Description

Method for transmitting a transmission signal in an electronic device and an electronic device supporting multiple SIMs

[0001] Various embodiments of the present disclosure relate to an electronic device and a method of transmitting a transmission signal in an electronic device supporting multiple SIMs.

[0002] In a wireless communication system, an electronic device (e.g., user equipment (UE)) can access a wireless communication network to use voice communication or data communication services at a fixed location or while moving. To provide communication services to an electronic device, an appropriate authentication process may be required. For example, a UICC (universal integrated circuit card) may be inserted into the electronic device, and authentication may be performed between the electronic device and a mobile network operator (MNO) server through a universal subscriber identity module (USIM) installed inside the UICC. The UICC may be called a SIM (subscriber identity module) card for the GSM (global system for mobile communications) method, or a USIM (universal subscriber identity module) card for the WCDMA (wideband code division multiple access), LTE (long term evolution), or NR (new radio) method.

[0003] When a user of an electronic device subscribes to a wireless communication service provided by a telecommunications carrier, the telecommunications carrier provides the user with a UICC (e.g., a SIM card or USIM card), and the user can insert the UICC provided into his or her electronic device. When the UICC is inserted into the electronic device, the USIM application installed in the UICC is executed, and an appropriate authentication process can be performed with the telecommunications carrier's server, which stores the same value, using the IMSI (international mobile subscriber identity) value and the encryption key value for authentication stored in the UICC. After the appropriate authentication process is performed, the wireless communication service can be used.

[0004] An electronic device can support two or more SIMs. When it supports two SIMs, it can be called a dual SIM electronic device, and a device that supports multiple SIMs can be called a multi SIM electronic device. A dual SIM or multi SIM electronic device can support multiple SIMs, and each SIM can be associated with a different subscription. Signals associated with each of the multiple SIMs or signals corresponding to each of the multiple SIMs can be transmitted or received by the electronic device to or from a network. A mode in which each of the signals associated with each of the multiple SIMs cannot be transmitted or received substantially simultaneously can be called a dual SIM dual standby (DSDS) mode. In DSDS mode, while a signal based on one SIM is being transmitted or received, a signal based on another SIM cannot be transmitted or received, and thus the other SIM can be set to standby mode. A mode in which each of the signals associated with each of the multiple SIMs can be transmitted or received substantially simultaneously can be called a dual SIM dual active (DSDA) mode. In DSDA mode, signals based on one SIM can be transmitted or received while signals based on the other SIM are being transmitted or received, and both SIMs can be activated simultaneously.

[0005] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0006] According to one embodiment, an electronic device may include a first radio frequency (RF) circuit including a first amplifier. The electronic device may include a second RF circuit including a second amplifier. The electronic device may include a memory storing instructions. The electronic device may include at least one processor. The instructions, when executed by the at least one processor, may cause the electronic device to operate in a first transmission mode by transmitting a first signal corresponding to a first subscriber identity module (SIM) through the first RF circuit and simultaneously transmitting a second signal corresponding to a second SIM through the second RF circuit. The instructions may cause the electronic device to switch from the first transmission mode to a second transmission mode by alternately transmitting the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one of the first RF circuit and the second RF circuit based on determining that a first condition is satisfied.

[0007] According to one embodiment, a method of operating an electronic device, including a first radio frequency (RF) circuit including a first amplifier, a second RF circuit including a second amplifier, and at least one processor, may include operating the electronic device in a first transmission mode by transmitting a first signal corresponding to a first subscriber identity module (SIM) through the first RF circuit and simultaneously transmitting a second signal corresponding to a second SIM through the second RF circuit. The method of operating the electronic device may include switching from the first transmission mode to a second transmission mode by alternately transmitting the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one of the first RF circuit and the second RF circuit based on confirming that a first condition is satisfied.

[0008] According to one embodiment, a storage medium storing at least one computer-readable instruction may be provided. The at least one instruction, when executed by at least a portion of at least one processor of an electronic device, may cause the electronic device to perform at least one operation. The at least one operation may include operating the electronic device in a first transmission mode by transmitting a first signal corresponding to a first subscriber identity module (SIM) through a first radio frequency (RF) circuit and simultaneously transmitting a second signal corresponding to a second SIM through a second RF circuit. The at least one operation may include switching from the first transmission mode to a second transmission mode by alternately transmitting the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one of the first RF circuit and the second RF circuit based on a determination that a first condition is satisfied.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0055] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0058] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0059] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108).

For example, the electronic device (101) may include a first slot (not shown) and a second slot (not shown), which are first structures, therein to accommodate the first SIM (111) and the second SIM (112), respectively. In this case, the meaning of the electronic device (101) including the first SIM (111) and the second SIM (112) may mean that the first SIM (111) and the second SIM (112) are mounted on the electronic device (101), and it will be understood by those skilled in the art that it may not necessarily mean that the electronic device (101) includes the first SIM (111) and the second SIM (112). As another example, at least one of the first SIM (111) and the second SIM (112) may include an embedded subscriber identity module (eSIM). The eSIM may also be referred to as an eUICC.

[0063] According to various embodiments, the first SIM (111) is a SIM subscribed to a telecommunications carrier of the first communication network (111a), and the electronic device (101) can receive wireless communication services by connecting to the first communication network (111a) using the first SIM (111). The second SIM (112) is a SIM subscribed to a telecommunications carrier of the second communication network (112a), and the electronic device (101) can receive wireless communication services by connecting to the second communication network (112a) using the second SIM (112). As another example, although not illustrated, the first SIM (111) and the second SIM (112) may be SIMs subscribed to a telecommunications carrier of the same telecommunications network. For example, the carriers of the first communication network and the second communication network may be the same. For example, the first SIM (111) and the second SIM (112) may each be SIMs corresponding to different subscriber information subscribed to the same telecommunications carrier.

The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and may support 5G network communication through the established communication channel. According to various embodiments, the second cellular network (294) may be a 5G network defined by the 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0066] The first communication processor (212) can transmit or receive data with the second communication processor (214). For example, data classified to be transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit or receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit or receive various information, such as sensing information, information on output strength, and resource block (RB) allocation information, with the second communication processor (214).

[0067] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit or receive data through the second communication processor (214) and the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit or receive data through the HS-UART interface or the PCIe interface with the processor (120) (e.g., application processor), but there is no limitation on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using shared memory with the processor (120) (e.g., application processor).

[0068] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented in a single chip or a single package. According to various embodiments, the first communication processor (212) or the second communication processor (214) may be formed in a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2B, the integrated communication processor (260) may support functions for communicating with both the first cellular network (292) and the second cellular network (294).

[0069] The first RFIC (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in a first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).

[0070] The second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0071] The third RFIC (226) can convert the baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).

[0072] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separately from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0073] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to various embodiments, when the first RFIC (222) and the second RFIC (224) are implemented as a single chip or a single package in FIG. 2A or FIG. 2B, they may be implemented as an integrated RFIC (223) as illustrated in FIG. 2C. In this case, the integrated RFIC (223) may be connected to the first RFFE (232) and the second RFFE (234), such that the integrated RFIC (223) may convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to one embodiment, at least one antenna module among the first antenna module (242) or the second antenna module (244) may be omitted or combined with another antenna module to process RF signals of a corresponding plurality of bands.

[0074] According to one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications by the transmission line. Due to this, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0075] According to one embodiment, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.

[0076] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in connection with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (230) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0077] FIG. 3 illustrates a block diagram of an electronic device according to various embodiments.

[0078] According to various embodiments, the electronic device (101) may include a processor (120), a unified communication processor (260), an RF circuit (320), and at least one of a first SIM (331) or a second SIM (341). At least one of the first SIM (331) or the second SIM (341) may be an rSIM. In this case, the electronic device (101) may further include at least one slot for connection with the rSIM. In addition, as described above, the rSIM is removable from the electronic device (101), and is not necessarily a component of the electronic device (101). At least one of the first SIM (331) or the second SIM (341) may be an eSIM.

[0079] According to various embodiments, the unified communication processor (260) may support a specified number of SIMs (e.g., two). Those skilled in the art will appreciate that, instead of the unified communication processor (260), a first communication processor (e.g., the first communication processor (212) of FIG. 2A) and a second communication processor (e.g., the second communication processor (214) of FIG. 2A) may be implemented to be included in the electronic device (101). Although not shown, the electronic device (101) may include more than the specified number of SIMs (e.g., two rSIMs and one eSIM). In this case, the electronic device (101) may further include a switch (not shown) for switching SIM connections between the multiple SIMs and the unified communication processor (260).

[0080] According to various embodiments, the integrated communication processor (260) may support the establishment of a communication channel in a band to be used for wireless communication and network communication through the established communication channel. For example, the integrated communication processor (260) may support at least one of second generation (2G), 3G, 4G, or 5G network communication.

[0081] According to various embodiments, the RF circuit (320) may include, for example, at least one of a radio frequency integrated circuit (RFIC), a radio frequency front end (RFFE), or an antenna module. The RF circuit (320) may process data (e.g., a baseband signal) output from the integrated communication processor (260) into an RF signal and transmit the RF signal through the antenna module. Alternatively, the RF circuit (320) may convert an RF signal received through the antenna module into a baseband signal and transmit the baseband signal to the integrated communication processor (260). The RF circuit (320) may process an RF signal or a baseband signal according to a communication method supported by the integrated communication processor (260), and there is no limitation on the type of the RF circuit (320).

[0082] According to various embodiments, the RFFE may include at least one amplifier for amplifying and transmitting a transmission signal. The RF circuit (320) may include the at least one amplifier included in the RFFE. In addition to the at least one amplifier, the RF circuit (320) may further include at least one component included in the RFIC, the RFFE, or the antenna module. For example, the RF circuit (320) may include at least one amplifier and an antenna switching module (ASM). According to various embodiments, the RF circuit (320) may include at least one amplifier, an ASM, and at least one low noise amplifier (LNA).

[0083] According to various embodiments, the interface between the components may be implemented as, for example, a general purpose input / output (GPIO), a universal asynchronous receiver / transmitter (UART) (e.g., a high speed-UART (HS-UART) or a peripheral component interconnect bus express (PCIe) interface), but the type is not limited thereto. Alternatively, at least some of the components may exchange control information or packet data information, for example, using a shared memory. Meanwhile, in the embodiment of FIG. 3, the processor (120) and the integrated communication processor (260) are illustrated as being different hardware, but this is merely exemplary, and the processor (120) and the integrated communication processor (260) may be implemented as different hardware, but according to another implementation example, the processor (120) and the integrated communication processor (260) may be implemented in a single chip.

[0084] The integrated communication processor (260) can obtain stored information from the first SIM (331) and the second SIM (341). For example, the stored information can include at least one of an integrated circuit card identifier (ICCID), an IMSI, home public land mobile network (HPLMN) related information, or a mobile subscriber international ISDN number (MSISIDN). The stored information can also be named an elementary file (EF). The integrated communication processor (260) can perform an authentication procedure for network communication corresponding to the first SIM (331) and / or the second SIM (341) based on the information stored in the acquired first SIM (331) and / or the second SIM (341) through the RF circuit (320). If the authentication is successful, the integrated communication processor (260) can perform network communication corresponding to the first SIM (331) and / or the second SIM (341) through the RF circuit (320).

[0085] According to various embodiments, the integrated communication processor (260) may perform network communications of dual SIMs according to the first SIM (331) or the second SIM (341). The RF circuit (320) may provide multiple RF paths. Depending on the selection of the RF path, the dual SIMs may operate in either the DSDS mode or the DSDA mode. According to various embodiments, the integrated communication processor (260) may select an RF path corresponding to the first SIM (331) and an RF path corresponding to the second SIM (341) so that the first SIM (331) and the second SIM (341) may operate in the DSDA mode. For example, the integrated communication processor (260) may identify a second RF path that can operate simultaneously with the first RF path corresponding to the first SIM (331). The integrated communication processor (260) may, in a cell selection operation for the second SIM (341), preferentially search for a frequency corresponding to the second RF path. For example, the integrated communication processor (260), in a cell reselection operation for the second SIM (341), may preferentially search for a frequency band corresponding to the second RF path, or may adjust the cell reselection priority for a cell (or frequency band) supported by the second RF path. For example, if DSDA mode operation is possible, the integrated communication processor (260) may maintain camp-on on a cell corresponding to the second SIM (341) (e.g., a cell camped on using the second SIM (341).

[0086] According to various embodiments, the integrated communication processor (260) may include two protocol stacks for processing SIMs (e.g., protocol stacks according to ISO7816), and the first SIM (331) and the second SIM (332) may be connected to the two protocol stacks. For example, a first slot (not shown) may be connected to one protocol stack, and a second slot (not shown) may be connected to another protocol stack.

[0087] FIGS. 4A and 4B illustrate block diagrams of electronic devices according to various embodiments.

[0088] Referring to FIG. 4A, an electronic device according to various embodiments (e.g., the electronic device (101) of FIG. 1A) may include a processor (120), an integrated communication processor (260), an RFIC (410), a first RFFE (431), a second RFEE (432), a first antenna (441), a second antenna (442), a third antenna (443), a fourth antenna (444), a first switch (451), or a second switch (452). A first SIM (331) and a second SIM (341) may be connected to the integrated communication processor (260).

[0089] According to various embodiments, the RFIC (410) may, upon transmission, convert a baseband signal generated by the integrated communication processor (260) into a radio frequency (RF) signal used in a first communication network (e.g., the first communication network (111a) of FIG. 1B) or a second communication network (e.g., the second communication network (112a) of FIG. 1B). For example, the RFIC (410) may transmit an RF signal used in the first communication network to a first antenna (441) or a fourth antenna (444) via a first RFFE (431) and a first switch (451). The RFIC (410) may transmit an RF signal used in the first communication network or the second communication network to a second antenna (442) or a third antenna (443) via a second RFFE (432) and a second switch (452). According to various embodiments, the RFIC (410) may transmit an RF signal corresponding to a first communication network to a first antenna (441) or a fourth antenna (444) through a first RFFE (431), and may transmit an RF signal corresponding to a second communication network to a second antenna (442) or a third antenna (443) through a second RFFE (432).

[0090] According to various embodiments, a transmission RF path transmitted from the RFIC (410) through the first RFFE (431) and the first switch (451) to the first antenna (441) may be referred to as a 'first RF path (RF path 1)'. A transmission RF path transmitted from the RFIC (410) through the first RFFE (431) and the first switch (451) to the fourth antenna (444) may be referred to as a 'fourth RF path (RF path 4)'. Here, the RF path may mean, for example, a path through which a baseband signal output from the integrated communication processor (260) is converted into an RF signal and the RF signal is radiated as a physical communication signal through at least one of the antennas (441, 442, 443, 444), or at least one hardware associated with the RF path. In various embodiments, the act of performing communication based on a particular RF path may include the act of transmitting and / or receiving a signal via at least some hardware included in the particular RF path. Alternatively, the act of performing communication based on the particular RF path may include at least one first operation causing at least one first hardware (e.g., an RFIC and / or an RFFE) associated with the particular RF path to operate and / or a second operation controlling at least one second hardware (e.g., an antenna) associated with the particular RF path to be connected to the RF path (e.g., controlling on / off of at least one switch).

[0091] According to various embodiments, the RFIC (410) may, upon transmission, convert a baseband signal generated by the integrated communication processor (260) into a radio frequency (RF) signal used in a first communication network or a second communication network. For example, the RFIC (410) may transmit the RF signal used in the first communication network or the second communication network to a second antenna (442) or a third antenna (443) via a second RFFE (432) and a second switch (452).

[0092] According to various embodiments, a transmission RF path transmitted from the RFIC (410) through the second RFFE (432) and the second switch (452) to the second antenna (442) may be referred to as a 'second RF path (RF path 2)'. A transmission RF path transmitted from the RFIC (410) through the second RFFE (432) and the second switch (452) to the third antenna (443) may be referred to as a 'third RF path (RF path 3)'. According to various embodiments, the first communication network and the second communication network may be communication networks corresponding to different radio access technologies (RATs). For example, the first communication network may be a 5G network, and the second communication network may be a legacy network (e.g., an LTE network). If the first communication network is a 5G network, one of the first RFFE (431) or the second RFFE (432) may be designed to be suitable for processing signals corresponding to the 5G network, and the other may be designed to be suitable for processing signals corresponding to a legacy network. In another embodiment, the first communication network and the second communication network may be communication networks corresponding to the same RAT.

[0093] Referring to FIG. 4B, according to various embodiments, the first switch (451) and the second switch (452) may be connected to each other. Accordingly, for example, a signal from the first RFFE (431) may be provided to at least some of the first antenna (441), the second antenna (442), the third antenna (443), or the fourth antenna (444) based on the on / off state of each of the sub-switches included in the first switch (451) and the second switch (452).

[0095] According to various embodiments, the first RFFE (431) may communicate with a 5G network. In this case, the first RFFE (431) may further include additional components different from the second RFFE (432) for signal processing suited to the characteristics of the 5G network or for supporting multi-bands. For example, the first RFFE (431) may include a front end module (FEM) (460) and a first single pole double throw (SPDT) switch (470).

[0096] According to various embodiments, the FEM (460) may include a power amplifier (PA) (461) and a PA ET IC (envelop tracking IC) (464). According to various embodiments, the PA ET IC (464) may be included within the FEM (460) as illustrated in FIG. 5, or may be connected to the FEM (460) externally. The PA ET IC (464) may control the Vcc of the PA (461) under the control of the integrated communication processor (260) or the RFIC (410). The above PA ET IC (envelop tracking IC) (464) can operate in a plurality of modes (e.g., envelope tracking (ET) mode, average power tracking (APT) mode, or maximum power mode (e.g., APT full bias or battery direct)) under the control of the integrated communication processor (260) or RFIC (410).

[0097] Hereinafter, specific embodiments will be described with reference to FIGS. 6 to 23.

[0098] FIG. 6 illustrates a block diagram of an electronic device according to various embodiments.

[0099] Referring to FIG. 6, an electronic device according to various embodiments (e.g., the electronic device (101) of FIG. 1A) may include an RFIC (610), a first RFFE (621), a second RFEE (622), a first antenna (ANT0) (631), a second antenna (ANT1) (632), a third antenna (ANT2) (633), and a fourth antenna (ANT3) (634). The first RFFE (621) may include a first amplifier (621a), a first switch (621b), a first-first low-noise amplifier (621c), and a first-second low-noise amplifier (621d). The second RFFE (622) may include a second amplifier (622a), a second switch (622b), a second-first low-noise amplifier (622c), and a second-second low-noise amplifier (622d).

[0100] According to various embodiments, the RFIC (610) may include at least two transmit chains (Tx chains). For example, a first transmit chain of the RFIC (610) may be connected to a first RFFE (621). A second transmit chain of the RFIC (610) may be connected to a second RFFE (622).

[0101] According to various embodiments, the RFIC (610) may transmit a first signal (Tx0) corresponding to the first SIM to the first RFFE (621) through the first transmission chain. The first signal transmitted from the RFIC (610) may be input to the first amplifier (621a) of the first RFFE (621) and amplified. The first signal amplified in the first amplifier (621a) may be transmitted to the first network through the first antenna (631) via the first switch (621b). The received signal corresponding to the first SIM transmitted from the first network may be received through the first antenna (631) and / or the fourth antenna (634). For example, the 1-1 reception signal (RX0) corresponding to the 1st SIM transmitted from the 1st network may be received through the 1st antenna (631) and transmitted to the RFIC (610) via the 1st switch (621b) and the 1-1st low-noise amplifier (621c). The 1-2 reception signal (RX1) corresponding to the 1st SIM transmitted from the 1st network may be received through the 4th antenna (634) and transmitted to the RFIC (610) via the 2-2nd low-noise amplifier (622d).

[0102] According to various embodiments, the RFIC (610) may transmit a second signal (Tx0) corresponding to a second SIM to a second RFFE (622) through a second transmission chain. The second signal transmitted from the RFIC (610) may be input to a second amplifier (622a) of the second RFFE (622) and amplified. The second signal amplified in the second amplifier (622a) may be transmitted to a second network through a third antenna (633) via a second switch (622b). A reception signal corresponding to the second SIM transmitted from the second network may be received through the second antenna (632) and / or the third antenna (633). For example, the 2-1 reception signal (RX3) corresponding to the 2nd SIM transmitted from the 2nd network may be received through the 3rd antenna (633) and transmitted to the RFIC (610) via the 2nd switch (622b) and the 2-1st low-noise amplifier (622c). The 2-2 reception signal (RX2) corresponding to the 2nd SIM transmitted from the 2nd network may be received through the 2nd antenna (632) and transmitted to the RFIC (610) via the 1-2nd low-noise amplifier (621d).

[0103] Referring to FIG. 6, according to various embodiments, when an electronic device (101) includes an RFIC (610) including two transmission chains, two RFFEs (e.g., a first RFFE (621) and a second RFFE (622)) for transmitting transmission signals, and at least two antennas (e.g., a first antenna (631), a second antenna (632), a third antenna (633), and a fourth antenna (634)), two transmission signals corresponding to two SIMs (e.g., a first signal corresponding to the first SIM and a second signal corresponding to the second SIM) can be simultaneously transmitted. Simultaneously transmitting a first signal corresponding to the first SIM and a second signal corresponding to the second SIM through a first RF circuit (e.g., a first RFFE (621)) and a second RF circuit (e.g., a second RFFE (622)), respectively, may be referred to as full DSDA or full Tx concurrency DSDA, but the embodiments described below are not limited to the term. For example, the electronic device (101) may support full DSDA or full Tx concurrency DSDA.

[0104] FIG. 7 illustrates transmission of a transmission signal of an electronic device according to various embodiments.

[0105] Referring to FIG. 7, an electronic device according to various embodiments (e.g., electronic device (101) of FIG. 1A) may include a first RFFE (711), a second RFEE (712), a first antenna (721), and a second antenna (722). As described above in FIG. 6, when the electronic device (101) includes two RFFEs (e.g., a first RFFE (711) and a second RFFE (712)) for transmitting transmission signals and at least two antennas (e.g., a first antenna (721) and a second antenna (722)), two transmission signals corresponding to two SIMs (e.g., a first signal corresponding to the first SIM and a second signal corresponding to the second SIM) can be transmitted simultaneously. For example, the electronic device (101) can support full DSDA or full simultaneous transmission DSDA. According to various embodiments, the electronic device (101) can include at least two RFFEs (e.g., a first RFFE (711) and a second RFFE (712)) capable of processing transmission signals for a specific frequency band (e.g., a mid band (MB) and a high band (HB) (e.g., 1.7 GHz to 2.5 GHz)). When RFFE (712) is included, two transmission signals for the specific frequency band can be transmitted simultaneously.

[0106] According to various embodiments, the first RFFE (711) may transmit a second signal corresponding to the second SIM through the first antenna (721) disposed at the bottom of the electronic device (101). The second RFFE (712) may transmit a first signal corresponding to the first SIM through the second antenna (722) disposed at the top of the electronic device (101). For example, the first signal corresponding to the first SIM and the second signal corresponding to the second SIM may be simultaneously transmitted through the second RFFE (712) and the first RFFE (711), respectively, thereby operating as full DSDA or full simultaneous transmission DSDA.

[0107] FIG. 8 illustrates a block diagram of an electronic device according to various embodiments.

[0108] Referring to FIG. 8, an electronic device according to various embodiments (e.g., the electronic device (101) of FIG. 1A) may include an RFIC (810), a first RFFE (821), a second RFEE (822), a third RFFE (823), a fourth RFFE (824), a first antenna (ANT0) (831), a second antenna (ANT1) (832), a third antenna (ANT2) (833), and a fourth antenna (ANT3) (834). The first RFFE (821) may include an amplifier (821a), a first switch (821b), a first band filter (821c), a second switch (821d), a first-first low-noise amplifier (821e), and a first-second low-noise amplifier (821f). The second RFFE (822) may include a second low-noise amplifier (822a), a second band filter (822b), and a second low-noise amplifier (822c). The third RFFE (823) may include a third-first low-noise amplifier (823a), a third band filter (823b), and a third-second low-noise amplifier (823c). The fourth RFFE (824) may include a fourth-first low-noise amplifier (824a), a fourth band filter (824b), and a fourth-second low-noise amplifier (824c).

[0109] Referring to FIG. 8, according to various embodiments, when the electronic device (101) includes only one RFFE (e.g., the first RFFE (821)) for transmitting a transmission signal for a specific frequency band, it may not be able to simultaneously transmit two transmission signals corresponding to two SIMs (e.g., a first signal corresponding to the first SIM and a second signal corresponding to the second SIM). For example, the electronic device (101) may not support full DSDA or full simultaneous transmission DSDA. For example, when there is only one transmission RFFE for transmitting a first signal corresponding to the first SIM and a second signal corresponding to the second SIM, the electronic device (101) may alternately transmit the first signal and the second signal (e.g., alternately) through the one transmission RFFE. Alternately transmitting a first signal corresponding to the first SIM and a second signal corresponding to the second SIM through one RF circuit (e.g., the first RF circuit) may be referred to as Tx Sharing, but the embodiments described below are not limited to the term. For example, if there is only one Tx RFFE for transmitting a first signal corresponding to the first SIM and a second signal corresponding to the second SIM, Tx Sharing may be operated.

[0110] FIG. 9 illustrates transmission of a transmission signal of an electronic device according to various embodiments.

[0111] Referring to FIG. 9, an electronic device (e.g., the electronic device (101) of FIG. 1A) according to various embodiments may include an RFFE (920), a first antenna (931), and a second antenna (932). As described above with reference to FIG. 8, if the electronic device (101) includes only one RFFE (e.g., the RFFE (920)) capable of processing a transmission signal for a specific frequency band (e.g., a low band (LB)), full DSDA may not be supported and thus may operate in Tx sharing. For example, as illustrated in FIG. 9, a first signal corresponding to a first SIM and a second signal corresponding to a second SIM may be transmitted alternately over time.

[0112] Fig. 10 illustrates a block diagram of an electronic device according to various embodiments. Referring to Fig. 10, a plurality of RFFEs (1011, 1012, 1013, 1021, 1022, 1023, 1031, 1032, 1033, 1040) may be connected to at least one RFIC (410). Multiple RFFEs (1011, 1012, 1013, 1013, 1021, 1022, 1023, 1031, 1032, 1033, 1040) can be connected to multiple antennas (1051, 1052, 1061, 1062, 1071, 1072, 1073, 1081, 1091, 1092).

[0113] According to various embodiments, the 1-1 RFFE (1011) and the 2-1 RFFE (1021) may be connected to a first main antenna (1051) and a second main antenna (1061), respectively. The 1-2 RFFE (1012) and the 1-3 RFFE (1013) may be connected to a first sub antenna (1052) to provide diversity with the first main antenna (1051). The 2-2 RFFE (1022) and the 2-3 RFFE (1023) may be connected to a second sub antenna (1062) to provide diversity with the second main antenna (1061). The 3-1 RFFE (1031) may be connected to two third main antennas (1071, 1072) to provide MIMO. Additionally, the 3-2 RFFE (1032) and the 3-3 RFFE (1033) can be connected to a third sub antenna (1073) through a duplexer to provide MIMO or diversity with the third main antennas (1071, 1072). The 5th antenna (1081) can be directly connected to the RFIC (410) without going through the RFFE. The 6-1st antenna (1091) and the 6-2nd antenna (1092) can also be directly connected to the RFIC (410) without going through the RFFE, and can provide MIMO or diversity through two antennas. The 4th RFFE (1040) can be connected to two WiFi antennas (e.g., WiFi 1 and WiFi 2).

[0114] According to various embodiments, at least one of the RFFEs of FIG. 10 may correspond to any one of the first RFFE (431), the second RFFE (432) described above in FIG. 4a, FIG. 4b, or FIG. 5. At least one of the antennas of FIG. 10 may correspond to any one of the first antenna (441), the second antenna (442), the third antenna (443), or the fourth antenna (444) described above in FIG. 4a, FIG. 4b, or FIG. 5.

[0115] FIG. 11 illustrates a block diagram of an electronic device according to various embodiments.

[0116] Referring to FIG. 11, an electronic device (e.g., electronic device (101) of FIG. 1A) according to various embodiments may include a communication processor (1101), an RFIC (1110), a first RFFE (1120), a second RFEE (1130), a third RFFE (1140), a fourth RFEE (1150), a first antenna (ANT0) (1171), a second antenna (ANT1) (1172), a third antenna (ANT2) (1173), and a fourth antenna (ANT3) (1174).

[0117] According to various embodiments, the first RFFE (1120) may process a low-band (LB) frequency signal. The first RFFE (1120) may include a first amplifier (1121) that amplifies the low-band frequency signal. The first amplifier (1121) may be controlled by a first power management IC (PMIC) (1161). The low-band frequency signal amplified by the first amplifier (1121) may be transmitted through a first antenna (1171).

[0118] According to various embodiments, the second RFFE (1130) can process a mid-band (MB) frequency signal and a high-band (HB) frequency signal. The second RFFE (1130) can include a second-first amplifier (1131) that amplifies a mid-band frequency signal and a second-second amplifier (1132) that amplifies a high-band frequency signal. The second-first amplifier (1131) and the second-second amplifier (1132) can be controlled by a second PMIC (1162). The mid-band frequency signal amplified by the second-first amplifier (1131) or the high-band frequency signal amplified by the second-second amplifier (1132) can be transmitted through a second antenna (1172).

[0119] According to various embodiments, the third RFFE (1140) may process a mid-band (MB) frequency signal and a high-band (HB) frequency signal. The third RFFE (1140) may include a 3-1 amplifier (1141) that amplifies a mid-band frequency signal and a 3-2 amplifier (1142) that amplifies a high-band frequency signal. The 3-1 amplifier (1141) and the 3-2 amplifier (1142) may be controlled by a third PMIC (1163). The mid-band frequency signal amplified by the 3-1 amplifier (1141) or the high-band frequency signal amplified by the 3-2 amplifier (1142) may be transmitted through a third antenna (1173).

[0120] According to various embodiments, the fourth RFFE (1150) may process an ultra-high band (UHB) frequency signal. The fourth RFFE (1150) may include a fourth amplifier (1151) that amplifies the ultra-high band frequency signal. The fourth amplifier (1151) may be controlled by the third PMIC (1163). The ultra-high band frequency signal amplified by the fourth amplifier (1151) may be transmitted through the fourth antenna (1174).

[0121] According to various embodiments, referring to FIG. 11, when a first signal corresponding to a first SIM is a low-band frequency signal and a second signal corresponding to a second SIM is a low-band frequency signal, since there is only one RFFE (e.g., the first RFFE (1120)) supporting the corresponding frequency band, full DSDA or full simultaneous transmission DSDA cannot be supported during DSDA operation, and transmission sharing (Tx sharing) can be operated through time division.

[0122] According to various embodiments, when a first signal corresponding to a first SIM is a mid-band frequency signal and a second signal corresponding to a second SIM is a mid-band frequency signal, since there are two RFFEs (e.g., a second RFFE (1130) and a third RFFE (1140)) supporting the corresponding frequency bands, full DSDA or full simultaneous transmission DSDA can be supported during DSDA operation. For example, a first signal corresponding to the first SIM can be transmitted through the second RFFE (1130), and at the same time, a second signal corresponding to the second SIM can be transmitted through the third RFFE (1140).

[0123] According to various embodiments, when the first signal corresponding to the first SIM is a low-band frequency signal and the second signal corresponding to the second SIM is a mid-band frequency signal, since there are three RFFEs (e.g., the first RFFE (1120), the second RFFE (1130), and the third RFFE (1140)) supporting the corresponding frequency bands, full DSDA or full simultaneous transmission DSDA can be supported during DSDA operation. For example, the first signal corresponding to the first SIM can be transmitted through the first RFFE (1120), and at the same time, the second signal corresponding to the second SIM can be transmitted through the second RFFE (1130) or the third RFFE (1140).

[0124] According to various embodiments, when the first signal corresponding to the first SIM is an ultra-high band frequency signal and the second signal corresponding to the second SIM is an ultra-high band frequency signal, since there is only one RFFE (e.g., the fourth RFFE (1150)) supporting the corresponding frequency band, full DSDA or full simultaneous transmission DSDA cannot be supported during DSDA operation, and transmission sharing can be operated. If one more RFFE capable of processing the ultra-high band frequency signal is added, making the total number two, the electronic device (101) can support full DSDA or full simultaneous transmission DSDA during DSDA operation.

[0125] FIG. 12 illustrates transmission of a transmission signal of an electronic device according to various embodiments.

[0126] Referring to FIG. 12, an electronic device according to various embodiments (e.g., electronic device (101) of FIG. 1A) may include an RFFE (1210), a first antenna (1221), and a second antenna (1222).

[0127] According to various embodiments, the RFFE (1210) may process a low-band frequency signal. The RFFE (1210) may selectively transmit a transmission signal through a first antenna (1221) or a second antenna (1222) by an antenna switching module. Among the two transmission paths, the transmission or reception sensitivity may be degraded due to an external event (e.g., a grip event or a USB insertion event) for a specific transmission path. For example, if the RSRP (reference signal received power) of a signal received through the first antenna (1221) disposed at the bottom of the electronic device (101) is -125 dBm and the RSRP of a signal received through the second antenna (1222) disposed at the top of the electronic device (101) is -110 dBm, the electronic device (101) may determine that an imbalance has occurred. In the state where the above imbalance occurs, the electronic device (101) can operate in transmission sharing through the second antenna (1222) with relatively superior reception sensitivity since there is only one RFFE (1210) capable of processing low-band frequency signals. For example, the first signal corresponding to the first SIM and the second signal corresponding to the second SIM can operate in transmission sharing through the RFFE (1210) through the second antenna (1222).

[0128] FIG. 13 illustrates transmission of a transmission signal of an electronic device according to various embodiments.

[0129] Referring to FIG. 13, an electronic device according to various embodiments (e.g., electronic device (101) of FIG. 1A) may include a first RFFE (1311), a second RFFE (1312), a first antenna (1321), and a second antenna (1322).

[0130] According to various embodiments, the first RFFE (1311) and the second RFFE (1312) may process a mid-band frequency signal and a high-band frequency signal, respectively. The first RFFE (1311) may transmit a transmission signal through a first antenna (1321). The second RFFE (1312) may transmit a transmission signal through a second antenna (1322). For example, since the electronic device (101) includes two RFFEs that support a mid-band frequency signal and a high-band frequency signal, when the first signal corresponding to the first SIM and the second signal corresponding to the second SIM are a mid-band frequency signal or a high-band frequency signal, the first signal and the second signal may be set to full DSDA so that the first signal and the second signal may be transmitted simultaneously. For example, as illustrated in FIG. 13, a first signal corresponding to a first SIM may be transmitted through a second RFFE (1312) and a second antenna (1322), and at the same time, a second signal corresponding to a second SIM may be transmitted through a first RFFE (1311) and a first antenna (1321).

[0131] According to various embodiments, the transmission or reception sensitivity may be degraded for a specific transmission path among the two transmission paths due to an external event (e.g., a grip event or a USB insertion event). For example, if the reference signal received power (RSRP) of a signal received through the first antenna (1321) disposed at the bottom of the electronic device (101) is -125 dBm and the RSRP of a signal received through the second antenna (1322) disposed at the top of the electronic device (101) is -110 dBm, the electronic device (101) may determine that an imbalance has occurred. In a state where the imbalance has occurred, the electronic device (101) operates in full DSDA or full transmit simultaneous DSDA, so a second signal using the first antenna (1321) with relatively poor reception sensitivity may cause a radio link failure (RLF) or a random access channel (RACH) failure during RACH signal transmission. According to one embodiment, even when the above-described weak electric field conditions are not met, a phenomenon may occur in which the transmission power or current consumption increases due to relatively high path loss, or the throughput (TP) may decrease due to the inability to maintain a high modulation and coding scheme (MCS). For example, more problems may occur when operating in full DSDA or full transmit simultaneous DSDA for a mid-band frequency signal having relatively more transmission paths. In the embodiments described below, various embodiments that can solve the above-described problems by operating in transmission sharing according to set conditions in an electronic device (101) capable of operating in full DSDA or full transmit simultaneous DSDA will be described.

[0132] According to various embodiments, when a set condition is satisfied, even if the electronic device (101) supports full DSDA or full simultaneous transmission DSDA as illustrated in FIG. 13, it may be set to operate in transmission sharing. For example, in a condition where an imbalance occurs as described above, the electronic device (101) may operate in transmission sharing even though it can support full DSDA or full simultaneous transmission DSDA. In the state where the imbalance occurs, the electronic device (101) may alternately transmit a first signal corresponding to the first SIM and a second signal corresponding to the second SIM using the second antenna (1322) having a relatively good reception sensitivity and the second RFFE (1312) connected to the second antenna (1322).

[0133] In the above embodiment, a case in which an imbalance occurs has been described as an example of a condition in which the electronic device (101) operates by switching to transmission sharing in a situation in which the electronic device (101) supports full DSDA or full transmission simultaneous transmission DSDA. However, in the embodiments described below, embodiments including various conditions including a case in which the imbalance occurs will be described.

[0134] FIG. 14 illustrates a flowchart for explaining an operation method of an electronic device according to various embodiments.

[0135] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0136] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 1402, transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., the first RFFE (431)) at a first time point, and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., the second RFFE (432)). Simultaneously transmitting the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through the first RF circuit and the second RF circuit, respectively, may be referred to as full DSDA or full Tx concurrency DSDA, but the embodiments described below are not limited to the above terms. Additionally, in the embodiments described below, the full DSDA or full transmission concurrency DSDA may be referred to as a first transmission mode or a transmission concurrency mode related to DSDA (dual SIM dual active) performance, but is not limited to the above terms.

[0137] According to various embodiments, the electronic device (101) may, at a second time point, transmit a first signal corresponding to the first SIM through one RF circuit (e.g., the first RF circuit) selected from among the first RF circuit and the second RF circuit, based on determining that a first condition is satisfied in operation 1404. The electronic device (101) may, at a third time point, transmit a second signal corresponding to the second SIM through one RF circuit (e.g., the first RF circuit) selected from among the first RF circuit and the second RF circuit, based on determining that the first condition is satisfied in operation 1404 and operation 1406. For example, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit (e.g., the first RF circuit) selected from among the first RF circuit and the second RF circuit. Alternately transmitting a first signal corresponding to the first SIM and a second signal corresponding to the second SIM through one RF circuit (e.g., the first RF circuit) may be referred to as transmission sharing (or transmission time division), but the embodiments described below are not limited to the term. In addition, in the embodiments described below, the transmission sharing may be referred to as a second transmission mode or a transmission time division mode related to DSDA performance, but is not limited to the term. According to various embodiments, the electronic device (101) may operate by switching from the first transmission mode to the second transmission mode based on confirming that the first condition is satisfied.According to various embodiments, after switching to the second transmission mode, the electronic device (101) may operate by switching from the second transmission mode to the first transmission mode based on confirmation that the first condition is not satisfied.

[0138] According to various embodiments, the first condition may include at least one of the conditions described below. For example, the first condition may include that a difference between the intensity of a signal received through the first RF circuit and the intensity of a signal received through the second RF circuit exceeds a first threshold. The first condition may include that the first signal and the second signal are signals for data transmission. The first condition may include that the first signal and the second signal are signals for a voice call. A detailed description related to the first condition will be described later in the description of FIG. 15.

[0139] According to various embodiments, the electronic device (101) may perform the above-described operations 1404 and 1406 based on confirming that the first condition and / or the second condition are satisfied (e.g., based on confirming that the first condition is satisfied and the second condition is further satisfied). For example, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from the first RF circuit and the second RF circuit (e.g., the first RF circuit), based on confirming that the first condition is satisfied and the second condition described below is further satisfied.

[0140] According to various embodiments, the second condition may include at least one of the conditions described below. For example, the second condition may include that the intensity of the signal received through the first RF circuit or the intensity of the signal received through the second RF circuit is less than a second threshold. The second condition may include that the signal to noise ratio (SNR) of the signal received through the first RF circuit or the SNR of the signal received through the second RF circuit is less than a set threshold. The second condition may include that the modulation scheme of the first signal corresponding to the first SIM or the modulation scheme of the second signal corresponding to the second SIM is the lowest modulation scheme. The second condition may include that the block error rate (BLER) of the first signal corresponding to the first SIM or the BLER of the second signal corresponding to the second SIM exceeds a third threshold. The second condition may include that the first signal corresponding to the first SIM or the second signal corresponding to the second SIM is a signal corresponding to a RACH retry. The second condition may include that a scheduling time collision rate (or overlap rate) of the first signal corresponding to the first SIM and the second signal corresponding to the second SIM is less than a fourth threshold. The second condition may include that a scheduling ratio of the first signal corresponding to the first SIM or the second signal corresponding to the second SIM is less than a fifth threshold. A detailed description related to the second condition will be described later in the description of FIGS. 16 to 23.

[0141] According to various embodiments, the electronic device (101), based on verifying that the first condition and / or the second condition are satisfied in operations 1404 and 1406, may alternately transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through the first RF circuit and the second RF circuit, respectively, in a situation in which simultaneous transmission is possible (e.g., even in a situation in which simultaneous transmission is possible).

[0142] FIG. 15 illustrates a flowchart for explaining an operating method of an electronic device according to various embodiments.

[0143] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0144] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 1502, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0145] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on verifying that at least one condition (e.g., the conditions of operations 1504 and 1506) is satisfied. For example, when operating in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)).

[0146] For example, the electronic device (101) may determine whether the first signal and the second signal are a combination of different data types in operation 1504. For convenience of explanation, if the first signal is a signal for a voice call and the second signal is a signal for data communication, it will be expressed as “Voice++Data.” Various embodiments described below (e.g., embodiments disclosed in FIGS. 15 to 21) may be equally or similarly applied to the case where the first signal is a signal for a voice call and the second signal is a signal for data communication (“DATA++Voice”). As a result of the determination, if the first signal is a signal for a voice call and the second signal is a signal for data communication (e.g., “Voice++Data”) (operation 1504-Yes), the electronic device (101) may start operating with full DSDA or full transmit simultaneous DSDA, or maintain the operating full DSDA or full transmit simultaneous DSDA in operation 1510. For example, if either the first signal or the second signal is a signal for voice communication, full DSDA or full simultaneous transmission DSDA can be maintained so that a high-priority voice call can maintain a stable call state. For example, if the first signal is a signal for voice communication and the second signal is a signal for data communication, a stable call state can be maintained by transmitting the first signal through a relatively good transmission path (e.g., a transmission path corresponding to the first RF circuit). Since the second signal is transmitted through a relatively poor transmission path (e.g., a transmission path corresponding to the second RF circuit), a stable call state can be maintained even if an RLF occurs in the data communication.

[0147] According to various embodiments, if the determination result is that the first signal is not a signal for a voice call and the second signal is not a signal for data communication (e.g., "Voice++Voice" or "Data++Data") (operation 1504-No), the electronic device (101) may determine whether an imbalance has occurred in operation 1506. According to various embodiments, the electronic device may determine that an imbalance has occurred if a difference between the intensity of a signal received through the first RF circuit and the intensity of a signal received through the second RF circuit (hereinafter referred to as "imbalance" for convenience of explanation) exceeds a first threshold. The intensity of the received signal may include reference signal received power (RSRP). For example, the first threshold may be set to any value between about 5 and 10 dB, but is not limited to the above value.

[0148] According to various embodiments, if the determination result is that the imbalance exceeds the first threshold (Operation 1506 - Yes), the electronic device (101) may operate in transmission sharing mode in operation 1508. For example, as the electronic device (101) operates in transmission sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if the determination result is that the imbalance does not exceed the first threshold (Operation 1506 - No), the electronic device (101) may start operating in full DSDA or full transmit simultaneous DSDA mode in operation 1510, or maintain the operating full DSDA or full transmit simultaneous DSDA mode.

[0149] According to various embodiments, when both the first signal and the second signal are signals for voice communication (“Voice++Voice”) as described above, or when both the first signal and the second signal are signals for data communication (“Data++Data”), the electronic device (101) may alternately transmit the first signal and the second signal through an RF circuit having relatively good reception sensitivity by operating in transmission sharing.

[0150] According to various embodiments, operation 1504 or operation 1506 in FIG. 15 may be omitted. For example, the electronic device (101) may operate by determining only the condition of operation 1504 as the first condition described above, or by determining only the condition of operation 1506. According to various embodiments, the judgment order of operations 1504 and 1506 may be changed.

[0151] FIG. 16 illustrates a flowchart for explaining a method of operating an electronic device according to various embodiments.

[0152] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0153] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 1602, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0154] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on verifying that at least one condition (e.g., at least one condition of operation 1604, operation 1606, or operation 1608) is satisfied. For example, when operating in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)).

[0155] For example, the electronic device (101) may determine whether the first signal and the second signal are a combination of different data types in operation 1604. If, as a result of the determination in operation 1604, the first signal is a signal for a voice call and the second signal is a signal for data communication (e.g., “Voice++Data”) (operation 1604-Yes), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA in operation 1612, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0156] According to various embodiments, if the determination result of the operation 1604 is that the first signal is not a signal for a voice call and the second signal is not a signal for data communication (e.g., “Voice++Voice” or “Data++Data”) (operation 1604-No), the electronic device (101) may determine whether an imbalance has occurred in operation 1606. According to various embodiments, the electronic device may determine that an imbalance has occurred if the difference (e.g., imbalance) between the intensity of the signal received through the first RF circuit and the intensity of the signal received through the second RF circuit exceeds a first threshold value.

[0157] According to various embodiments, if the imbalance exceeds the first threshold as a result of the determination in operation 1606 (operation 1606-Yes), the electronic device (101) may determine whether the weak electric field condition is satisfied in operation 1608. Whether the weak electric field condition is satisfied may be confirmed through the RSRP or SNR (signal to noise ratio) of the signal received through the first RF circuit or the signal received through the second RF circuit. For example, if the RSRP of the signal received through the first RF circuit or the RSRP of the signal received through the second RF circuit is less than the second threshold (e.g., -120 dBm), it may be determined that the weak electric field condition is satisfied (e.g., in a weak electric field state). Alternatively, if the SNR for the signal received through the first RF circuit or the SNR for the signal received through the second RF circuit is less than a set threshold value (e.g., 0 dB), it may be determined that the weak electric field condition is satisfied (e.g., in a weak electric field state). According to various embodiments, if the determination result of the operation 1606 determines that the imbalance does not exceed the first threshold value (operation 1606-No), the electronic device (101) may, in operation 1612, start operation with a full DSDA or a full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0158] According to various embodiments, if it is determined as a result of the determination in operation 1608 that the weak electric field condition is satisfied (operation 1608-Yes), the electronic device (101) may operate in transmission sharing in operation 1610. For example, as the electronic device (101) operates in transmission sharing, it may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if it is determined as a result of the determination in operation 1608 that the weak electric field condition is not satisfied (operation 1608-No), the electronic device (101) may start operating in full DSDA or full transmit simultaneous transmission DSDA in operation 1612, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0159] According to various embodiments, even if both the first signal and the second signal are signals for voice calls (“Voice++Voice”) as described above, if the signal corresponding to a specific SIM is weak, the RLF or mute phenomenon can be reduced by switching to transmission sharing.

[0160] According to various embodiments, at least one of operations 1604, 1606, or 1608 in FIG. 16 may be omitted. For example, the electronic device (101) may determine only one of operations 1604 or 1606 as the first condition described above, and additionally determine the condition of operation 1608 as the second condition and operate. According to various embodiments, the judgment order of operations 1604, 1606, or 1608 may be changed.

[0161] FIG. 17 illustrates a flowchart for explaining an operation method of an electronic device according to various embodiments.

[0162] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0163] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 1702, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0164] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on verifying that at least one condition (e.g., at least one condition of operation 1704, operation 1706, operation 1708, or operation 1710) is satisfied. For example, when operating in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)).

[0165] For example, the electronic device (101) may determine whether the first signal and the second signal are a combination of different data types in operation 1704. If, as a result of the determination in operation 1704, the first signal is a signal for a voice call and the second signal is a signal for data communication (e.g., “Voice++Data”) (operation 1704-Yes), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA in operation 1714, or maintain the full DSDA or full transmit simultaneous transmission DSDA in operation.

[0166] According to various embodiments, if the determination result of the operation 1704 is that the first signal is not a signal for a voice call and the second signal is not a signal for data communication (e.g., “Voice++Voice” or “Data++Data”) (operation 1704-No), the electronic device (101) may determine whether an imbalance has occurred in operation 1706. According to various embodiments, the electronic device may determine that an imbalance has occurred if the difference (e.g., imbalance) between the intensity of the signal received through the first RF circuit and the intensity of the signal received through the second RF circuit exceeds a first threshold value.

[0167] According to various embodiments, if the determination result of operation 1706 indicates that the imbalance exceeds the first threshold (operation 1706 - Yes), the electronic device (101) may determine whether the weak electric field condition is satisfied in operation 1708. According to various embodiments, if the determination result of operation 1706 indicates that the imbalance does not exceed the first threshold (operation 1706 - No), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA in operation 1714, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0168] According to various embodiments, if it is determined as a result of the determination in operation 1708 that the weak electric field condition is satisfied (operation 1708-Yes), the electronic device (101) may determine whether the modulation type (or modulation scheme) satisfies the set condition in operation 1710. For example, if the modulation type is the lowest modulation type (e.g., quadrature phase shift keying (QPSK)), the electronic device (101) may determine that the modulation type satisfies the set condition. According to various embodiments, if it is determined as a result of the determination in operation 1710 that the modulation type satisfies the set condition (operation 1710-Yes), the electronic device (101) may operate in transmission sharing in operation 1712. For example, the electronic device (101) may, as it operates with the transmission sharing, alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if it is determined as a result of the determination in operation 1710 that the modulation method does not satisfy the set condition (operation 1710-No), the electronic device (101) may, in operation 1714, start operating with full DSDA or full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0169] According to various embodiments, the electronic device (101) may determine whether a block error rate (BLER) satisfies a set condition in addition to a modulation method in operation 1710. For example, the electronic device (101) may determine that the BLER satisfies the set condition when the BLER of the first signal corresponding to the first SIM or the BLER of the second signal corresponding to the second SIM exceeds a third threshold (e.g., 10%). According to various embodiments, when it is determined as a result of the determination in operation 1710 that the BLER satisfies the set condition (operation 1710-Yes), the electronic device (101) may operate in transmission sharing in operation 1712.

[0170] According to various embodiments, when the electronic device (101) is in a connected state, the modulation scheme is the lowest modulation scheme (e.g., QPSK), and the BLER of the transmission signal is above a certain level (e.g., 10% or more), there may be no way for the electronic device (101) to further reduce the BLER. Since the electronic device (101) is likely to experience RLF in the above state, the RLF can be prevented by operating in transmission sharing through a transmission path with relatively superior transmission performance.

[0171] FIG. 18 illustrates a flowchart for explaining an operation method of an electronic device according to various embodiments.

[0172] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0173] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 1802, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0174] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on confirming that at least one condition (e.g., at least one condition among operation 1804, operation 1806, operation 1808, or operation 1810) is satisfied. For example, when the electronic device (101) operates in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)). In FIG. 18, operations 1804, 1806, and 1808 are the same as or similar to operations 1704, 1706, and 1708 of FIG. 17, respectively, and thus detailed descriptions thereof will be omitted.

[0175] According to various embodiments, if it is determined as a result of the determination in operation 1808 that the weak electric field condition is satisfied (operation 1808-Yes), the electronic device (101) may determine in operation 1810 whether to perform a RACH retry as the transmission power of the RACH signal corresponds to the maximum transmission power. For example, if the electronic device (101) performs a RACH retry as the transmission power of the RACH signal corresponds to the maximum transmission power in operation 1810 (e.g., if the first signal or the second signal is a signal corresponding to the RACH retry) (operation 1810-Yes), the electronic device (101) may operate in transmission sharing in operation 1812. For example, the electronic device (101) may, as it operates with the transmission sharing, alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if the determination result of operation 1810 determines that RACH retry is not performed (operation 1810-No), the electronic device (101) may, in operation 1814, start operating with full DSDA or full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0176] According to various embodiments, when the electronic device (101) fails the RACH procedure despite transmitting the RACH signal at maximum power and performs a RACH retry, transmission sharing may be performed through an RF circuit corresponding to a transmission path with relatively superior transmission performance. For example, the electronic device (101) may succeed in the RACH by performing transmission sharing instead of full DSDA or full simultaneous transmission DSDA during a RACH retry following a RACH failure.

[0177] FIG. 19 illustrates a flowchart for explaining an operation method of an electronic device according to various embodiments.

[0178] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0179] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 1902, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0180] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on verifying that at least one condition (e.g., at least one condition of operation 1904, operation 1906, or operation 1908) is satisfied. For example, when operating in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)).

[0181] For example, the electronic device (101) may determine whether the first signal and the second signal are a combination of different data types in operation 1904. If, as a result of the determination in operation 1904, the first signal is a signal for a voice call and the second signal is a signal for data communication (e.g., “Voice++Data”) (operation 1904-Yes), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA in operation 1912, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0182] According to various embodiments, if the determination result of the operation 1904 is that the first signal is not a signal for a voice call and the second signal is not a signal for data communication (e.g., “Voice++Voice” or “Data++Data”) (operation 1904-No), the electronic device (101) may determine whether an imbalance has occurred in operation 1906. According to various embodiments, the electronic device may determine that an imbalance has occurred if the difference (e.g., imbalance) between the intensity of the signal received through the first RF circuit and the intensity of the signal received through the second RF circuit exceeds a first threshold value.

[0183] According to various embodiments, if the determination result of operation 1906 determines that the imbalance exceeds the first threshold (operation 1906-Yes), the electronic device (101) may determine whether the uplink scheduling conflict rate (UL scheduling time conflict rate) (or UL scheduling time conflict rate) satisfies a set condition in operation 1908. For example, the electronic device (101) may determine whether the conflict rate between the uplink scheduling of the first signal and the uplink scheduling of the second signal is less than a set threshold (e.g., a fourth threshold) in operation 1908. According to various embodiments, if the determination result of operation 1906 determines that the imbalance does not exceed the first threshold (operation 1906-No), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA in operation 1912.

[0184] According to various embodiments, if it is determined as a result of the determination in operation 1908 that the uplink scheduling collision rate satisfies the set condition (operation 1908-Yes) (e.g., if the uplink scheduling collision rate is less than the fourth threshold value), the electronic device (101) may operate in transmission sharing in operation 1910. For example, as the electronic device (101) operates in transmission sharing, it may alternately (or alternately) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if it is determined as a result of the determination in operation 1908 that the uplink scheduling collision rate does not satisfy the set condition (operation 1908-No) (e.g., if the uplink scheduling collision rate is equal to or greater than the fourth threshold value), the electronic device (101) may, in operation 1912, start operation with a full DSDA or a full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0185] According to various embodiments, the uplink scheduling information of the first signal and the uplink scheduling information of the second signal can be confirmed through a "UL Scheduling Report" message transmitted from each base station. For example, the electronic device (101) can confirm the transmission time of the first signal corresponding to the first SIM and the transmission time of the second signal corresponding to the second SIM through the "UL Scheduling Report" message transmitted from each base station. The electronic device (101) can confirm the ratio of overlapping scheduling times between the first signal and the second signal (scheduling collision rate) based on the transmission time of the first signal corresponding to the first SIM and the transmission time of the second signal corresponding to the second SIM. The electronic device (101) can determine whether to operate in transmission sharing based on the ratio of overlapping scheduling times. For example, the electronic device (101) can operate in transmission sharing when the confirmed scheduling collision rate is less than a fourth threshold value (e.g., 25%).

[0186] According to various embodiments, the fourth threshold value may use a fixed value or a dynamically changing value. For example, the fourth threshold value may be set to change according to the imbalance. As an example, when the electronic device (101) sets the first threshold value, which is the threshold for the imbalance in operation 1906, to 10 dB, the fourth threshold value, which is the threshold for the uplink scheduling collision rate, may be set to 25%. When the electronic device (101) sets the first threshold value to 15 dB, the fourth threshold value may be set to 35%. When the electronic device (101) sets the first threshold value to 20 dB, the fourth threshold value may be set to 40%. For example, since the larger the imbalance value, the throughput increase and the current consumption reduction effect may be relatively greater by operating in transmission sharing through an antenna with good transmission performance, the fourth threshold value may be set to increase as the first threshold value is set higher.

[0187] FIG. 20 illustrates a flowchart for explaining an operation method of an electronic device according to various embodiments.

[0188] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0189] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 2002, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0190] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on at least one condition (e.g., at least one condition of operation 2004, operation 2006, operation 2008, or operation 2010). For example, when operating in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)).

[0191] For example, the electronic device (101) may determine whether the first signal and the second signal are a combination of different data types in operation 2004. If, as a result of the determination in operation 2004, the first signal is a signal for a voice call and the second signal is a signal for data communication (e.g., “Voice++Data”) (operation 2004-Yes), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA in operation 2014, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0192] According to various embodiments, if the determination result of the operation 2004 is that the first signal is not a signal for a voice call and the second signal is not a signal for data communication (e.g., “Voice++Voice” or “Data++Data”) (operation 2004-No), the electronic device (101) may determine whether an imbalance has occurred in operation 2006. According to various embodiments, the electronic device may determine that an imbalance has occurred if the difference (e.g., imbalance) between the intensity of the signal received through the first RF circuit and the intensity of the signal received through the second RF circuit exceeds a first threshold value.

[0193] According to various embodiments, if the result of the determination in operation 2006 determines that the imbalance exceeds the first threshold value (operation 2006-Yes), the electronic device (101) may determine whether the weak electric field condition is satisfied in operation 2008. Whether the weak electric field condition is satisfied may be confirmed through the RSRP or SNR (signal to noise ratio) of the signal received through the first RF circuit or the signal received through the second RF circuit. For example, if the RSRP of the signal received through the first RF circuit or the RSRP of the signal received through the second RF circuit is less than the second threshold value (e.g., -120 dBm), it may be determined that the weak electric field condition is satisfied (e.g., in a weak electric field state). Alternatively, if the SNR for the signal received through the first RF circuit or the SNR for the signal received through the second RF circuit is less than a set threshold value (e.g., 0 dB), it may be determined that the weak electric field condition is satisfied (e.g., in a weak electric field state). According to various embodiments, if the determination result of the operation 2006 indicates that the imbalance does not exceed the first threshold value (operation 2006-No), the electronic device (101) may, in operation 2014, start operation with a full DSDA or a full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0194] According to various embodiments, if it is determined as a result of the determination in operation 2008 that the weak electric field condition is satisfied (operation 2008-Yes), the electronic device (101) may operate in transmission sharing in operation 2012. For example, as the electronic device (101) operates in transmission sharing, it may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater).

[0195] According to various embodiments, if it is determined in operation 2008 that the weak electric field condition is not satisfied (operation 2008-No), the electronic device (101) may determine in operation 2010 whether the uplink scheduling conflict rate (UL scheduling time conflict rate) (or uplink scheduling time conflict rate) satisfies the set condition. For example, the electronic device (101) may determine in operation 2010 whether the conflict rate between the uplink scheduling of the first signal and the uplink scheduling of the second signal is less than a set threshold value (e.g., a fourth threshold value).

[0196] According to various embodiments, if it is determined as a result of the determination in operation 2010 that the uplink scheduling collision rate satisfies the set condition (operation 2010-Yes) (e.g., if the uplink scheduling collision rate is less than the fourth threshold value), the electronic device (101) may operate in transmission sharing in operation 2012. For example, as the electronic device (101) operates in transmission sharing, it may alternately (or alternately) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if it is determined as a result of the determination in operation 2010 that the uplink scheduling collision rate does not satisfy the set condition (operation 2010-No) (e.g., if the uplink scheduling collision rate is equal to or greater than the fourth threshold value), the electronic device (101) may, in operation 2014, start operation with a full DSDA or a full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0197] According to various embodiments, according to the embodiment of FIG. 20, by adding a condition for comparing the uplink scheduling of the first signal and the uplink scheduling of the second signal to operate in transmission sharing, the throughput can be improved in a medium or strong electric field. For example, when the first SIM is a default data SIM (DDS) with an Internet packet data network (PDN) set as the default, the electronic device (101) can reduce power consumption or improve throughput by operating in transmission sharing by applying the conditions of FIG. 20 in a medium or strong electric field. For example, according to FIG. 20, the electronic device (101) can improve throughput in a medium or strong electric field, or reduce power consumption while maintaining throughput. According to various embodiments, when the scheduling times of the first signal corresponding to the first SIM and the second signal corresponding to the second SIM overlap by a certain level or more, operating in transmission sharing may result in a decrease in transmission frequency and a decrease in throughput. As described above, by operating in transmission sharing when the uplink scheduling collision rate of the first signal and the second signal in operation 2010 is less than the fourth threshold (e.g., 25%), the throughput can be improved or the consumption current can be reduced in a medium or strong field.

[0198] According to various embodiments, as illustrated in FIG. 20, when operating in transmission sharing based on the uplink scheduling collision rate, the first and second signals may be limited to the condition of "Data++Data." For example, when "Voice++Voice" is present, it may be more advantageous to set independent transmission paths for the first and second signals, even if the throughput is relatively low, unless the condition is weak.

[0199] FIG. 21 illustrates a flowchart for explaining a method of operating an electronic device according to various embodiments.

[0200] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0201] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 2102, operate in full DSDA (or full transmit simultaneous transmission DSDA) mode, or may determine that it is capable of operating in full DSDA or full transmit simultaneous transmission DSDA mode. For example, the electronic device (101) may transmit a first signal corresponding to a first SIM through a first RF circuit (e.g., a first RFFE (431)) and transmit a second signal corresponding to a second SIM through a second RF circuit (e.g., a second RFFE (432)) when operating in full DSDA or full transmit simultaneous transmission DSDA mode.

[0202] According to various embodiments, the electronic device (101) may operate in Tx Sharing based on verifying that at least one condition (e.g., at least one condition of operation 2104, operation 2106, or operation 2108) is satisfied. For example, when operating in Tx Sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., the first RF circuit (e.g., the first RFFE)).

[0203] For example, the electronic device (101) may determine whether the first signal and the second signal are a combination of different data types in operation 2104. If, as a result of the determination in operation 2104, the first signal is a signal for a voice call and the second signal is a signal for data communication (e.g., “Voice++Data”) (operation 1904-Yes), the electronic device (101) may start operation with full DSDA or full transmit simultaneous transmission DSDA in operation 2112, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0204] According to various embodiments, if the determination result of the operation 2104 is that the first signal is not a signal for a voice call and the second signal is not a signal for data communication (e.g., “Voice++Voice” or “Data++Data”) (operation 2104-No), the electronic device (101) may determine whether an imbalance has occurred in operation 2106. According to various embodiments, the electronic device may determine that an imbalance has occurred if the difference (e.g., imbalance) between the intensity of the signal received through the first RF circuit and the intensity of the signal received through the second RF circuit exceeds a first threshold value.

[0205] According to various embodiments, if the imbalance exceeds the first threshold as a result of the determination in operation 2106 (operation 2106-Yes), the electronic device (101) may determine, in operation 2108, whether the uplink scheduling rate (UL scheduling rate) of the first signal and the second signal satisfies a set condition. For example, the electronic device (101) may determine, in operation 2108, whether the uplink scheduling rate of the first signal and the uplink scheduling rate of the second signal are less than a set threshold (e.g., a fifth threshold). According to various embodiments, if the uplink scheduling ratio of the first signal and the uplink scheduling ratio of the second signal are equal to or greater than a set threshold value (e.g., a fifth threshold value) as a result of the determination in operation 2108 (operation 2108-No), the electronic device (101) may, in operation 2112, start operation with full DSDA or full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0206] According to various embodiments, if it is determined as a result of the determination in operation 2108 that the uplink scheduling ratio of the first signal or the second signal satisfies the set condition (operation 2108-Yes) (e.g., if the uplink scheduling ratio is less than the fifth threshold value), the electronic device (101) may operate in transmission sharing in operation 2110. For example, as the electronic device (101) operates in transmission sharing, the electronic device (101) may alternately (or in turn) transmit the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one RF circuit selected from among the first RF circuit and the second RF circuit (e.g., an RF circuit corresponding to a transmission path in which the strength of the received signal is relatively greater). According to various embodiments, if it is determined as a result of the determination in operation 2108 that the uplink scheduling ratio of the first signal or the second signal does not satisfy the set condition (operation 2108-No) (e.g., if the uplink scheduling ratio is equal to or greater than the fifth threshold value), the electronic device (101) may, in operation 2112, start operation with full DSDA or full transmit simultaneous transmission DSDA, or maintain the operating full DSDA or full transmit simultaneous transmission DSDA.

[0207] According to various embodiments, in the imbalanced state of operation 2106 as illustrated in FIG. 21, by adding a condition of operation 2108, the connection of the SIM using the transmission path in a better state can be guaranteed to the greatest extent possible. For example, if the scheduling ratio of the signal corresponding to the SIM using the transmission path with relatively better performance is less than a set value (e.g., a fifth threshold), transmission sharing can be operated. According to various embodiments, if the scheduling ratio of the signal corresponding to one SIM (e.g., the signal corresponding to the SIM using the relatively good transmission path) exceeds the set value, since there is relatively more data to be transmitted, the throughput may be reduced when transmission sharing is operated through the relatively better transmission path in the imbalanced state. According to various embodiments, in FIG. 21, transmission sharing can be operated only when the scheduling ratio of the signal corresponding to one SIM (e.g., the signal corresponding to the SIM using the relatively good transmission path) is less than a set value in the imbalanced state, thereby preventing a reduction in throughput.

[0208] Fig. 22 illustrates transmission of a transmission signal by an electronic device according to various embodiments. Fig. 23 illustrates transmission of a transmission signal by an electronic device according to various embodiments.

[0209] Referring to FIGS. 22 and 23, as described above, the electronic device (101) can operate by transmitting a first signal corresponding to the first SIM and a second signal corresponding to the second SIM based on confirmation that the set condition is satisfied.

[0210] According to various embodiments, the electronic device (101) may wait until there is no transmission data of the first signal corresponding to the currently connected first SIM before the timer expires when the second signal corresponding to the second SIM transmits a RACH signal for handover. For example, when the first signal corresponding to the first SIM and the second signal corresponding to the second SIM are transmitted in a transmission sharing manner, the electronic device (101) may wait for transmission until there is no transmission data of the signal corresponding to the SIM using a relatively better transmission path before the set timer expires in order to minimize damage to the signal corresponding to the SIM using a relatively better transmission path in an imbalanced state.

[0211] According to various embodiments, if there is time to transmit a second signal corresponding to a second SIM before the timer expires, as illustrated in FIG. 22, transmission of a second signal (e.g., a RACH signal) may be started in a free interval of a scheduling time of a first signal corresponding to the first SIM. According to various embodiments, as illustrated in FIG. 23, if there is no time margin until the timer expires, transmission of a second signal (e.g., a RACH signal) may be started even if the first signal corresponding to the first SIM is scheduled in order to prevent RLF of the second signal.

[0212] According to various embodiments, as described above with reference to FIGS. 15 to 21, the electronic device (101) may operate in transmission sharing even though it is capable of operating in full DSDA or full transmission simultaneous transmission DSDA when a set condition is satisfied while operating in full DSDA or full transmission simultaneous transmission DSDA. According to various embodiments, the electronic device (101) operating in transmission sharing may return to operating in full DSDA or full transmission simultaneous transmission DSDA when any one of the first conditions is not satisfied. For example, the electronic device (101) operating in transmission sharing may maintain the operation in transmission sharing when the RSRP or SNR for the first signal corresponding to the first SIM or the second signal corresponding to the second SIM does not improve to a set value (e.g., a second threshold) or more. The electronic device (101) operating in the transmission sharing mode may return to full DSDA or full transmission simultaneous transmission DSDA and operate when the RSRP or SNR for the first signal corresponding to the first SIM or the second signal corresponding to the second SIM improves to a set value (e.g., a second threshold) or more, or when the imbalance drops below a set value (e.g., the first threshold). According to various embodiments, the threshold values ​​for the electronic device (101) operating in the transmission sharing mode to operate in full DSDA may be set differently from the threshold values ​​(e.g., the first threshold value to the fifth threshold value) set for operating in the transmission sharing mode through a hysteresis algorithm to prevent a ping-pong phenomenon.

The above instructions may cause switching from the first transmission mode to the second transmission mode by alternately transmitting the first signal corresponding to the first SIM and the second signal corresponding to the second SIM through one of the first RF circuit and the second RF circuit, based on verifying that the first condition is satisfied.

[0214] According to one embodiment, the first transmission mode may correspond to a transmission concurrency mode associated with dual SIM dual active (DSDA) performance, and the second transmission mode may correspond to a transmission sharing mode associated with DSDA performance.
