Theradio frequency circuit 200 is used to enable wireless communication between theelectronic device 100 and a base station or other electronic devices. It is understood that therf 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, it is necessary to transmit 5G signals and 4G signals at the same time. That is, in the 5G network architecture of NSA, 5G signals include 4G signal streams and 5G signal streams.
Theradio frequency circuit 200 according to the embodiment of the present application may be used to transmit a non-independent 5G network signal. For example, theradio frequency circuit 200 may be used to transmit 5G signals of the NSA network architecture of thefirst SIM card 107. It is understood that the 5G signal of thefirst SIM card 107 refers to a network signal when theelectronic device 100 wirelessly communicates with a base station or other electronic devices through the information stored in thefirst SIM card 107 in the fifth generation mobile communication technology.
Referring to fig. 3, fig. 3 is a schematic diagram of a first structure of aradio frequency circuit 200 according to an embodiment of the present disclosure.

Thebaseband processing module 201 is configured to process communication data of theradio frequency circuit 200, and control an operating state of each device in theradio frequency circuit 200 according to interaction information with a base station or a network server. It is understood that thebaseband processing module 201 may be integrated into the processor of theelectronic device 100, or may be independent of a separate processing circuit or processing chip.
Thefirst modem 202 is connected to thebaseband processing module 201, and is configured to process the 4G radio frequency signal. For example, thefirst modem 202 may modulate upstream signals passing through thefirst modem 202 and demodulate downstream signals passing through thefirst modem 202.

For example, thesecond modem 203 may modulate upstream signals passing through thesecond modem 203 and demodulate downstream signals passing through thesecond modem 203.
The uplink signal refers to a radio frequency signal transmitted by theradio frequency circuit 200 to the outside through an antenna, and the downlink signal refers to a radio frequency signal received by theradio frequency circuit 200 from the outside through the antenna.
It is to be understood that when therf circuit 200 transmits a 5G network signal of an NSA network architecture, since the 5G signal includes a 4G signal stream and a 5G signal stream, thefirst modem 202 may be configured to process the 4G signal stream, and thesecond modem 203 may be configured to process the 5G signal stream.
Eachsplitter 204 of the foursplitters 204 is connected to thefirst modem 202 and thesecond modem 203 at the same time, and is used for combining and splitting the radio frequency signals.

It should be noted that thesplitter 204 may also be replaced by a high frequency switch. For example, thesplitter 204 may be replaced by a Thin Film Transistor (TFT), through which thesplitter 204 is switched between turning on thefirst modem 202 and turning on thesecond modem 203.
Each of the fourantennas 205 is connected to thefirst modem 202 and thesecond modem 203 through asplitter 204, and is configured to transmit the 5G signal and the 4G signal of the first SIM card and receive the 4G signal of the second SIM card. The transmitting of the 5G signal and the 4G signal of the first SIM card comprises transmitting the 4G signal stream of the first SIM card, receiving the 4G signal stream of the first SIM card, transmitting and receiving the 4G signal stream of the first SIM card, transmitting the 5G signal stream of the first SIM card, receiving the 5G signal stream of the first SIM card, and transmitting and receiving the 5G signal stream of the first SIM card. It is understood that the 5G signal and the 4G signal of the first SIM card refer to network signals when theelectronic device 100 wirelessly communicates with a base station or other electronic devices through information stored in the first SIM card in fifth and fourth generation mobile communication technologies.
Thefirst antenna 2051 is simultaneously connected to thefirst modem 202 and thesecond modem 203 through thefirst splitter 2041, and is used for transmitting or receiving a 5G signal stream of the first SIM card in multiple periods. Specifically, thefirst antenna 2051 may be connected to one end of thefirst splitter 2041, and the other end of thefirst splitter 2041 is connected to thefirst modem 202 and thesecond modem 203 at the same time, so that thefirst antenna 2051 is connected to thefirst modem 202 and thesecond modem 203 at the same time.
Thesecond antenna 2052 is connected to thefirst modem 202 and thesecond modem 203 through thesecond splitter 2042, and is configured to receive a 5G signal stream of the first SIM card, transmit or receive a 4G signal stream of the first SIM card, and receive a 4G signal of the second SIM card in multiple periods. In particular, thesecond antenna 2052 may be connected to one end of thesecond splitter 2042, and the other end of thesecond splitter 2042 is connected to both thefirst modem 202 and thesecond modem 203, so as to enable thesecond antenna 2052 to be connected to both thefirst modem 202 and thesecond modem 203.
Thethird antenna 2053 is simultaneously connected to thefirst modem 202 and thesecond modem 203 through thethird splitter 2043, and is configured to receive a 5G signal stream of the first SIM card, transmit or receive a 4G signal stream of the first SIM card, and receive a 4G signal of the second SIM card in multiple periods. Specifically, thethird antenna 2053 may be connected to one end of thethird splitter 2043, and the other end of thethird splitter 2043 is connected to thefirst modem 202 and thesecond modem 203 at the same time, so as to realize the connection of thethird antenna 2053 to thefirst modem 202 and thesecond modem 203 at the same time.
Thefourth antenna 2054 is simultaneously connected to thefirst modem 202 and thesecond modem 203 through thefourth splitter 2044, and is configured to receive a 5G signal stream of the first SIM card and a 4G signal of the second SIM card in multiple periods. In particular, thefourth antenna 2054 may be connected to one end of thefourth splitter 2044, and the other end of thefourth splitter 2044 is connected to both thefirst modem 202 and thesecond modem 203, so as to enable thefourth antenna 2054 to be connected to both thefirst modem 202 and thesecond modem 203.
It is understood that the 4G signal stream and the 5G signal stream of the first SIM card refer to network signals when theelectronic device 100 wirelessly communicates with a base station or other electronic devices through information stored in the first SIM card in fourth and fifth generation mobile communication technologies, and the 4G signal of the second SIM card refers to network signals when theelectronic device 100 wirelessly communicates with a base station or other electronic devices through information stored in the second SIM card in fourth generation mobile communication technologies.
In therf circuit 200, the transmission process of the uplink signal is as follows:
thebaseband processing module 201 processes the 5G signal of the first SIM card that needs to be transmitted to the outside, and then transmits the 4G signal stream in the processed 5G signal of the first SIM card to thefirst modem 202 for modulation, and transmits the 5G signal stream in the processed 5G signal of the first SIM card to thesecond modem 203 for modulation.
Thefirst modem 202 modulates the 4G signal stream in the 5G signals of the first SIM card, transmits the modulated 4G signal stream in the 5G signals of the first SIM card to asplitter 204, transmits the modulated 4G signal stream in the 5G signals of the first SIM card to asecond antenna 2052 connected to thesplitter 204 through thesplitter 204, and transmits the modulated 4G signal stream in the 5G signals of the first SIM card to the outside through thesecond antenna 2052.
Thesecond modem 203 modulates the 5G signal stream in the 5G signals of the first SIM card, transmits the modulated 5G signal stream in the 5G signals of the first SIM card to asplitter 204, transmits the modulated 5G signal stream to afirst antenna 2051 connected to thesplitter 204 via thesplitter 204, and transmits the modulated 5G signal stream in the 5G signals of the first SIM card to the outside through thefirst antenna 2051.
In therf circuit 200, the transmission process of the downlink signal is as follows:
after receiving the 5G signal stream associated with the first SIM card from the outside, thefirst antenna 2051 transmits the receiveddownlink 5G signal stream of the first SIM card to thefirst splitter 2041 connected to thefirst antenna 2051 for splitting, and then splits to obtain the 5G signal stream associated with the first SIM card and transmits the 5G signal stream to thesecond modem 203 for demodulation.
After receiving the 4G signal stream and the 5G signal stream associated with the first SIM card and the 4G signal associated with the second SIM card from the outside, thesecond antenna 2052 transmits the receiveddownlink 4G signal stream and the 5G signal stream of the first SIM card and thedownlink 4G signal of the second SIM card to thesecond splitter 2042 connected to thesecond antenna 2052 for splitting, then the receiveddownlink 4G signal stream and the receiveddownlink 5G signal stream of the first SIM card and the receiveddownlink 4G signal stream of the second SIM card are split to obtain the 4G signal stream associated with the first SIM card and the receiveddownlink 4G signal stream associated with the second SIM card, and the obtaineddownlink 4G signal stream and the receiveddownlink 4G signal stream of the second SIM card are transmitted to thefirst modem 202 for demodulation, and the obtaineddownlink 5G signal stream associated with the first SIM.
After thethird antenna 2053 receives, from the outside, the 4G signal stream and the 5G signal stream associated with the first SIM card and the 4G signal associated with the second SIM card, the receiveddownlink 4G signal stream and the 5G signal stream of the first SIM card and thedownlink 4G signal of the second SIM card are transmitted to thethird splitter 2043 connected to thethird antenna 2053 to be split, and then the receiveddownlink 4G signal stream and the receiveddownlink 5G signal stream of the first SIM card and the receiveddownlink 4G signal stream of the second SIM card are split to obtain a 4G signal stream associated with the first SIM card and a 4G signal associated with the second SIM card, which are transmitted to thefirst modem 202 to be demodulated, and the receiveddownlink 5G signal stream associated with the first SIM card is split to obtain a 5G signal stream associated with the first SIM card and.
After receiving the 5G signal stream associated with the first SIM card and the 4G signal associated with the second SIM card from the outside, thefourth antenna 2054 transmits the receiveddownlink 5G signal stream of the first SIM card and the receiveddownlink 4G signal of the second SIM card to thefourth splitter 2044 connected to thefourth wire 2054 for splitting, then the obtained 4G signal stream associated with the second SIM card is split and transmitted to thefirst modem 202 for demodulation, and the obtained 5G signal stream associated with the first SIM card is split and transmitted to thesecond modem 203 for demodulation.
After receiving thedownlink 4G signal stream of the first SIM card and thedownlink 4G signal of the second SIM card, thefirst modem 202 demodulates thedownlink 4G signal stream of the first SIM card and thedownlink 4G signal of the second SIM card, and transmits the demodulated 4G radio frequency signal to thebaseband processing module 201 for processing.
After receiving thedownlink 5G signal stream of the first SIM card, thesecond modem 203 demodulates thedownlink 5G signal stream of the first SIM card, and transmits the demodulated 5G radio frequency signal to thebaseband processing module 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 implement, and a complete 5G network communication link requires at least 4 antennas to implement. In a communication link formed by at least 4 antennas of a 5G network, it is necessary to maintain one antenna to implement SRS (Sounding Reference Signal) communication between an electronic device and a base station. That is, in a 5G network communication link between an electronic device and a base station, it is necessary to keep an antenna transmitting SRS signals to the base station, and the base station evaluates the quality of downlink channels between the base station and the electronic device through the received SRS signals, thereby facilitating the resource allocation of the downlink channels between the base station and the electronic device. However, according to the requirements of the communication protocol, the SRS signal needs to be switched between at least 4 antennas of the 5G network communication link. That is, the electronic device sequentially transmits the SRS signal to the base station in a time division manner through each of the at least 4 antennas of the 5G network communication link. The SRS signal does not carry communication content of communication between the user and other users, and is only used for the base station to evaluate the quality of the downlink channel.
Therefore, in therf circuit 200, the SRS signal can be switched between the fourantennas 205. That is, in the SRS signal transmission period, the SRS signal is sequentially transmitted to the base station through one of the fourantennas 205 in a time division manner, and theother antennas 205 realize transmission of the user communication content between the electronic device and the base station.
Therefore, coexistence of a 5G network and a 4G network under two SIM card situations is a problem to be solved urgently in the industry, and currently, no good solution exists.
It should be noted that, in the embodiment of the present application, the operation modes of the fourantennas 205 are all set outside the transmission period of the SRS signal. That is, when none of the fourantennas 205 is used for transmitting the SRS signal, the operation mode of the fourantennas 205 is the operation mode set in the embodiment of the present application.
In the present application, in the case of two SIM cards, theelectronic device 100 communicates with the base station through both the 5G signal of the first SIM card and the 4G signal of the second SIM card. When theradio frequency circuit 200 transmits the 5G signal (including the 4G signal stream and the 5G signal stream) of the first SIM card and the 4G signal of the second SIM card, the four antennas are shared, that is, the fourantennas 205 transmit the 5G signal of the first SIM card and the 4G signal of the second SIM card, so that coexistence of the 5G network and the 4G network under the situation of two SIM cards can be realized, the number of antennas of theradio frequency circuit 200 can be reduced, occupation of the antennas on the internal space of theelectronic device 100 can be reduced, and the internal space utilization rate of the electronic device can be improved.
It should be noted that, under the 5G network architecture of NSA, the transmission of radio frequency signals needs to satisfy 4G +5G dual transmission, and the reception needs to satisfy 4G (2RX) +5G (4RX), where TX is transmission (transmit) and RX is reception (receive). The transmission of 5G signals is all in TDD (Time Division duplex) mode, and the transmission of 4G signals is in TDD and FDD (Frequency Division duplex) modes. When the transmission of the 4G signal is in FDD mode, the transmission and reception of the 4G signal can share the same path.
Referring to fig. 4-5, fig. 4 is a signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in an FDD mode, and fig. 5 is a signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in a TDD mode. At this time, theelectronic device 100 is only installed with the first SIM card and is not installed with the second SIM card. The 5G signal of the first SIM card adopts a 5G network architecture of NSA, that is, the 5G signal of the first SIM card has both a 4G signal stream and a 5G signal stream.
When the transmission of the 4G signal is in an FDD mode:
during the period T1, thefirst antenna 2051 is used for transmitting a 5G signal stream of 5G signals of the first SIM card, thesecond antenna 2052 is used for transmitting a 4G signal stream of 5G signals of the first SIM card, thethird antenna 2053 is used for receiving a 4G signal stream of 5G signals of the first SIM card, and thefourth antenna 2054 is in an idle state (i.e., an inactive state in which neither signals nor signals are transmitted). In this period, since the 4G signal stream is transmitted in an FDD manner, thesecond antenna 2052 can also be used for receiving the 4G signal stream in the 5G signal of the first SIM card. Therefore, thefirst antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and thesecond antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that dual 4G +5G transmission can be realized; thesecond antenna 2052 and thethird antenna 2053 receive a 4G signal stream in the 5G signal of the first SIM card, which may implement 4G (2 RX).
In the period T2, thefirst antenna 2051, thesecond antenna 2052, thethird antenna 2053, and thefourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
When the transmission of the 4G signal is in TDD mode:
during the period T1, thefirst antenna 2051 is used for transmitting a 5G signal stream of the 5G signals of the first SIM card for the first time, thesecond antenna 2052 is used for transmitting a 4G signal stream of the 5G signals of the first SIM card, and thethird antenna 2053 and thefourth antenna 2054 are in an idle state. In this period, since the transmission of the 4G signal stream is in TDD mode, thesecond antenna 2052 is not available for receiving the 4G signal stream in the 5G signal of the first SIM card, and the reception of the 4G signal stream in the 5G signal of the first SIM card needs to be completed in other periods or through other antennas. Therefore, thefirst antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and thesecond antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that 4G +5G dual transmission can be realized.
In the period T2, thefirst antenna 2051, thesecond antenna 2052, thethird antenna 2053, and thefourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
In the period T3, thefirst antenna 2051 is used for transmitting the 5G signal stream in the 5G signal of the first SIM card for the second time, thesecond antenna 2052 and thethird antenna 2053 are used for receiving the 4G signal stream in the 5G signal of the first SIM card, and thefourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
In the period T4, thesecond antenna 2052 and thethird antenna 2053 are used for receiving a 4G signal stream in the 5G signal of the first SIM card, and thefourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
When transmitting a 5G signal stream in the 5G signal of the first SIM card, thefirst antenna 2051 is a main set antenna, and is used for transmitting the 5G signal stream in the 5G signal of the first SIM card and receiving the 5G signal stream in the 5G signal of the first SIM card; thesecond antenna 2052, thethird antenna 2053 and thefourth antenna 2054 are all diversity antennas and are only used for receiving 5G signal streams in the 5G signals of the first SIM card.
When transmitting a 4G signal stream in the 5G signal of the first SIM card, thesecond antenna 2052 is a main set antenna, and is used for transmitting the 4G signal stream in the 5G signal of the first SIM card and receiving the 4G signal stream in the 5G signal of the first SIM card; thethird antenna 2053 is a diversity antenna and is only used for receiving 4G signal streams among the 5G signals of the first SIM card.
It should be noted that only one antenna is needed for the main set antenna to simultaneously transmit and receive the 5G signal of the first SIM card. The diversity antenna may include a plurality of antennas, thereby implementing MIMO (Multiple-Input Multiple-Output) reception of the 5G signal of the first SIM card. Thus, theradio frequency circuit 200 may implement both primary set transceiving of 5G signals and diversity MIMO reception of the first SIM card.
Referring to fig. 6 to 7, fig. 6 is another signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in an FDD mode, and fig. 7 is another signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in a TDD mode. At this time, theelectronic device 100 is not only installed with the first SIM card (the white square is the signal transmission of the first SIM card), but also installed with the second SIM card (the black square is the signal transmission of the second SIM card). The 5G signal of the first SIM card adopts a 5G network architecture of NSA, that is, the 5G signal of the first SIM card has both a 4G signal stream and a 5G signal stream.
When the transmission of the 4G signal is in an FDD mode:
during the period T1, thefirst antenna 2051 is used for transmitting a 5G signal stream of the 5G signals of the first SIM card for the first time, thesecond antenna 2052 is used for transmitting a 4G signal stream of the 5G signals of the first SIM card, thethird antenna 2053 is used for receiving a 4G signal stream of the 5G signals of the first SIM card, and thefourth antenna 2054 is in an idle state. In this period, since the 4G signal stream is transmitted in an FDD manner, thesecond antenna 2052 can also be used for receiving the 4G signal stream in the 5G signal of the first SIM card. Therefore, thefirst antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and thesecond antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that dual 4G +5G transmission can be realized; thesecond antenna 2052 and thethird antenna 2053 receive a 4G signal stream in the 5G signal of the first SIM card, which may implement 4G (2 RX).
In the period T2, thefirst antenna 2051, thesecond antenna 2052, thethird antenna 2053, and thefourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
During the period T3, thefirst antenna 2051 is used for transmitting the 5G signal stream of the 5G signals of the first SIM card for the second time, thesecond antenna 2052 and thethird antenna 2053 are used for receiving the 4G signals of the second SIM card, and thefourth antenna 2054 is in an idle state. In this time period, theradio frequency circuit 200 interrupts transmission of a 4G signal stream in a 5G signal of the first SIM card, and is configured to receive network injection information of the second SIM card, so as to achieve dual-card dual-standby of the first SIM card transmitting data traffic and the second SIM card network injection.
When the transmission of the 4G signal is in TDD mode:
during the period T1, thefirst antenna 2051 is used for transmitting a 5G signal stream of 5G signals of the first SIM card, thesecond antenna 2052 is used for transmitting a 4G signal stream of 5G signals of the first SIM card, and thethird antenna 2053 and thefourth antenna 2054 are used for receiving a 4G signal of the second SIM card. In this period, since the transmission of the 4G signal stream is in TDD mode, thesecond antenna 2052 is not available for receiving the 4G signal stream in the 5G signal of the first SIM card, and the reception of the 4G signal stream in the 5G signal of the first SIM card needs to be completed in other periods or through other antennas. Therefore, thefirst antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and thesecond antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that 4G +5G dual transmission can be realized.
In the period T2, thefirst antenna 2051, thesecond antenna 2052, thethird antenna 2053, and thefourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
In the period T3, thefirst antenna 2051 is used for transmitting a 5G signal stream in a 5G signal of the first SIM card, thesecond antenna 2052 and thethird antenna 2053 are used for receiving a 4G signal stream in the 5G signal of the first SIM card, and thefourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
In the period T4, thesecond antenna 2052 and thethird antenna 2053 are used for receiving a 4G signal stream in the 5G signal of the first SIM card, and thefourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
The difference between the signaling timing diagram shown in fig. 7 and the signaling timing diagram shown in fig. 5 is that, when the first SIM card performs 4G +5G dual transmission in a period T1, the idlethird antenna 2053 and the idlefourth antenna 2054 are used for receiving network injection information of the second SIM card, so as to achieve dual standby for the first SIM card to transmit data traffic and the second SIM card to inject network.
When transmitting a 5G signal stream in the 5G signal of the first SIM card, thefirst antenna 2051 is a main set antenna, and is used for transmitting the 5G signal stream in the 5G signal of the first SIM card and receiving the 5G signal stream in the 5G signal of the first SIM card; thesecond antenna 2052, thethird antenna 2053 and thefourth antenna 2054 are all diversity antennas and are only used for receiving 5G signal streams in the 5G signals of the first SIM card.
When transmitting a 4G signal stream in the 5G signal of the first SIM card, thesecond antenna 2052 is a main set antenna, and is used for transmitting the 4G signal stream in the 5G signal of the first SIM card and receiving the 4G signal stream in the 5G signal of the first SIM card; thethird antenna 2053 is a diversity antenna and is only used for receiving 4G signal streams among the 5G signals of the first SIM card.
When transmitting the 4G signal of the second SIM card, thesecond antenna 2052, thethird antenna 2053, and thefourth antenna 2054 are all diversity antennas and are only used for receiving the 4G signal of the second SIM card.
It should be noted that only one antenna is needed for the main set antenna to simultaneously transmit and receive the 5G signal of the first SIM card. The diversity antenna may include a plurality of antennas, thereby implementing MIMO (Multiple-Input Multiple-Output) reception of the 5G signal of the first SIM card and the 4G signal of the second SIM card. Therefore, theradio frequency circuit 200 can implement both the main set transceiving and diversity MIMO receiving of the 5G signal of the first SIM card and the diversity MIMO receiving of the 4G signal of the second SIM card, thereby implementing dual-card dual-standby with coexistence of 4G and 5G.

Thecontrol circuit 206 is configured to control thefirst modem 202 to interrupt processing of a 4G signal stream in a 5G signal of the first SIM card when processing a 4G signal of the second SIM card, so as to control the fourantennas 205 to interrupt transmission of the 4G signal stream in the 5G signal of the first SIM card when receiving the 4G signal of the second SIM card; thecontrol circuit 206 is further configured to control the first modem to interrupt processing of the 4G signal of the second SIM card when processing the 4G signal stream in the 5G signal of the first SIM card, so as to control the fourantennas 205 to interrupt receiving of the 4G signal of the second SIM card when transmitting the 4G signal stream in the 5G signal of the first SIM card. Accordingly, thecontrol circuit 206 may control thefirst modem 202 to enable the fourantennas 205 to intermittently transmit the 4G signal stream of the 5G signal of the first SIM card and the 4G signal of the second SIM card.
It is understood that thecontrol circuit 206 may also be integrated in thebaseband processing module 201, for example, thecontrol circuit 206 and thebaseband processing module 201 may be integrated as a baseband processing module chip. Furthermore, thecontrol circuit 206 may also be integrated in a processor of theelectronic device 100.
