Referring to fig. 3, fig. 3 is a schematic diagram of a first structure of a radio frequency circuit according to an embodiment of the present disclosure. Radio frequency circuit 200 includes antenna group 220 and processing module 260.
The processing module 260 transmits the 5G rf signal of the first number card 107 and the 5G rf signal of the second number card 108 through the antenna set 220. The radio frequency circuit can not only realize the 5G communication of the first number card 107, but also realize the 5G communication of the second number card 108, and realize double-card double-pass based on the 5G communication technology.

Referring to fig. 4, fig. 4 is a first timing diagram of a radio frequency circuit according to an embodiment of the present disclosure. Specifically, the transmission cycle includes a first time period T1 and a second time period T2 which are consecutive. During a first time period T1, the processing module 260 is configured to transmit a 5G radio frequency signal of the first number card 107 through the first antenna ANT0, the second antenna ANT1, the third antenna ANT2 and the fourth antenna ANT 3; in the second period, the processing module 260 is configured to transmit the 5G radio frequency signal of the second number card 108 through the first antenna ANT0, the second antenna ANT1, the third antenna ANT2, and the fourth antenna ANT 3.
The transmission cycle may further include a third period T3 and a fourth period T4, and it may also be understood that the transmission cycle includes consecutive first, second, third and fourth periods T1, T2, T3 and T4.
On the basis of the previous first time period T1 and the second time period T2, in the third time period T3, the processing module 260 is further configured to transmit the 5G radio frequency signal of the first number card 107 through the first antenna ANT0, the second antenna ANT1, the third antenna ANT2 and the fourth antenna ANT 3; during the fourth time period T4, the processing module 260 is further configured to transmit the 5G radio frequency signal of the second number card 108 through the first antenna ANT0, the second antenna ANT1, the third antenna ANT2, and the fourth antenna ANT 3.
It should be noted that, in the embodiment of the present application, the first number card 107 is in a standby state, and the second number card 108 is also in a standby state, at this time, a dual-card dual standby based on the 5G communication technology can be implemented through the time division multiplexing antenna set 220 (the first number card 107 is in standby under 5G, and the second number card 108 is in standby under 5G).
When the first number card 107 and the second number card 108 are both in a standby state, the antenna group 220 may be controlled by using the control timing of the embodiment of the present application.
Referring to fig. 5, fig. 5 is a second timing diagram of the rf circuit according to the embodiment of the present disclosure. Other control sequences may be used when the first combination card 107 is in an active state and the second combination card 108 is in a standby state. Specifically, the transmission cycle also includes a first time period T1 and a second time period T2 which are consecutive.
In a first time period, the processing module 260 is configured to transmit a 5G radio frequency signal of the first number card 107 through the first antenna ANT0, the second antenna ANT1, the third antenna ANT2 and the fourth antenna ANT 3;
in the second period, the processing module 260 is configured to transmit the 5G radio frequency signal of the first number card 107 through the first antenna ANT0, the second antenna ANT1, and the third antenna ANT2, while the processing module 260 is also configured to transmit the 5G radio frequency signal of the second number card 108 through the fourth antenna ANT 3.
It should be noted that, in the embodiment of the present application, the first number card 107 operates in the operating state of SA (i.e., the operating state of independent networking), the antenna group 220 needs to be occupied while uploading and downloading data (for example, the transceiving antennas ANT 0-3 are allocated to the first number card), and taking the case that the first number card 107 operates in N78, the operating mode of N78 is 1T4R or 2T4R (T means transmission, and R means reception). Meanwhile, in order to satisfy the condition that the second number card is in a 5G standby state, it is necessary to assign a timing sequence to the second number card, that is, the first number card is changed from 1T4R to 1T3R or from 2T4R to 2T3R, that is, a receiving timing sequence is assigned to the second number card for the second number card to receive the paging information of the base station.
Likewise, in the third period, the processing module 260 is configured to transmit the 5G radio frequency signal of the first number card 107 through the first antenna ANT0, the second antenna ANT1, the third antenna ANT2 and the fourth antenna ANT 3; during the fourth time period, the processing module 260 is configured to transmit the 5G radio frequency signal of the first number card 107 through the first antenna ANT0, the second antenna ANT1, and the third antenna ANT2, while the processing module 260 is also configured to transmit the 5G radio frequency signal of the second number card 108 through the fourth antenna ANT 3. Can be reused in one transmission period.
It should be noted that as long as the first number card satisfies 1T3R or 2T3R and the second number card remains in contact with the base station in two consecutive time periods, that is, the transceiver timing sequence of any transceiver antenna is assigned to the second number card, a mode in which one number card is in an operating state and the other number card is in a standby state can be realized.
Referring to fig. 6, fig. 6 is a third timing diagram of the rf circuit according to the embodiment of the present disclosure. Other control sequences may be used when both first number card 107 and second number card 108 are active. In any one period of the transmission cycle, the processing module 260 is configured to transmit the 5G radio frequency signal of the first number card 107 through the first antenna ANT0 and the second antenna ANT1, while the processing module 260 is also configured to transmit the 5G radio frequency signal of the second number card 108 through the third antenna ANT2 and the fourth antenna ANT 3.
For example, during the first period T1, the 5G rf signal of the first number card 107 is transmitted through the first antenna ANT0 and the second antenna ANT1, and the 5G rf signal of the second number card 108 is transmitted through the third antenna ANT2 and the fourth antenna ANT 3. In the second period T2, the 5G radio frequency signal of the first number card 107 is transmitted through the first and second antennas ANT0 and 1, and the 5G radio frequency signal of the second number card 108 is transmitted through the third and fourth antennas ANT2 and 3. In the third period T3, the 5G radio frequency signal of the first number card 107 is transmitted through the first and second antennas ANT0 and 1, and the 5G radio frequency signal of the second number card 108 is transmitted through the third and fourth antennas ANT2 and 3. During the fourth period, the 5G rf signal of the first number card 107 is transmitted through the first and second antennas ANT0 and ANT1, and the 5G rf signal of the second number card 108 is transmitted through the third and fourth antennas ANT2 and ANT 3.
It should be noted that, in the embodiment of the present application, the first number card 107 operates in an SA operating mode, data is being uploaded and downloaded, the antenna group 220 needs to be occupied (for example, the transceiving antennas ANT 0-3 are allocated to the first number card), taking the first number card 107 operates in N78 as an example, the N78 operating mode is 1T4R or 2T4R, and meanwhile, the second number card receives paging information and needs to be in an operating state, then the first number card is converted from 1T4R or 2T4R to 1T2R, the second number card is converted from a paging base station state to a 1T2R operating state, that is, the first antenna ANT0 and the second antenna ANT1 are allocated to the first number card 5G for communication, and the third antenna ANT2 and the fourth antenna ANT3 are allocated to the second number card 5G for communication, so that double-card double-pass of the two number cards can be implemented.
It can be understood that as long as in any time period of the transmission cycle, two transceiving antennas are allocated to the first number card to implement transceiving of the 5G signal of the first number card, and two transceiving antennas are allocated to the second number card to implement transceiving of the 5G signal of the second number card, the two number cards can simultaneously work in the 5G state only through 4 antennas, that is, double-card double-pass of the 5G network of the two cards is implemented.
Referring to fig. 7, fig. 7 is a schematic diagram of a second structure of the rf circuit according to the embodiment of the present disclosure. The rf circuit further comprises a modem 230, the antenna set 220 is electrically connected to the modem 230, and the modem 230 is configured to process the rf signal according to the first number card 107 and the second number card 108.
The rf circuit may use a modem 230, the antenna set 220 is electrically connected to the modem 230, the modem 230 is configured to process the rf signal according to the first number card 107 and the second number card 108 to generate a 5G signal, and the antenna set 220 transmits the 5G signal. The modem 230 can process 5G signals and can also process 2G, 3G or 4G signals for switching from 5G communication to 2G, 3G or 4G communication according to user requirements
The rf circuit may further include a front-end circuit 250, and the modem 230 is electrically connected to the antenna group 220 through the front-end circuit 250. The front-end circuit 250 may include a power amplifier through which the modem 230 transmits radio frequency signals. The front-end circuit 250 may include a power amplifier through which the modem 230 transmits radio frequency signals. The front-end circuit 250 may also include a low noise amplifier through which the modem 230 receives radio frequency signals. A power amplifier corresponds to each transmit path and a low noise amplifier corresponds to each receive path. Each antenna may be multiplexed in both the transmit path and the receive path. For example, each antenna in the corresponding antenna group has one power amplifier and one low noise amplifier, and one low noise amplifier may be provided correspondingly, and one power amplifier may be provided correspondingly to each antenna, and one of the low noise amplifiers may be connected as required.
In some embodiments, when the processing module 260 receives the switching instruction, the processing module 260 is further configured to transmit the 2G, 3G, 4G, or 5G radio frequency signal of the second number card 108 through the antenna group. It should be noted that the rf circuit 200 may transmit a 2G, 3G, 4G, or 5G rf signal based on the first number card, transmit a 2G, 3G, 4G, or 5G rf signal based on the second number card 108, and change the network status of the first number card or the second number card according to different switching instructions when receiving the switching instruction.
The rf circuit 200 may further include a baseband circuit, and the processing module 260 is connected to the modem 230 through the baseband circuit. 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 260 of the electronic device 100, or may be independent of a separate processing circuit or processing chip.
The modem 230 is connected to the baseband circuit. The modem 230 is used for processing 5G signals. For example, the modem 230 may modulate upstream signals passing through the modem 230 and demodulate downstream signals passing through the modem 230.
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 number card 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 number card in the fifth generation mobile communication technology.
It is understood that the 5g (nr) radio frequency signal of the second number card 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 number card 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 an uplink Sounding Reference Signal (SRS) of the first number 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 number card through a second transceiving antenna ANT1 during a second time period T2; transmitting an uplink sounding reference signal of the first number card through a third transceiving antenna ANT2 for a third time period T3; during a fourth time period T4, an uplink sounding reference signal of the first number card is transmitted through the fourth transceiving antenna ANT 3.
Therefore, in the radio frequency circuit, the SRS signal can be switched between the four transceiving antennas in the first group of antennas. That is, the SRS signal is sequentially transmitted to the base station through the four transceiving antennas in a time division manner, and when one of the four transceiving 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, coexistence of the 5G network and the 4G network under the situation of two number cards in the industry is a problem to be solved urgently, and no good solution exists at present.
Referring to fig. 8, fig. 8 is a schematic flowchart of a radio frequency circuit control method according to an embodiment of the present disclosure. The embodiment of the present application further provides a radio frequency circuit control method, which is applied to the radio frequency circuit and the electronic device in any of the above embodiments, for example, the radio frequency circuit includes an antenna group, where the antenna group includes at least four transceiving antennas; the transmission cycle includes a first period, a second period, a third period, and a fourth period in succession. The method specifically comprises the following steps:
301, acquiring a first state of a first number card and a second state of a second number card;
and 302, controlling the transceiving antenna according to the first state and the second state, so that the transceiving antenna transmits the 5G radio frequency signal of the first number card and the 5G radio frequency signal of the second number card.
And transmitting the 5G radio frequency signal of the first number card through the antenna group, and transmitting the 5G radio frequency signal of the second number card through the antenna group. The 5G communication of the first number card can be realized, the 5G communication of the second number card can also be realized, and double-card double-pass based on the 5G communication technology is realized.
The transmission cycle comprises a first time period and a second time period which are continuous; controlling the antenna group according to the first state and the second state may specifically include:
when the first state is a standby state and the second state is a standby state, transmitting a 5G radio frequency signal of the first number card through the first antenna, the second antenna, the third antenna and the fourth antenna in a first time period; and transmitting the 5G radio frequency signal of the second number card through the first antenna, the second antenna, the third antenna and the fourth antenna in the second time period.
The first number card is in a standby state, the second number card is also in a standby state, and at the moment, double-card double standby (the first number card 5G is in standby and the second number card 5G is in standby) based on the 5G communication technology can be realized through the time division multiplexing antenna group.
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 antenna group according to the first state and the second state may further specifically include:
and when the first state is a working state and the second state is a standby state, transmitting the 5G radio frequency signal of the first number card through the first antenna, the second antenna, the third antenna and the fourth antenna in a first time period, transmitting the 5G radio frequency signal of the first number card through the first antenna, the second antenna and the third antenna in a second time period, and simultaneously transmitting the 5G radio frequency signal of the second number card through the fourth antenna.
The first number card works in the working state of the SA (i.e. the working state of the independent network), the antenna group needs to be occupied when the first number card is uploading and downloading data (for example, the transceiving antennas ANT 0-3 are allocated to the first number card), and taking the first number card working in N78 as an example, the working mode of N78 is 1T4R or 2T4R (T means transmission, R means reception). Meanwhile, in order to satisfy the condition that the second number card is in a 5G standby state, it is necessary to assign a timing sequence to the second number card, that is, the first number card is changed from 1T4R to 1T3R or from 2T4R to 2T3R, that is, a receiving timing sequence is assigned to the second number card for the second number card to receive the paging information of the base station.
Similarly, in a third time period, the processing module is configured to transmit the 5G radio frequency signal of the first number card through the first antenna, the second antenna, the third antenna, and the fourth antenna; in a fourth time period, the processing module is configured to transmit the 5G radio frequency signal of the first number card through the first antenna, the second antenna, and the third antenna, and simultaneously the processing module is further configured to transmit the 5G radio frequency signal of the second number card through the fourth antenna. Can be reused in one transmission period.
It should be noted that as long as the first number card satisfies 1T3R or 2T3R and the second number card remains in contact with the base station in two consecutive time periods, that is, the transceiver timing sequence of any transceiver antenna is assigned to the second number card, a mode in which one number card is in an operating state and the other number card is in a standby state can be realized.
Wherein controlling the first group of antennas and the second group of antennas 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 number card through the first antenna and the second antenna, and simultaneously transmitting the 4G radio frequency signal of the second number card through the third antenna and the fourth antenna.
The first number card works in an SA working mode, data is being uploaded and downloaded, an antenna group needs to be occupied (for example, transceiving antennas ANT 0-3 are allocated to the first number card), taking the first number card as an example working in N78, the N78 working mode is 1T4R or 2T4R, or the working mode is 1T3R or 2T3R when the second number card is in a standby state, meanwhile, the second number card receives paging information and needs to be in a working state, then the first number card is converted into 1T2R from 1T4R or 2T4R or 1T3R or 2T3R, the second number card is converted into a working state of 1T2R from a paging base station state, that is, the first antenna ANT0 and the second antenna ANT1 are allocated to the first number card 5G communication, and the third antenna 2 and the fourth antenna ANT3 are allocated to the second number card 5G communication, so that the dual card number card of the dual number card can be realized.
It can be understood that as long as in any time period of the transmission cycle, two transceiving antennas are allocated to the first number card to implement transceiving of the 5G signal of the first number card, and two transceiving antennas are allocated to the second number card to implement transceiving of the 5G signal of the second number card, the two number cards can simultaneously work in the 5G state only through 4 antennas, that is, double-card double-pass of the 5G network of the two cards is implemented.
In some embodiments, the controlling the antenna group according to the first state and the second state specifically includes:
when the first number card and the second number 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 number card and the second number card to respond to the call service. Or when the first number card and the second number 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 number 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 larger than the first preset value, controlling the antenna group to transmit the data to be transmitted of the first number card or the second number card, and transmitting the data to be transmitted by using the 5G radio frequency signal of the antenna group. That is to say, when the data volume of the data to be transmitted is larger, the antenna group is used for transmitting the data to be transmitted, 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, and at this time, the electronic device may control the antenna group to respond to the transmission instruction, access the 5G NR network, and use the 5G NR network 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 5 seconds, and user experience can be greatly improved.
(5) And if the data volume of the data to be transmitted is less than the first preset value, controlling the WIFI signal device and/or the 2G, 3G and 4G network to transmit the data to be transmitted of the first number card or the second number card, and transmitting the data to be transmitted through the WIFI signal device, so that the transmission rate can be ensured, and the power consumption can be reduced.
It can be understood that, when the data volume is relatively small, the electronic device can control the WIFI signal device to transmit data, and maintain the association with the base station through the antenna group, and when there is a call, the antenna group can be used to respond to the call service. Due to the fast transmission rate of the 5G NR network, the electronic device consumes more power when using the 5G NR network for data transmission. When the data volume to be transmitted is small, the WIFI signal device and/or the antenna group 2G, 3G and 4G network are/is adopted to transmit data, and the power consumption of the electronic equipment can be reduced.
In some embodiments, when the first number card and the second number card are both in the standby state, the paging signal is received at the same time, that is, the incoming call is received at the same time, the electronic device can be displayed in a split screen mode according to the incoming call signal, and the user can select the number to be communicated according to the requirement. Or the number needing communication is connected according to the user-defined incoming call priority, or the number of the incoming call and the user are connected at the same time according to the user requirement, the three are communicated at the same time through the 5G network, and the 5G double-card double-pass is realized.
In some embodiments, the length of each signal sending timing sequence may be adjusted according to the amount of data sent, for example, in a sending period, when both the first number card and the second number card are in an operating state, the amount of data transmitted by the first number card is greater than a first preset threshold, and the amount of data transmitted by the second number card is less than the first preset threshold, the length of each signal sending timing sequence is adjusted according to the amount of data that needs to be transmitted by the second number card. For example, in one sending cycle, when the data to be sent by the second number card is 1/2 of the sending data volume in the normal time sequence, in the first time period, the second number card transmits the data volume in the time of T1 through two transceiving antennas, in the second time period, the second number card transmits the data volume in the time of 1/2T2 through two transceiving antennas, in the third time period, the second number card transmits the data volume in the time of 1/4T3 through two transceiving antennas, in the fourth time period, the second number card transmits the data volume in the time of 1/4T4 through two transceiving antennas, and the first number card performs data sending in the normal time sequence.
By adjusting the length of the sending time sequence according to the transmitted data volume, the transmitting efficiency is not influenced, the transmitting power can be reduced, and the power consumption problem of the radio frequency circuit is improved.
In some embodiments, the selection may also be made according to the current power consumption, and may also be made according to the current temperature. For example, the rate at which the rf circuit transmits the antenna signal is also constantly changing, and the corresponding transmission time period within the transmission period (which may also be understood as a fraction of the transmission period) may be selected. In addition, the radio frequency circuit can estimate the current power consumption, if the current power consumption is too large, the transmission time period in the transmission period is reduced, and if the power consumption is smaller, the transmission time period in the transmission period can be increased. The temperature of the rf circuitry (e.g., the temperature of the modem and/or power amplifier) may also be monitored, and if the current temperature is too high, the transmit time period within the transmit period may be decreased, and if the temperature is less, the transmit time period within the transmit period may be increased.
In some embodiments, the connection threshold of the 5G signal can be changed according to the current electric quantity of the electronic device to obtain the current electric quantity of the electronic device, and when the current electric quantity is smaller than the preset electric quantity, that is, under a low electric quantity, the connection threshold of the 5G network is adjusted, so that the 5G signal is connected when the 5G signal has better signal strength and signal quality, the power consumption problem of the 5G terminal is optimized, and the actual experience of a user is improved.
