas. 205 shared. Therefore, the radio frequency circuit 200 of the present application can not only realize the transmission of 5G network signals of the NSA network architecture, but also can reduce the number of antennas of the radio frequency circuit 200 and reduce the occupation of the internal space of the electronic device 100 by the antennas, thereby improving the space utilization inside the electronic device. Rate.

Referring to FIG. 4 at the same time, FIG. 4 is a schematic diagram of the first signal transmission in the radio frequency circuit 200 provided by the embodiment of the present application. Among the at least two shared first antennas 205, at least one is used for transmitting and receiving 4G signal streams and receiving 5G signal streams, and at least the other is used for receiving 4G signal streams and 5G signal streams.

Wherein, the at least two first antennas 205 include a first main antenna and a first diversity antenna. The first main antenna is used for transmitting and receiving the 4G signal flow and for receiving the 5G signal flow, so as to realize the main transmission and reception of the 4G signal flow and the diversity reception of the 5G signal flow. The first diversity antenna is used for receiving the 4G signal stream and for receiving the 5G signal stream, so as to realize the diversity reception of the 4G signal stream and the diversity reception of the 5G signal stream.

It should be noted that the first main set of antennas only needs one antenna to transmit and receive the 4G signal stream at the same time. The first diversity antenna may include multiple antennas, so as to implement MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) reception of the 4G signal stream and the 5G signal stream.

The at least two second antennas 206 include a second main antenna and a second diversity antenna. The second main antenna is used for transmitting and receiving the 5G signal flow, so as to realize the main transmission and reception of the 5G signal flow. The second diversity antenna is used for receiving the 5G signal stream, so as to realize diversity reception of the 5G signal stream.

It should be noted that, only one antenna is needed for the second main set of antennas to simultaneously transmit and receive the 5G signal stream. The second diversity antenna may include multiple antennas, thereby enabling MIMO reception of the 5G signal stream.

Therefore, the radio frequency circuit 200 can not only realize the main set of sending and receiving and the diversity receiving of the 4G signal flow in the 5G network signal of the first SIM card, but also can realize the 5G signal in the 5G network signal of the first SIM card. The main set of transmission and reception of streams and the diversity of MIMO reception, and the sharing of at least two first antennas 205 can be realized.

It can be understood that when the first main antenna is used for transmitting and receiving the 4G signal stream and for receiving the 5G signal stream, when the first main antenna transmits or receives the 4G signal carrying information When streaming, the first main set antenna also receives an empty 5G signal flow, so as to avoid mutual influence between the 4G signal flow transmitted or received by the first main set antenna and the received 5G signal flow. When the first diversity antenna is used for receiving the 4G signal stream and for receiving the 5G signal stream, the first diversity antenna receives the empty 4G signal stream and receives the 5G signal stream carrying information, so as to avoid the The 4G signal stream received by the first diversity antenna and the 5G signal stream received influence each other. In addition, through the cooperation between the first main antenna and the first diversity antenna, it is also possible to simultaneously transmit the 4G signal carrying information and the 5G signal flow carrying information, without causing communication interruption of the 4G signal flow, It will also not cause communication interruption of 5G signal flow.

When the first main antenna is used for transmitting and receiving the 4G signal stream and for receiving the 5G signal stream, when the first main antenna receives the 5G signal stream carrying information, the first main antenna The set antenna also transmits or receives an empty 4G signal stream to avoid mutual influence between the 5G signal stream received by the first main set antenna and the transmitted or received 4G signal stream. When the first diversity antenna is used for receiving the 4G signal stream and for receiving the 5G signal stream, the first diversity antenna receives the empty 5G signal stream and receives the 4G signal stream carrying information, so as to avoid the The 5G signal stream received by the first diversity antenna and the 4G signal stream received influence each other. In addition, through the cooperation between the first main antenna and the first diversity antenna, it is also possible to simultaneously transmit the 4G signal carrying information and the 5G signal flow carrying information, without causing communication interruption of the 4G signal flow, It will also not cause communication interruption of 5G signal flow.

In addition, it can be understood that the at least two first antennas 205 can also be used to transmit the 5G signal stream in the 5G network signal of the first SIM card. Referring to FIG. 5 , FIG. 5 is a schematic diagram of the second type of signal transmission in the radio frequency circuit 200 provided by the embodiment of the present application. Among the at least two shared first antennas 205, at least one is used for transmitting and receiving 4G signal streams and receiving 5G signal streams, and at least the other is used for transmitting and receiving 5G signal streams and receiving 4G signal streams.

Wherein, the at least two first antennas 205 include a third main set of antennas and a fourth main set of antennas. The third main antenna is used for transmitting and receiving the 4G signal flow and for receiving the 5G signal flow, so as to realize the main transmission and reception of the 4G signal flow and the diversity reception of the 5G signal flow. The fourth main antenna is used for transmitting and receiving the 5G signal flow and for receiving the 4G signal flow, so as to realize the main transmission and reception of the 5G signal flow and the diversity reception of the 4G signal flow.

It should be noted that the third main antenna only needs one antenna to transmit and receive the 4G signal stream at the same time, and the fourth main antenna also only needs one antenna to simultaneously transmit and receive the 5G signal stream.

The at least two second antennas 206 include a third diversity antenna. The third diversity antenna is used for receiving the 5G signal stream, so as to realize diversity reception of the 5G signal stream.

It should be noted that the third diversity antenna includes multiple antennas, so that MIMO reception of the 5G signal stream can be implemented.
