It is understood, however, that the cover plate 102 may be a glass cover plate of sapphire material.

The middle frame 103 may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. The middle frame 103 is used for providing a supporting function for the electronic elements or functional components in the electronic device 100, so as to mount the electronic elements or functional components in the electronic device 100 together.

The middle frame 103 and the rear cover 106 may together form a housing of the electronic device 100, for accommodating or mounting electronic elements, functional components, and the like of the electronic device 100. For example, the display screen 101 may be mounted on the housing. In addition, functional components such as a camera, a receiver, a circuit board, and a battery of the electronic apparatus 100 may be mounted on the center frame 103 to be fixed.

The circuit board 104 may be a motherboard of the electronic device 100. Wherein, the circuit board 104 is provided with a radio frequency circuit. The radio frequency circuitry is used to enable wireless communication between the electronic device 100 and a base station or other electronic device.

The battery 105 is mounted inside a casing formed by the middle frame 103 and the rear cover 106 together. For example, the battery 105 may be mounted on the middle frame 103. Meanwhile, the battery 105 is electrically connected to the circuit board 104 to enable the battery 105 to power the electronic device 100.

The first SIM card 107 may be mounted on the bezel 103 or on the circuit board 104 inside the electronic device. The first SIM card 107 may serve as an information storage for storing identification information of the user, such as a telephone number for representing the identity of the user.

In the embodiment of the present application, the circuit board 104 is provided with a radio frequency circuit 200. The radio frequency circuit 200 is used to enable wireless communication between the electronic device 100 and a base station or other electronic devices.

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.

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. The radio frequency circuit 200 comprises a processing module 201, a first modem 202, a second modem 203 and four antennas 204.

The four antennas 204 include a first antenna 2041, a second antenna 2042, a third antenna 2043, and a fourth antenna 2044.

The first modem 202 is used for processing 5G radio frequency signals. The input of the first modem 202 is connected to the processing module 201 and the output of the first modem 202 is connected to four antennas 204.

The second modem 203 is used for processing 4G radio frequency signals. The input of the second modem 203 is connected to the processing module 201, and the output of the second modem 203 is connected to four antennas 204.

Referring to fig. 4, the processing module 201 controls the first modem 202 to transmit a first Sounding Reference Signal (SRS) via the first antenna 2041 during a first time period T1; transmitting the sounding reference signal of the first identity through the second antenna 2042 for a second time period T2; transmitting the sounding reference signal of the first identity through the third antenna 2043 for a third time period T3; during a fourth time period T4, the first identified sounding reference signal is transmitted by the fourth antenna 2044. It should be noted that, in the drawing, ANT1 is a first antenna 2041, ANT2 is a first antenna 2042, ANT3 is a first antenna 2043, and ANT4 is a first antenna 2044, which are not repeated herein.

The first time period T1, the second time period T2, the third time period T3, and the fourth time period T4 are consecutive time periods in one cycle, and in any one of the first time period T1, the second time period T2, the third time period T3, and the fourth time period T4, the second identifier is screened through two antennas 204 that do not transmit sounding reference signals.

In one period, the processing module 201 sequentially transmits a sounding reference signal (SRS signal) of a first identifier through the first antenna 2041, the second antenna 2042, the third antenna 2043 and the fourth antenna 2044; meanwhile, in any time period in one period, the second identifier is networked through two antennas 204 which do not transmit sounding reference signals. In the process of transmitting the sounding reference signal (SRS signal) of the first identifier, for the network injection timing sequence of the second identifier, the 4G and 5G antennas 204 are completely multiplexed, and it is not necessary to separately set the 4G antenna 204 and the 5G antenna 204, which saves the number of the antennas 204, and at the same time, correspondingly reduces the headroom area of the antennas 204, saves the space in the electronic device, improves the space utilization rate inside the electronic device, and facilitates the lightening and thinning of the electronic device. For example, one cycle includes four consecutive time periods T1, T2, T3, and T4, and when the sounding reference signal of the first identifier is transmitted through the first antenna 2041 in the time period T1, the second antenna 2042, the third antenna 2043, and the fourth antenna 2044 do not transmit the sounding reference signal of the first identifier or are in an idle state, then two antennas 204 may be selected from the second antenna 2042, the third antenna 2043, and the fourth antenna 2044 to perform network injection for the second identifier. Therefore, the method does not affect the emission of the sounding reference signal (SRS signal) of the first identifier, can also inject the network for the second identifier, and realizes the simultaneous standby of the first identifier and the second identifier.

The network injection for the second identity may be network injection for a 4G LTE of the second identity.

It should be noted that the first identifier or the second identifier may be understood as user identification, such as phone number stored in the SIM card. The first identifier or the second identifier may also be information such as a phone number directly burned into the electronic device, that is, the first identifier or the second identifier may be a module that is present inside the electronic device without depending on the SIM card, and the module has the main or all functions of the SIM card. For ease of understanding, in some embodiments, the first identity may be understood as a first SIM card 107 and the second identity may be understood as a second SIM card 108.

The rf circuit 200 may further include a baseband circuit, and the processing module 201 is connected to the second modem 203 and the first modem 202 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 201 of the electronic device 100, or may be independent of a separate processing circuit or processing chip.

The first modem 202 is connected to the baseband circuitry. The first modem 202 is used for processing 5G rf signals. For example, the first modem 202 may modulate upstream signals passing through the first modem 202 and demodulate downstream signals passing through the first modem 202.

The second modem 203 may modulate upstream signals passing through the second modem 203 and demodulate downstream signals passing through the second modem 203.

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.

The second modem 203 and the first modem 202 may be connected to the same antenna via a splitter. The splitter is used for combining and splitting the radio frequency signals. That is, the splitter may be configured to combine two uplink signals into one uplink signal and to split one downlink signal into two downlink signals.

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

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

It is understood that the 5G signal of the first SIM card refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through information stored in the first SIM card in a fifth generation mobile communication technology.

It is understood that the 4G signal of the second SIM card refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through information stored in the second SIM card in a fourth generation mobile communication technology.

Each antenna 204 is connected to the second modem 203 and the first modem 202. Wherein, the antenna 204 can be connected to one end of the splitter, and the other end of the splitter is connected to the second modem 203 and the first modem 202 at the same time, so as to realize the connection of the antenna 204 with the second modem 203 and the first modem 202 at the same time. Each antenna 204 is used for transmitting 5G signals of the first SIM card and for transmitting 4G signals of the second SIM card.

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

the processing module 201 processes a 5G signal of the first SIM card and a 4G signal of the second SIM card that need to be transmitted to the outside, and then transmits the processed 5G signal of the first SIM card to the first modem 202 for modulation, and transmits the processed 4G signal of the second SIM card to the second modem 203 for modulation.

The first modem 202 modulates the 5G signal of the first SIM card, transmits the modulated 5G signal of the first SIM card to an antenna 204, and transmits the modulated 5G signal of the first SIM card to the outside through the antenna 204.

The second modem 203 modulates the 4G signal of the second SIM card, transmits the modulated 4G signal of the second SIM card to an antenna 204, and transmits the modulated 4G signal of the second SIM card to the outside through the antenna 204.

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

after receiving the 5G signal associated with the first SIM card from the outside, the one or more antennas 204 transmit the received downlink 5G signal of the first SIM card to the first modem 202 for demodulation. After receiving the 5G signal associated with the first SIM card from the outside, the one or more antennas 204 transmit the received downstream 5G signal of the first SIM card to a splitter connected to the antennas 204, and transmit the signal to the first modem 202 via the splitter for demodulation. It is understood that the 5G signal associated with the first SIM card refers to the 5G signal when the base station or other electronic equipment performs wireless communication with the electronic equipment 100 through the subscriber identity information stored in the first SIM card (for example, the first telephone number stored in the first SIM card and used for representing the subscriber identity).

After receiving the downlink 5G signal of the first SIM card, the first modem 202 demodulates the downlink 5G signal of the first SIM card, and transmits the demodulated 5G signal to the processing module 201 for processing.

After receiving the 4G signal associated with the second SIM card from the outside, the one or more antennas 204 transmit the received downlink 4G signal of the second SIM card to the second modem 203 for demodulation. After receiving the 4G signal associated with the second SIM card from the outside, the one or more antennas 204 transmit the received downlink 4G signal of the second SIM card to a splitter connected to the antennas 204, and transmit the signal to the second modem 203 for demodulation. It is understood that the 4G signal associated with the second SIM card refers to the 4G signal when the base station or other electronic equipment performs wireless communication with the electronic equipment 100 through the subscriber identity information stored in the second SIM card (for example, the second telephone number stored in the second SIM card for representing the subscriber identity).

After receiving the downlink 4G signal of the second SIM card, the second modem 203 demodulates the downlink 4G signal of the second SIM card, and transmits the demodulated 5G signal to the baseband circuit for processing.

In the present application, in the case of two SIM cards, the electronic 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 the radio frequency circuit 200 transmits the 5G signal of the first SIM card and the 4G signal of the second SIM card, the four antennas are shared to 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 the radio frequency circuit 200 can be reduced, the occupation of the antennas on the internal space of the electronic device 100 can be reduced, and the internal space utilization rate of the electronic device can be improved.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a second structure of a radio frequency circuit according to an embodiment of the present disclosure. The first modem 202 may transmit the first identified sounding reference signal via the four antennas 204 in sequence during one period, which may be implemented by the switching element 206. Specifically, the output of the first modem 202 is connected to four antennas 204 through a switch element 206, and the switch element 206 is used to connect the output of the first modem 202 to different antennas 204 at different time periods.

The switch element 206 may include four output terminals, each of which is connected to one of the antennas 204, a control terminal of the switch element 206 may control which output terminal the input terminal is conducted, and the control terminal of the switch element 206 may be connected to the first modem 202, so that the first modem 202 transmits the sounding reference signal of the first identifier sequentially through the first antenna 2041, the second antenna 2042, the third antenna 2043, and the fourth antenna 2044.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a third structure of a radio frequency circuit according to an embodiment of the present disclosure. The number of outputs of the first modem 202 may be one or two. When the number of the output terminals of the first modem is two, the output terminal of the first modem 202 includes a first output terminal 2021 and a second output terminal 2022, the first output terminal 2021 and the second output terminal 2022 are connected to the four antennas 204 through the switch element 206, and the first output terminal 2021 and the second output terminal 2022 are used for outputting two paths of sounding reference signals.

Referring to fig. 7, the processing module 201 controls the first modem 202 to transmit two sounding reference signals (PA 1SRS and PA2 SRS) of the first identifier through the first antenna 2041 and the second antenna 2042 during the first time period T1; in a second time period T2, the two paths of sounding reference signals of the first identifier are transmitted through the second antenna 2042 and the third antenna 2043; in a third time period T3, the two paths of sounding reference signals of the first identifier are transmitted through the third antenna 2043 and the fourth antenna 2044; during a fourth time period T4, the first identified two sounding reference signals are transmitted through the fourth antenna 2044 and the first antenna 2041.

Specifically, one period includes four time periods T1, T2, T3, and T4, in the time period T1, the first antenna 2041 transmits the first path of sounding reference signal PA1SRS of the first identifier, and the second antenna 2042 transmits the second path of sounding reference signal PA2SRS of the first identifier, at this time, the third antenna 2043 and the fourth antenna 2044 do not transmit sounding reference signals or are idle, and may be used to perform network injection for the second identifier. Similar control logic may be employed for the T2, T3 and T4 time periods. It should be noted that, in the four time periods T1, T2, T3, and T4, only one time period may be selected as the second identifier, or two or more time periods may be selected as the identifier.

It should be noted that the first modem 202 and the second modem 203 are also connected to the antenna 204 through a power amplifier 205. When the first modem 202 has two outputs, there are a first power amplifier 2051 and a second power amplifier 2052, respectively.

Referring to fig. 8, an embodiment of the present application further provides an antenna using method, where the antenna using method is correspondingly applied to the radio frequency circuit in the foregoing embodiment, and the antenna using method specifically includes:

301, transmitting a first identified sounding reference signal through a first antenna in a first time period;

302, transmitting the first identified sounding reference signal through a second antenna in a second time period;

303, transmitting the sounding reference signal of the first identifier through a third antenna in a third time period;

304, transmitting the first identified sounding reference signal through the fourth antenna during a fourth time period;

305, wherein the first time period, the second time period, the third time period and the fourth time period are consecutive time periods in one cycle, and in any one of the first time period, the second time period, the third time period and the fourth time period, the second identifier is screened by two antennas which do not transmit sounding reference signals.

With reference to fig. 3 and 4, in one period, a sounding reference signal (SRS signal) of the first identifier is transmitted sequentially through the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the fourth antenna ANT 4; meanwhile, in any time period in one period, the second mark is marked with a network through two antennas which do not transmit the sounding reference signal. In the process of transmitting the sounding reference signal (SRS signal) of the first identifier, for the network injection time sequence of the second identifier, the antennas of 4G and 5G are completely multiplexed, so that the antennas of 4G and 5G do not need to be independently arranged, the number of the antennas is reduced, meanwhile, the clearance area of the antennas is correspondingly reduced, the space in the electronic equipment is saved, the space utilization rate inside the electronic equipment is improved, and the electronic equipment is convenient to lighten and thin. For example, one cycle includes four periods T1, T2, T3, and T4, which are consecutive, and when the sounding reference signal (SRS signal) of the first identifier is transmitted through the first antenna ANT1 in the period T1, the second antenna ANT2, the third antenna ANT3, and the fourth antenna ANT4 do not transmit the sounding reference signal of the first identifier or are in an idle state, two antennas may be selected from the second antenna ANT2, the third antenna ANT3, and the fourth antenna ANT4 to mesh with the second identifier. Therefore, the first identifier is not influenced to transmit sounding reference signals (SRS signals), and the second identifier can be networked, so that the first identifier and the second identifier can be simultaneously standby.

The network injection for the second identity may be network injection for a 4G LTE of the second identity. That is, in one period, the four antennas sequentially transmit the 5G sounding reference signals (SRS signals) of the first identifier, and meanwhile, in this period, two antennas that do not transmit the 5G sounding reference signals are used for network injection for the 4G of the second identifier. Two SIM cards are realized, one is standby in a 5G environment and one is standby in a 4G environment.

It should be noted that the first identifier or the second identifier may be understood as user identification, such as phone number stored in the SIM card. The first identifier or the second identifier may also be information such as a phone number directly burned into the electronic device, that is, a module existing inside the electronic device without depending on the SIM card, where the module has the main or all functions of the SIM card. For ease of understanding, in some embodiments, the first identity may be understood as a first SIM card and the second identity may be understood as a second SIM card.

The step 305 may not be executed after the previous steps 301 to 304 are completed, but may be executed in the execution process of the four steps 301 to 304 as required, for example, executed at the same time as the step 301, or may be executed together with any one of the steps 302 to 304.

Referring to fig. 9, in any one of the first time period, the second time period, the third time period, and the fourth time period, the network injection for the second identifier through two antennas that do not transmit sounding reference signals includes:

in any one time period of the first time period, the second time period, the third time period and the fourth time period, performing network injection on the second identification through two antennas which do not transmit the sounding reference signals;

acquiring an idle antenna which does not transmit the sounding reference signal and does not mark the second identifier;

the first identified 4G signal is transmitted through the idle antenna.

In a period, not only can the 5G sounding reference signals of the first identification be sequentially transmitted through the 4 antennas, but also the 4G network can be annotated for the second identification, the 4G signals of the first identification can be transmitted, the antennas can be fully multiplexed, and the use efficiency of the antennas is improved. For example, one cycle includes four consecutive time periods T1, T2, T3, and T4, and when the sounding reference signal of the first identifier is transmitted through the first antenna in the time period T1, the 4G signal of the first identifier is transmitted through the second antenna at the same time, and when the sounding reference signal of the first identifier is transmitted through the second antenna in the time period T2, the second identifier is screened through the third antenna and the fourth antenna.

It should be noted that the foregoing embodiment is only an exemplary example, that is, the foregoing embodiment only provides one combination manner, and only needs to guarantee that two receiving paths with corresponding second identifiers (it may also be understood that two antennas are used for network injection for the second identifiers) and one 4G transmitting path with corresponding first identifiers (it may also be understood that one antenna is used for transmitting 4G signals of the first identifiers) are guaranteed in one SRS Switching period, but a single path (one antenna) may only have one state in one time.

Referring to fig. 10, in any one of the first time period, the second time period, the third time period, and the fourth time period, the network injection for the second identifier through two antennas that do not transmit sounding reference signals includes:

in any one time period of the first time period, the second time period, the third time period and the fourth time period, network injection is carried out on the second identification through two antennas which do not transmit sounding reference signals;

the first identified 4G signal is received through two idle antennas.

In a period, the 5G sounding reference signals of the first identification can be sequentially transmitted through the 4 antennae, the 4G network can be injected for the second identification, the 4G signals of the first identification can be received, the antennae can be fully multiplexed, and the use efficiency of the antennae is improved. For example, one cycle includes four consecutive time segments T1, T2, T3, and T4, and when the sounding reference signal of the first identifier is transmitted through the first antenna in the time segment T1, the 4G signal of the first identifier is simultaneously received through the second antenna and the third antenna, and when the sounding reference signal of the first identifier is transmitted through the second antenna in the time segment T2, the second identifier is screened through the third antenna and the fourth antenna.

It should be noted that the foregoing embodiment is only an exemplary example, that is, the foregoing embodiment only provides one combination manner, and only needs to guarantee that two receiving paths with corresponding second identifiers (it may be understood that two antennas are used for network injection of the second identifiers) and 2 4G receiving paths with corresponding first identifiers (it may be understood that two antennas are used for transmitting 4G signals of the first identifiers) are guaranteed in one SRS Switching period, but a single path (it may be understood that one antenna) may only have one state in one time.

Wherein, in any one of the first time period, the second time period, the third time period and the fourth time period, the network injection for the second identifier through two antennas which do not transmit sounding reference signals comprises:

in one time period of the first time period, the second time period, the third time period and the fourth time period, network injection is carried out on the second identification through two antennas which do not transmit sounding reference signals;

and in another time period of the first time period, the second time period, the third time period and the fourth time period, the second identifier is screened through two antennas which do not transmit the sounding reference signals.

In one period, the 5G detection reference signals of the first identification can be transmitted in sequence through the 4 antennae, the network can be injected for the 4G of the second identification twice in one period, the antennae are fully multiplexed, the service efficiency of the antennae is improved, the success rate of the network injection for the 4G of the second identification is improved, and the standby reliability of the dual-card is ensured. For example, one cycle includes four consecutive time periods T1, T2, T3, and T4, and when the sounding reference signal of the first identifier is transmitted through the first antenna in the time period T1, the second identifier is simultaneously screened through the second antenna and the third antenna, and when the sounding reference signal of the first identifier is transmitted through the second antenna in the time period T2, the second identifier is screened through the third antenna and the fourth antenna.

It should be noted that the foregoing embodiment is only an exemplary example, that is, the foregoing embodiment only provides one combination manner, and only needs to guarantee that two receiving paths with corresponding second identifiers (it may also be understood that two antennas are used for network injection for the second identifier) are guaranteed in one SRS Switching period, but a single path (it may also be understood as one antenna) may only have one state in one time.

It is understood that in one SRS Switching period, in any one of the periods, the antenna that does not transmit the SRS Switching signal may be used to implement other functions, such as transmitting the 4G signal of the first identifier, receiving the 4G signal of the first identifier, networking the second identifier, and so on. For example, in the T1 period, the SRS Switching signal is transmitted through the first antenna, the second antenna transmits the first identified 4G signal or receives the first identified 4G signal, and the third antenna and the fourth antenna perform network injection for the second identifier. Currently, other idle antennas may be selected or idle antennas may be selected in other time periods when transmitting or receiving the 4G signal of the first identifier, and other idle antennas may be selected to perform network injection for the second identifier or idle antennas in other time periods may be selected to perform network injection for the second identifier.

For another example, in the period T1, the SRS Switching signal is transmitted through the first antenna, and the 4G signal of the first identifier is transmitted through the second antenna; in the T2 time period, transmitting an SRS Switching signal through a second antenna, and simultaneously, network-injecting a third antenna and a fourth antenna for a second identifier; in the T3 time period, transmitting an SRS Switching signal through a third antenna, and simultaneously receiving a first identified 4G signal through a fourth antenna; and in the T4 time period, transmitting an SRS Switching signal through a fourth antenna, and simultaneously, networking the second identifier by the first antenna and the second antenna. That is, in one SRS Switching period, each time period may be multiplexed by using the idle antennas, for example, one or more times of transmitting the 4G signal of the first identifier, one or more times of receiving the 4G signal of the first identifier, and one or more times of selecting to network the second identifier.

For example, one cycle includes four time periods T1, T2, T3, and T4, in the time period T1, the first antenna ANT1 transmits the first path of sounding reference signal PA1SRS of the first identifier, and the second antenna ANT2 transmits the second path of sounding reference signal PA2SRS of the first identifier, at this time, the third antenna ANT3 and the fourth antenna ANT4 do not transmit sounding reference signals or are idle, and may be used to perform network injection for the second identifier. Similar control logic may be employed for the T2, T3 and T4 time periods. It should be noted that, in the four time periods T1, T2, T3, and T4, only one time period may be selected as the second identifier, or two or more time periods may be selected as the identifier.

It should be noted that, the second identifier may be screened by two antennas that do not transmit sounding reference signals in any one of the first time period T1, the second time period T2, the third time period T3, and the fourth time period T4. And in any two time periods or three time periods or four time periods of the four time periods, the two antennas which do not transmit the sounding reference signals can be used for network injection of the second identifier.
