On the basis of the previous first time period and the second time period, in the third time period, the processing module 240 is configured to transmit the 5G radio frequency signal of the first subscriber identity card 107 through the first antenna set 210 and the third antenna set 230; during the fourth time period, the processing module 240 is configured to transmit the 5G rf signal of the second subscriber identity card 108 through the second antenna set 220 and the third antenna set 230.

Referring to fig. 5, fig. 5 is a second timing diagram of an rf circuit according to an embodiment of the present disclosure.

It should be noted that, in the embodiment of the present application, the first subscriber identity module 107 is in the working state, and the second subscriber identity module 108 is in the standby state, and the control timing sequence of the embodiment of the present application may be used to control the first antenna set 210, the second antenna set 220, and the third antenna set 230. In this embodiment, the first subscriber identity module card 107 uploads and downloads data in an operating state, and occupies the first antenna group 210 and the third antenna group 230, for example, when the first subscriber identity module card 107 operates at N78, the operating mode of N78 is 2T4R (T means transmission, and R means reception). The first antenna group 210 and the third antenna group 230 may be time-division multiplexed to implement 2T4R, and one of the first antenna group 210 and the third antenna group 230 may also be duplexer to implement transceiving multiplexing. The second subscriber identity module card 108 is in a standby state, and needs to communicate with the base station at variable times, and the second antenna set 220 may be used to transmit the 5G radio frequency signal of the second subscriber identity module card 108.
Referring to fig. 6, fig. 6 is a third timing diagram of the rf circuit according to the embodiment of the present disclosure. Specifically, the transmission cycle also includes a first time period, a second time period, a third time period, and a fourth time period in succession. In any time period of the transmission cycle, the processing module 240 is configured to transmit the 5G radio frequency signal of the first subscriber identity card 107 through the first antenna set 210 and the third antenna set 230, and the processing module 240 is further configured to transmit the 5G radio frequency signal of the second subscriber identity card 108 through the second antenna set 220.
It should be noted that, in the embodiment of the present application, the first subscriber identity module 107 is in an operating state, and the second subscriber identity module 108 is also in an operating state, and the control timing sequence of the embodiment of the present application may be used to control the first antenna group 210, the second antenna group 220, and the third antenna group 230. In this embodiment, the first subscriber identity module card 107 uploads and downloads data in an operating state, and occupies the first antenna group 210 and the third antenna group 230, for example, when the first subscriber identity module card 107 operates at N78, the operating mode of N78 is 2T4R (T means transmission, and R means reception). The first antenna group 210 and the third antenna group 230 may be time-division multiplexed to implement 2T4R, and one of the first antenna group 210 and the third antenna group 230 may also be duplexer to implement transceiving multiplexing. The second subscriber identity module card 108 is also in operation, occupying the second antenna set 220, in the operating mode of 1T 2R. The second antenna set 220 can be time-division multiplexed to implement 1T2R, and one antenna in the second antenna set 220 can be transmit-receive multiplexed through a duplexer.
It will be appreciated that the operation of the first subscriber identity card 107 and the second subscriber identity card 108 may be interchanged depending on the size of the data volume to be transferred. The first subscriber identity module card 107 may be switched to the operating mode of 1T2R to occupy the first antenna group 210; the second subscriber identity card 108 may be switched to the 2T4R mode of operation, occupying the second antenna set 220 and the third antenna set 230. For example, when the electronic device 100 makes a call through the first user identification card 107 and downloads a movie through the second user identification card 108, the first user identification card 107 may be switched to the operation mode of 1T2R, and the second user identification card 108 may be switched to the operation mode of 2T 4R.
Referring to fig. 7, fig. 7 is a schematic diagram illustrating a second structure of a radio frequency circuit according to an embodiment of the present disclosure. Rf circuit 200 also includes a modem 250 and a front-end circuit 260.
The rf circuit 200 may use a modem 250, and the first antenna set 210, the second antenna set 220, and the third antenna set 230 are all electrically connected to the modem 250, and the modem 250 is configured to process the rf signal according to the first subscriber identity card 107 and the second subscriber identity card 108, generate a 5G signal, and transmit the 5G signal through the first antenna set 210, the second antenna set 220, and the third antenna set 230. For example, the modem 250 may generate a 5G data signal by processing the 5G signal, and then transmit the 5G data signal through the first antenna group 210, the second antenna group 220, and the third antenna group 230.
It can be understood that, compared to the existing 4G-based dual-card dual-pass scheme, in which a modem and a corresponding antenna structure are respectively disposed in the radio frequency circuit for the first subscriber identity identification card and the second subscriber identity identification card, in the embodiment of the present application, the first subscriber identity identification card 107 and the second subscriber identity identification card 108 share one modem 250, and the third antenna group 230 is time-division multiplexed, which can achieve the structural simplification of the radio frequency circuit in the electronic device, and each antenna has a larger headroom area, and can improve the signal transmission effect of the radio frequency circuit.
The rf circuit 200 may further include a front-end circuit 260, and the modem 250 is electrically connected to the first antenna set 210, the second antenna set 220, and the third antenna set 230 through the front-end circuit 260. The front-end circuit 260 may include a power amplifier through which the modem 250 transmits a radio frequency signal; the front-end circuit 260 may also include a low noise amplifier through which the modem 250 receives radio frequency signals. A power amplifier corresponds to each transmit path and a low noise amplifier corresponds to each receive path, and each antenna can be multiplexed in both the transmit path and the receive path. For example, there is one power amplifier and one low noise amplifier corresponding to each antenna in the first antenna group 210, and there may also be one low noise amplifier corresponding to the first antenna group 210 and one power amplifier corresponding to each antenna, and the low noise amplifier may select one of the antennas to connect as needed. The second antenna group 220 and the third antenna group 230 may employ a similar structure as the first antenna group 210.
The rf circuit 200 may further include a baseband circuit through which the processing module 240 is connected to the modem 250. The baseband circuit is used for processing communication data of the radio frequency circuit 200 and controlling the working state of each device in the radio frequency circuit 200 according to the interaction information with the base station or the network server. It is understood that the baseband circuit may be integrated into the processing module 240 of the electronic device 100, or may be independent of a separate processing circuit or processing chip.
The modem 250 is connected to the baseband circuit. The modem 250 is used for processing 5G signals. For example, the modem 250 may modulate upstream signals passing through the modem 250 and demodulate downstream signals passing through the modem 250.
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.
It is understood that the 5g (nr) radio frequency signal of the first subscriber identity card 107 refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through the information stored in the first subscriber identity card 107 in the fifth generation mobile communication technology.
It is understood that the 5g (na) rf signal of the second subscriber identity card 108 refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through the information stored in the second subscriber identity card 108 in the fifth generation mobile communication technology.
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.
For example, the processing module controls the modem to transmit the uplink sounding reference signal of the first subscriber identity module card through the first transceiving antenna ANT0 for a first time period T1 in another transmission cycle; transmitting an uplink sounding reference signal of the first subscriber identity module card through a second transceiving antenna ANT1 during a second time period T2; transmitting an uplink sounding reference signal of the first subscriber identity module card through a third transceiving antenna ANT2 for a third time period T3; during a fourth time period T4, the uplink sounding reference signal of the first subscriber identity module card is transmitted through the fourth transceiving antenna ANT 3.
Therefore, in the radio frequency circuit, the SRS signal may be switched between the four transceiver antennas, that is, the SRS signal is sequentially transmitted to the base station through the four transceiver antennas in a time division manner, and when one of the four transceiver antennas is used for transmitting the SRS signal, the other three antennas realize transmission of the communication content of the user between the electronic device and the base station.
Therefore, the realization of the double-card double-pass based on the 5G communication technology in the industry is a problem to be solved urgently, and no good solution exists at present.
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, the 5G radio frequency signals include 4G signal streams and 5G signal streams.
Referring to fig. 8, fig. 8 is a schematic flowchart illustrating a radio frequency circuit control method according to an embodiment of the present disclosure. The embodiment of the application also provides a radio frequency circuit control method, and the radio frequency circuit control method is applied to the radio frequency circuit and the electronic equipment in any embodiment. Illustratively, the radio frequency circuit includes a first antenna group including at least two antennas, a second antenna group including at least two antennas, and a third antenna group including at least two antennas; the transmission cycle includes a first period, a second period, a third period, and a fourth period in succession. The radio frequency circuit control method may specifically include:
301, acquiring a first state of a first user identification card and a second state of a second user identification card;
and 302, controlling the first antenna group, the second antenna group and the third antenna group according to the first state and the second state, so that the first antenna group transmits the 5G radio frequency signal of the first subscriber identity module card, the second antenna group transmits the 5G radio frequency signal of the second subscriber identity module card, and the third antenna group transmits the 5G radio frequency signals of the first subscriber identity module card and the second subscriber identity module card.
The 5G radio frequency signals of the first user identity identification card are transmitted through the first antenna group, the 5G radio frequency signals of the second user identity identification card are transmitted through the second antenna group, and the 5G radio frequency signals of the first user identity identification card and the second user identity identification card are transmitted through the third antenna group, so that not only can 5G communication of the first user identity identification card be realized, but also 5G communication of the second user identity identification card can be realized, and double-card double-pass based on the 5G communication technology can be realized.
Wherein the transmission cycle comprises a first time period and a second time period which are continuous; controlling the first antenna group, the second antenna group, and the third antenna group according to the first state and the second state may specifically include:
and when the first state is a standby state and the second state is a standby state, transmitting the 5G radio frequency signal of the first subscriber identity module card through the first antenna group and the third antenna group in a first time period, and transmitting the 5G radio frequency signal of the second subscriber identity module card through the second antenna group and the third antenna group in a second time period.
The first user identification card is in a standby state, the second user identification card is also in a standby state, and at the moment, double-card double standby based on the 5G communication technology can be realized through the first antenna group, the second antenna group and the third antenna group (the first user identification card is in 5G standby, and the second user identification card is also in 5G standby).
It should be noted that the transmission cycle further includes a third time period and a fourth time period, and the third time period and the fourth time period have the same control method as the first time period and the second time period.
The transmission cycle comprises a first time period and a second time period which are continuous; controlling the first antenna group, the second antenna group, and the third antenna group according to the first state and the second state may specifically include:
when the first state is the working state and the second state is the standby state, the 5G radio frequency signal of the first user identity identification card is transmitted through the first antenna group and the third antenna group in the first time period, the 5G radio frequency signal of the first user identity identification card is transmitted through the first antenna group and the third antenna group in the second time period, and meanwhile, the 5G radio frequency signal of the second user identity identification card is transmitted through the second antenna group.
The first user identification card is in a working state, and the second user identification card is in a standby state. At this time, the first subscriber identity module uploads and downloads data in a working state, and occupies the first antenna group and the third antenna group, for example, the first subscriber identity module operates at N78, and the operating mode of N78 is 2T 4R. The first antenna group and the third antenna group can be time-division multiplexed to realize 2T4R, and one antenna in the first antenna group and the third antenna group can be used for transceiving and multiplexing through a duplexer. The second subscriber identity module card is in a standby state and needs to communicate with the base station at variable time, and the second antenna group can be used for transmitting the 5G radio frequency signal of the second subscriber identity module card.
It should be noted that the transmission cycle further includes a third time period and a fourth time period, and the third time period and the fourth time period have the same control method as the first time period and the second time period.
Wherein the transmission cycle comprises at least two time periods; controlling the first antenna group, the second antenna group, and the third antenna group according to the first state and the second state may further specifically include:
and when the first state is the working state and the second state is the working state, in any time period in the transmission cycle, transmitting the 5G radio frequency signal of the first user identity identification card through the first antenna group and the third antenna group, and simultaneously transmitting the 5G radio frequency signal of the second user identity identification card through the second antenna group.
The first user identification card is in a working state, and the second user identification card is also in a working state. At this time, the first subscriber identity module uploads and downloads data in a working state, and occupies the first antenna group and the third antenna group, for example, the first subscriber identity module operates at N78, and the operating mode of N78 is 2T 4R. The first antenna group and the third antenna group can be time-division multiplexed to realize 2T4R, and one antenna in the first antenna group and the third antenna group can be used for transceiving and multiplexing through a duplexer. The second user identification card is also in a working state, occupies the second antenna group, and has a working mode of 1T 2R. The time division multiplexing of the second antenna group can be realized to realize 1T2R, and the duplexer can also realize the transceiving multiplexing of one antenna in the second antenna group.
It will be appreciated that the first subscriber identity card and the second subscriber identity card may operate interchangeably depending on the amount of data being transferred. The first subscriber identity module card can be switched to a working mode of 1T2R to occupy a first antenna group; the second subscriber identity module card can be switched to the working mode of 2T4R, and occupies the second antenna group and the third antenna group. For example, when the electronic device makes a call through the first user identification card and downloads a movie through the second user identification card, the first user identification card may be switched to the operation mode of 1T2R, and the second user identification card may be switched to the operation mode of 2T 4R.
Wherein controlling the first antenna group, the second antenna group, and the third antenna group according to the first state and the second state may further specifically include:
when the first user identification card and the second user identification card are both in a working state, detecting the network connection state of a Wi-Fi signal device in the electronic equipment;
and if the Wi-Fi signal device is in a connection state, controlling the Wi-Fi signal device to perform data transmission, and controlling the first user identification card and the second user identification card to be used for responding to the mobile service.
Or:
when the first user identification card and the second user identification card are both in a working state, detecting the network connection state of a Wi-Fi signal device in the electronic equipment;
if the Wi-Fi signal device is in a connection state, acquiring the data volume of data to be transmitted of a 5G radio frequency signal of the first user identity identification card;
judging whether the data volume of the data to be transmitted is larger than a first preset value or not;
and if the data volume of the data to be transmitted is greater than or equal to a first preset value, controlling the first antenna group and the third antenna group to transmit the data to be transmitted of the first user identification card, and controlling the second antenna group to respond to the mobile service of the second user identification card. That is to say, when the data volume of the data to be transmitted is larger, the first antenna group and the third antenna group are used for transmitting the data to be transmitted of the 5G radio frequency signal of the first subscriber identity module card, and the data to be transmitted is transmitted at a high transmission rate of the 5G NR network.
For example, when a user needs to download a full-high-definition movie, because the data volume of the full-high-definition movie is usually large, some full-high-definition movies may even reach 40G, at this time, the electronic device may control the first antenna group and the third antenna group to respond to the transmission instruction, the first antenna group and the third antenna group are accessed to the 5G NR network, and the 5G NR network is used to download the full-high-definition movie. Because the transmission rate of the 5G NR network is fast, for example, the transmission rate of the 5G NR network can reach 10Gbps, which means that the electronic device can complete downloading of a full high-definition movie in less than 4 seconds, and user experience can be greatly improved.
And if the data volume of the data to be transmitted is smaller than the first preset value, controlling the Wi-Fi signal device to transmit the data. The first antenna group and the third antenna group are used for keeping contact with the base station, and when the first subscriber identity identification card has mobile services such as call calling, the mobile services can be responded by using the first antenna group and the third antenna group; the second antenna group is also used for keeping contact with the base station, and when the second subscriber identity card has mobile services such as call calling, the second antenna group can be used for responding to the mobile services.
Or:
when the first user identification card and the second user identification card are both in a working state, detecting the network connection state of a Wi-Fi signal device in the electronic equipment;
if the Wi-Fi signal device is in a connection state, acquiring the data volume of data to be transmitted of a 5G radio frequency signal of a second user identity identification card;
judging whether the data volume of the data to be transmitted is larger than a second preset value or not;
and if the data volume of the data to be transmitted is greater than or equal to a second preset value, controlling the first antenna group to respond to the mobile service of the first user identification card, and controlling the second antenna group and the third antenna group to transmit the data to be transmitted of the second user identification card. That is to say, when the data volume of the data to be transmitted is larger, the data to be transmitted of the second subscriber identity module card 5G radio frequency signal is transmitted by using the second antenna group and the third antenna group, and the data to be transmitted is transmitted at a high transmission rate through the 5G NR network.
For example, when a user needs to download a full-high-definition movie, because the data volume of the full-high-definition movie is usually large, some full-high-definition movies may even reach 40G, at this time, the electronic device may control the second antenna group and the third antenna group to respond to the transmission instruction, the second antenna group and the third antenna group are accessed to the 5G NR network, and the 5G NR network is used to download the full-high-definition movie. Because the transmission rate of the 5G NR network is fast, for example, the transmission rate of the 5G NR network can reach 10Gbps, which means that the electronic device can complete downloading of a full high-definition movie in less than 4 seconds, and user experience can be greatly improved.
And if the data volume of the data to be transmitted is less than a second preset value, controlling the Wi-Fi signal device to transmit the data. The first antenna group is used for keeping contact with the base station, and when the first subscriber identity identification card has mobile services such as call calling, the first antenna group can be used for responding to the mobile services; the second antenna set and the third antenna set are also used for keeping contact with the base station, and when the second subscriber identity card has a mobile service, such as a call, the mobile service can be responded by using the second antenna set and the third antenna set.
It can be understood that when the data volume of the data to be transmitted is small, the electronic device may control the Wi-Fi signaling device to transmit the data, and keep in contact with the base station through the first antenna group, the second antenna group and the third antenna group, and when there is a call, the first antenna group, the second antenna group and the third antenna group may be used to respond to the call service. Due to the fact that the transmission rate of the 5G NR network is high, when the electronic equipment uses the 5G NR network for data transmission, more electric quantity can be consumed, and when the data quantity to be transmitted is small, the Wi-Fi signal device is adopted for data transmission, so that the power consumption of the electronic equipment can be reduced.
Referring to fig. 9, fig. 9 is a schematic diagram of a graphical user interface displayed when the electronic device executes the radio frequency circuit control method according to the embodiment of the present application. When the first user identification card and the second user identification card are both in working states, whether the first user identification card and the second user identification card have incoming calls at the same time is judged. If the two user identification cards have incoming calls, the electronic equipment can automatically display incoming call information in a split screen mode, and a user can select to respond to the incoming call of only one user identification card or respond to the incoming calls of the two user identification cards simultaneously according to actual conditions. For example, when an incoming call of a first subscriber identity card is associated with an incoming call of a second subscriber identity card, a user can simultaneously respond to the incoming calls of the two subscriber identity cards, so that an incoming call object from the first subscriber identity card, an incoming call object from the second subscriber identity card and the user can form a communication group, and the three can communicate with each other, for example, the communication group can be used for a group conference, a friend chat and other scenes. Therefore, the electronic equipment can realize the multi-person conversation function under the condition of no data transmission signal.
For example, the user may also classify two user identification cards according to time, for example, a first user identification card may be used for responding to the data service in the working time, a second user identification card may be used for responding to the data service in the non-working time, and the electronic device preferentially responds to the data service in the corresponding time period according to the difference in the time period. For example, when an incoming call comes in from both the first user identification card and the second user identification card during work hours, the incoming call request of the first user identification card is responded preferentially; and in the non-working time, when the first user identification card and the second user identification card have incoming calls, preferentially responding to the incoming call request of the second user identification card. Therefore, the intelligence of double-card double-pass can be improved.
For example, the user may set a first user identification card to be used for data transmission, and a second user identification card to be used for mobile data services such as a call service. The user can transmit the data resource of the first user identification card through the first antenna group, respond to the mobile data service of the second user identification card through the second antenna group, and transmit the data resource of the first user identification card or respond to the mobile data service of the second user identification card through the third antenna group. For example, a user can transmit a 5G radio frequency signal of a first user identification card through the first antenna group and the third antenna group, so that the user can play games on the internet, respond to incoming calls of a second user identification card through the second antenna group, and use the dual-card dual-pass function of the electronic device to realize playing games and listening to calls. For example, a user can transmit a 5G radio frequency signal of a first user identification card through the first antenna group and the third antenna group, so that the user can communicate with the internet of things to realize automatic driving, respond to an incoming call of a second user identification card through the second antenna group, and answer the call while driving by using a double-card double-pass function of the electronic equipment.
