[0002] With the recent advancement of mobile communication technology and the widespread use of mobile terminals with various functions, efforts are being made to develop 5G communication systems to meet the increasing demand for wireless data traffic. To achieve high data transmission rates and provide faster data transmission speeds, 5G communication systems are being considered for implementation in higher frequency operating bands (e.g., bands above 6 GHz) in addition to the operating bands (in other words, frequency bands) (e.g., bands below 6 GHz) used in 3G and LTE (long term evolution) communication systems. The problem to be solved

[0003] The electronic device may support EN-DC (E-UTRA new radio dual connectivity), which uses both an LTE communication system and a 5G communication system to provide faster data transmission speeds. When the electronic device operates in EN-DC mode, a 2TX operation may be performed to transmit RF signals in multiple operating bands (e.g., an E-UTRA (evolved universal terrestrial radio access) operating band and an NR (new radio) operating band). During the process of transmitting RF signals in multiple operating bands, intermodulation distortion (IMD) (hereinafter IMD) may occur in at least one communication component (e.g., RFFE (radio frequency front end)) included in the electronic device. If such an IMD component is included in the downlink band, a degradation of RX performance (e.g., desensitization) of the received RF signal may occur.

[0004] The electronic device may support carrier aggregation (e.g., uplink carrier aggregation (ULCA)) using an LTE communication system in multiple operating bands to provide faster data transmission speeds. When the electronic device operates as a CA (e.g., ULCA), a 2TX operation of transmitting RF signals in multiple operating bands may be performed. Even in this case, IMD may occur in at least one communication component (e.g., RFIC (in other words, transceiver) and / or RFFE), and degradation of RX performance (e.g., sensitivity degradation) for the received RF signal may occur.

[0005] Meanwhile, in addition to the aforementioned EN-DC, the electronic device may support NE-DC (new radio E-UTRA dual connectivity), MR-DC (multi-RAT dual connectivity) and / or NR-DC (new radio dual connectivity) using two or more RATs (radio access technologies), and even in this case, IMD may occur in at least one communication component (e.g., RFIC and / or RFFE), resulting in degradation of RX performance (e.g., sensitivity degradation) for the received RF signal.

[0006] According to various embodiments, an electronic device and a method for controlling the same may be provided for adjusting the gain of at least one amplification element (e.g., LNA (low noise amplifier)) included in at least one communication component (e.g., RFIC and / or RFFE) during 2TX operation. means of solving the problem

[0008] According to various embodiments, a method for controlling an electronic device comprises: controlling the RFIC to set the gain of at least one first LNA among a plurality of first LNAs included in the RFIC to a first gain for processing a second RF signal of a first downlink band of a first operating band provided from the RFFE of the electronic device to the RFIC, based on the output of a first RF signal of a first uplink band of a first operating band through the RFIC of the electronic device; and controlling the RFIC to set the gain of the at least one first LNA for processing the second RF signal provided from the at least one RFFE to the RFIC to a second gain, based on the output of at least the first RF signal and a third RF signal of a second uplink band of a second operating band different from the first operating band through the RFIC at least simultaneously, wherein the second gain may be smaller than the first gain.

[0009] According to various embodiments, a computer-readable non-volatile recording medium stores instructions such that, when executed, at least one communication processor of an electronic device controls the RFIC to set the gain of at least one first LNA included in the RFIC to a first gain for processing a second RF signal of a first downlink band of a first operating band provided from the RFFE of the electronic device to the RFIC based on the output of a first RF signal of a first uplink band of a first operating band through the RFIC of the electronic device, and controls the RFIC to set the gain of at least one first LNA for processing a second RF signal provided from the at least one RFFE to the RFIC to a second gain based on the output of at least simultaneously the first RF signal and a third RF signal of a second uplink band of a second operating band different from the first operating band through the RFIC, and the second gain may be smaller than the first gain.

For example, as shown in FIG. 2b, the integrated communication processor (260) may support functions for communication with both the first cellular network (292) and the second cellular network (294).

[0042] According to one embodiment, the wireless communication module (192) may further include memory (not shown) (e.g., random access memory (RAM)). When the electronic device (101) is booted (e.g., after booting), information stored in the processor (120) (e.g., application processor) may be updated in the memory (not shown) (e.g., RAM) of the wireless communication module (192). For example, the information updated in the memory (not shown) of the wireless communication module (192) may include information used when at least one communication processor (e.g., first communication processor (212), second communication processor (214) and / or integrated communication processor (260)) controls at least one RFIC (222, 224, 228) and / or at least one RFFE (232, 234). For example, information updated in the memory (not shown) of the wireless communication module (192) may include information (e.g., a look-up table) about the gain (or gain mode) of at least one RFIC (222, 224, 228) and / or at least one RFFE (232, 234).

[0043] The first RFIC (222) can convert a baseband signal generated by the first communication processor (212) during transmission into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network (292) (e.g., legacy network). During reception, the RF signal is acquired from the first cellular network (292) (e.g., legacy network) through an antenna (e.g., first antenna module (242)) and can be preprocessed through an RFFE (e.g., first RFFE (232)). The first RFIC (222) can convert the preprocessed RF signal into a baseband signal so that it can be processed by the first communication processor (212).

[0044] The second RFIC (224) can convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) during transmission into an RF signal of the Sub6 band (e.g., about 6 GHz or lower) used in the second cellular network (294) (e.g., 5G network) (hereinafter, 5G Sub6 RF signal). During reception, the 5G Sub6 RF signal is acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., the second antenna module (244)) and can be preprocessed through an RFFE (e.g., the second RFFE (234)). The second RFIC (224) can convert the preprocessed 5G Sub6 RF signal into a baseband signal so that it can be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0045] The third RFIC (226) can convert a baseband signal generated by the second communication processor (214) into an RF signal of the 5G Above6 band (e.g., approximately 6 GHz to approximately 60 GHz) (hereinafter, 5G Above6 RF signal) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal may 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) may be formed as part of the third RFIC (226).

[0046] According to one embodiment, the electronic device (101) may include a fourth RFIC (228) separately from or at least as 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) in 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) through 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.

[0047] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as at least part of a single chip or a single package. According to various embodiments, if the first RFIC (222) and the second RFIC (224) in FIG. 2a or FIG. 2b are implemented as a single chip or a single package, the second RFIC (224) may be omitted. In this case, the first RFIC (222) may be connected to the first RFFE (232) and the second RFFE (234) so ​​that the first RFIC (222) converts a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmits the converted signal to either the first RFFE (232) or the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as a single chip or as at least part of a single package. According to one embodiment, at least one of 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 plurality of corresponding bands.

[0048] According to one embodiment, the third RFIC (226) and the antenna (248) may be placed on the same substrate to form a third antenna module (246). For example, a wireless communication module (192) or a processor (120) may be placed on the first substrate (e.g., main PCB). In this case, the third RFIC (226) may be placed on a portion of a second substrate (e.g., sub PCB) separate from the first substrate (e.g., bottom surface), and the antenna (248) may be placed on another portion of a second substrate (e.g., top surface) to form the third antenna module (246). By placing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line between them. This can reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., about 6 GHz to about 60 GHz) used for 5G network communication by the transmission line. As a result, the electronic device (101) can improve the quality or speed of communication with the second cellular network (294) (e.g., 5G network).

[0049] According to one embodiment, the antenna (248) may be formed as an antenna array comprising a plurality of antenna elements that can be used for beamforming. In this case, the third RFIC (226) may include, for example, a plurality of phase shifters (238) corresponding to the plurality of antenna elements as part of the third RFFE (236). During transmission, the plurality of phase shifters (238) may change the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device (101) (e.g., a base station (BS) of a 5G network) through their respective corresponding antenna elements. During reception, the plurality of phase shifters (238) may change the phase of a 5G Above6 RF signal received from the outside through their respective corresponding antenna elements to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the outside.

[0050] The second cellular network (294) (e.g., 5G network) may be operated independently of the first cellular network (292) (e.g., legacy network) (e.g., Stand-Alone (SA)) or connected (e.g., Non-Stand Alone (NSA)). For example, the 5G network may only have an access network (e.g., 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) can access the access network of the 5G network and then access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., evolved packed core (EPC)). Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., NR protocol information) is stored in memory (230) and can be accessed by other parts (e.g., processor (120), first communication processor (212), and / or second communication processor (214)).

[0051] FIG. 3a is a drawing illustrating wireless communication systems providing legacy network communication and / or 5G network communication according to various embodiments. FIG. 3b is a drawing illustrating wireless communication systems providing legacy network communication and / or 5G network communication according to various embodiments. FIG. 3c is a drawing illustrating wireless communication systems providing legacy network communication and / or 5G network communication according to various embodiments.

[0052] Referring to FIGS. 3a, 3b, and 3c, network environments (300a to 300c) may include at least one of a legacy network and a 5G network. The legacy network may include, for example, an LTE (or 4G) base station (340) of the 3GPP standard that supports wireless access with an electronic device (101) (e.g., eNB(eNodeB)) and an EPC (evolved packet core) (342) that manages 4G communication. The 5G network may include, for example, a New Radio (NR) base station (350) that supports wireless access with an electronic device (101) (e.g., gNB(gNodeB)) and a 5GC (5th generation core) (352) that manages 5G communication of the electronic device (101).

[0053] According to various embodiments, the electronic device (101) may transmit and receive control messages and user data via legacy communication and / or 5G communication. The control message may include, for example, a message related to at least one of security control, bearer setup, authentication, registration, or mobility management of the electronic device (101). The user data may refer to user data excluding control messages transmitted and received between the electronic device (101) and the core network (330) (e.g., EPC (342)).

[0054] Referring to FIG. 3a, an electronic device (101) according to one embodiment can transmit and receive at least one of control messages or user data with at least a part of a 5G network (e.g., an NR base station (350) and / or a 5GC (352)) using at least a part of a legacy network (e.g., an LTE base station (340) and / or an EPC (342)).

[0055] According to various embodiments, the network environment (300a) may include a network environment that provides wireless communication dual connectivity (DC) to an LTE base station (340) and an NR base station (350), and transmits and receives control messages to and from an electronic device (101) through a core network (330) of either an EPC (342) or a 5GC (352).

[0056] According to various embodiments, in a dual connectivity (DC) environment, one of the LTE base stations (340) or NR base stations (350) may operate as a master node (MN) (310) and the other as a secondary node (SN) (320). The MN (310) may be connected to a core network (230) to transmit and receive control messages. The MN (310) and the SN (320) may be connected via a network interface to transmit and receive messages related to the management of wireless resources (e.g., communication channels) to each other.

[0057] According to various embodiments, the MN (310) may be composed of an LTE base station (340), the SN (320) of an NR base station (350), and the core network (330) of an EPC (342). For example, control messages may be transmitted and received through the LTE base station (340) and the EPC (342), and user data may be transmitted and received through at least one of the LTE base station (340) or the NR base station (350).

[0058] According to various embodiments, the MN (310) may be composed of an NR base station (350), the SN (320) of an LTE base station (340), and the core network (330) of a 5GC (352). For example, control messages may be transmitted and received through the NR base station (350) and the 5GC (352), and user data may be transmitted and received through at least one of the LTE base station (340) or the NR base station (350).

[0059] Referring to FIG. 3b, according to various embodiments, a 5G network may be composed of an NR base station (350) and a 5GC (352), and may transmit and receive control messages and user data independently of an electronic device (101).

[0060] Referring to FIG. 3c, according to various embodiments, the legacy network and the 5G network may each provide data transmission and reception independently. For example, the electronic device (101) and the EPC (342) may transmit and receive control messages and user data through an LTE base station (340). In another example, the electronic device (101) and the 5GC (352) may transmit and receive control messages and user data through an NR base station (350).

[0061] According to various embodiments, the electronic device (101) can be registered with at least one of the EPC (342) or 5GC (352) to send and receive control messages.

[0062] According to various embodiments, the EPC (342) or 5GC (352) may interwork to manage the communication of the electronic device (101). For example, movement information of the electronic device (101) may be transmitted and received through an interface between the EPC (342) and 5GC (352).

[0063] As described above, dual connectivity (DC) through the LTE base station (340) and NR base station (350) may be called EN-DC.

[0064] Operations according to various embodiments will be described with reference to the drawings below. In the embodiments described below, the description is based on the premise that the LTE base station (340) is connected to the MN (310), the NR base station (350) to the SN (320), and the electronic device (101) is connected to the first cellular network (292) (e.g., legacy network) and the second cellular network (294) (e.g., 5G network). However, the embodiments described below may also be applied when the electronic device (101) supports various forms of dual connectivity (DC) (e.g., NE-DC and / or MR-DC). In this case, in the embodiments described below, 'first network' and 'second network' may refer to the first cellular network (292) and the second cellular network (294). Additionally, the embodiments described below may also be applied when the electronic device (101) supports connectivity using a single RAT (e.g., Carrier Aggregation (CA)) rather than dual connectivity using two or more RATs. In this case, in the embodiments described below, 'first network' and 'second network' may refer to the first cellular network (292).

[0065] FIG. 4 is a drawing for illustrating examples of IMD occurring according to various embodiments.

[0066] According to various embodiments, an electronic device (e.g., the electronic device (101) of FIG. 1) may be connected to a first cellular network (e.g., the first cellular network (292) of FIG. 2a and / or FIG. 2b) and a second cellular network (e.g., the second cellular network (294) of FIG. 2a and / or FIG. 2b). According to various embodiments, the electronic device (101) may transmit and / or receive RF signals of a first operating band corresponding to the first cellular network (292), and transmit and / or receive RF signals of a second operating band corresponding to the second cellular network (294) which is different from the first operating band.

[0067] Referring to FIG. 4, an example is illustrated in which the first operating band is B1 of an LTE communication network (or RAT of E-UTRA) and the second operating band is N3 of a 5G communication network (or RAT of NR). In this case, the first operating band ("B1") may include a first uplink band (e.g., an uplink band with a frequency band of 1925 to 1935 Hz ("B1 TX")) and a first downlink band (e.g., a downlink band with a frequency band of 2115 to 2125 Hz ("B1 RX")). The second operating band ("N3") may include a second uplink band (e.g., an uplink band with a frequency band of 1725 to 1735 Hz ("N3 TX")) and a second downlink band (e.g., a downlink band with a frequency band of 1820 to 1830 MHz ("N3 RX")).

[0068] According to various embodiments, the electronic device (101) may operate as 2TX to generate and / or transmit (e.g., to an antenna) RF signals of a plurality of operating bands (e.g., a first uplink band and a second uplink band) at least simultaneously. In this process, an IMD component may be generated by the RF signal of the first uplink band and the RF signal of the second uplink band, and the generated IMD component (e.g., a third-order IMD (IMD3) component) may affect at least one downlink band of the electronic device (101). For example, the frequency of the generated IMD component (e.g., IMD3) may be expressed as 2f1-f2 and / or 2f2-f1 based on at least one frequency ("f1") of the first uplink band (hereinafter, at least one first frequency) and at least one frequency ("f2") of the second uplink band (hereinafter, at least one second frequency). If, as described, the frequency (e.g., 2f1-f2 and / or 2f2-f1) of the generated IMD component (e.g., IMD3) falls within the frequency range of the first downlink band and / or the second downlink band, then RX performance degradation (e.g., sensitivity degradation) for the RF signal of the first downlink band and / or the second downlink band received by the electronic device (101) may occur.

[0069] Although FIG. 4 illustrates the case where the first and second operating bands are B1 and N3, the same can be described for operating bands in which at least one frequency of a plurality of uplink bands is included in at least one downlink band. Furthermore, while FIG. 4 describes examples of MR-DC for the E-UTRA band and NR band, those skilled in the art will understand that, as described above, the same can be applied to bands corresponding to each of the plurality of CCs (component carriers) by CA in a single RAT.

[0070] FIG. 5 is a block diagram illustrating communication components of an electronic device (101) according to various embodiments. Hereinafter, the description will be made with reference to FIG. 2a and / or FIG. 2b.

[0071] According to various embodiments, the electronic device (101) may include an RFIC (501) (e.g., a first RFIC (222) and / or a second RFIC (224) of FIG. 2a and / or FIG. 2b), a first PA (power amplifier) ​​(503a), a second PA (503b), a first LNA (505a), a second LNA (505b), a first switch (507) (e.g., a PA band selection switch), a first filter (509a), a second filter (509a) and / or a second switch (511) (e.g., an antenna switch).

[0072] According to various embodiments, the RFIC (501) may include a first RFIC (222) operably connected to a first communication processor (212) (or an integrated communication processor (260)) and a first PA (503a), and a second RFIC (224) operably connected to a second communication processor (214) (or an integrated communication processor (260)) and a second PA (503b). According to various embodiments, the RFIC (501) may include at least one amplification element (e.g., a PA and / or an LNA), and the components included in the RFIC (501) will be described in more detail through the drawings described below. According to various embodiments, the first PA (503a), the first LNA (505a), and the first filter (509a) may constitute the first RFFE (232), and the second PA (503b), the second LNA (505b), and the second filter (509b) may constitute the second RFFE (234). Meanwhile, as described above, various embodiments may be applied to CA as well as MR-DC, in which case the first PA (503a), the first LNA (505a), the first filter (509a), the second PA (503b), the second LNA (505b), and the second filter (509b) may be implemented as at least one RFFE for one RAT. At least one RFFE may be configured in the form of a PAM (power amplifier module), a FEM (front end module), a PAMiD (power amplifier module including duplexer), an LPAMID (LNA and PAM with integrated duplexer or diplexer) and / or an LPAMIF (PA with integrated low noise amplifier and filter), and there are no restrictions on the form of implementation.

[0073] According to various embodiments, the RFIC (501) can convert a baseband signal generated by at least one communication processor (e.g., first communication processor (212), second communication processor (214) and / or integrated communication processor (260)) into a radio frequency (RF) signal used in a first network (e.g., first cellular network (292)) or a second network (e.g., second cellular network (294)). For example, the RFIC (501) (e.g., first RFIC (222)) can provide the RF signal used in the first network to a first RFFE (232) (e.g., first PA (503a)). The RFIC (501) (e.g., second RFIC (224)) can provide the RF signal used in the second network to a second RFFE (234) (e.g., second PA (503b)). According to various embodiments, the RFIC (501) can convert an RF signal received from at least one RFFE (e.g., a first RFFE (232) or a second RFFE (234)) into a baseband signal upon reception and provide it to at least one communication processor (e.g., a first communication processor (212), a second communication processor (214) and / or an integrated communication processor (260)).

[0074] According to various embodiments, the first PA (503a) and the second PA (503b) can amplify an RF signal input from the RFIC (501) (e.g., an RF signal in the uplink band) and output it to the first switch (507).

[0075] According to various embodiments, the first filter (509a) and the second filter (509b) can filter an RF signal (e.g., an RF signal in the uplink band) input through the first switch (507) in a specified range of frequency bands. According to various embodiments, the RF signal filtered by the first filter (509a) and / or the second filter (509b) can be output externally through at least one antenna ("Ant 1" and / or "Ant 2") (e.g., the first antenna module (242) and / or the second antenna module (244)). According to various embodiments, the first filter (509a) and the second filter (509b) can filter an RF signal (e.g., an RF signal in the downlink band) input through the second switch (511) in a specified range of frequency bands. According to various embodiments, an RF signal filtered by a first filter (509a) and / or a second filter (509b) can be input to at least one LNA (e.g., a first LNA (505a) and / or a second LNA (505b)).

[0076] According to various embodiments, the first LNA (505a) and the second LNA (505b) can amplify an RF signal (e.g., an RF signal in the downlink band) input from at least one filter (e.g., the first filter (509a) and / or the second filter (509b)) and output it to the RFIC (501).

[0077] Referring to FIG. 5, an IMD component may be generated in at least one of the communication components described above by RF signals generated by the RFIC (501). For example, the RFIC (501) may provide a first RF signal of frequency f1 and a second RF signal of frequency f2 to the first PA (503a) and the second PA (503b). The first RF signal input to the first PA (503a) may be induced into the input path of the second PA (503b), or the second RF signal input to the second PA (503b) may be induced into the input path of the first PA (503a), thereby generating an IMD component in the first PA (503a) and / or the second PA (503b). For example, a first RF signal amplified by the first PA (503a) may be induced into the input path of the second PA (503b), or a second RF signal amplified by the second PA (503b) may be induced into the input path of the first PA (503a), so that an IMD component may be generated in the first PA (503a) and / or the second PA (503b). For example, a first RF signal amplified by the first PA (503a) may be induced into the path connecting the second PA (503b) and the first switch (507), or a second RF signal amplified by the second PA (503b) may be induced into the path connecting the first PA (503a) and the first switch (507), so that an IMD component may be generated in the first switch (507). For example, a first RF signal input to the first filter (509a) through the first switch (507) may be induced into the input path of the second filter (509b), or a second RF signal input to the second filter (509b) through the first switch (507) may be induced into the input path of the first filter (509a), so that an IMD component may be generated in the first filter (509a) and / or the second filter (509b).For example, a first RF signal input to the second filter (511) through the first filter (509a) may be induced into a path connecting the second filter (509b) and the second switch (511), or a second RF signal input to the second switch (511) through the second filter (509b) may be induced into a path connecting the first filter (509a) and the second switch (511), so that an IMD component may be generated at the second switch (511). For example, a first RF signal input to the first antenna ("Ant 1") (e.g., the first antenna module (242)) through the second switch (511) may be induced to the second antenna ("Ant 2") (e.g., the second antenna module (244)), or a second RF signal input to the second antenna ("Ant 2") (e.g., the second antenna module (244)) through the second switch (511) may be induced to the first antenna ("Ant 1") (e.g., the first antenna module (242)), so that an IMD component may be generated in the first antenna ("Ant 1") and / or the second antenna ("Ant 2"). For example, a first RF signal and / or a second RF signal may be induced into the input path of a first LNA (505a) and / or a second LNA (505b), and an IMD component may be generated in the first LNA (505a) and / or the second LNA (505b) by the induced RF signal and an RF signal received from the outside through the first antenna ("Ant 1") and / or the second antenna ("Ant 2") (e.g., a third RF signal at frequency f3 and / or a fourth RF signal at frequency f4). For example, an RF signal output from either the first LNA (505a) or the second LNA (505b) may be induced into the input path and / or output path of the other LNA, and an IMD component may be generated in the first LNA (505a), the second LNA (505b), and / or the RFIC (501).

[0078] If the above-described IMD components are included in the downlink band of the electronic device (101), RX performance degradation (e.g., sensitivity degradation) for RF signals received from the outside may occur. For example, when the isolation (e.g., DPX isolation) characteristic of the first and second filters (509a, 509b) is 60dB, the IIP3 characteristic of the RFIC (501) is 0dBm, the IIP3 characteristic of the first and second LNAs (505a, 505b) is -5dBm, the gain of the first and second LNAs (505a, 505b) is 19dB, and the default sensitivity is -100dBm, if the above-described IMD components occur, the sensitivity may be -86dBm, resulting in a sensitivity degradation of 14dB. If the first and second filters (509a, 509b) can be implemented with isolation characteristics of 60 dB or more, sensitivity degradation may be reduced, but there are limits to the isolation characteristics that can be implemented, and it may be difficult to guarantee for all RX frequencies.

[0079] FIG. 6a is a block diagram illustrating the components of an RFIC (501) according to various embodiments. FIG. 6b is a diagram illustrating a method for an electronic device (e.g., the electronic device (101) of FIG. 1) to control the LNA gain of the RFIC (501) according to various embodiments. Hereinafter, the description will be made with reference to FIG. 2a, FIG. 2b and / or FIG. 5 together.

[0080] Referring to FIG. 6a, according to various embodiments, the RFIC (501) may include an LNA (601), a mixer (603), a voltage-controlled oscillator (VCO) (605), a baseband filter (607), and / or an analog-digital converter (ADC) (607). According to various embodiments, the LNA (601), the mixer (603), the voltage-controlled oscillator (VCO) (605), the baseband filter (607), and / or an analog-digital converter (ADC) (607) may be included in the first RFIC (222) and the second RFIC (224), respectively.

[0081] According to various embodiments, the LNA (601) can amplify RF signals input from the LNA (e.g., the first LNA (505a) or the second LNA (505b)) of the RFFE (e.g., the first RFFE (232) or the second RFFE (234)) and output them to the mixer (603). According to various embodiments, the mixer (603) can convert the RF signal input from the LNA (601) into a baseband signal based on the frequency of the signal input from the VCO (605). According to various embodiments, the baseband filter (607) can filter the baseband signal converted by the mixer (603) in a specified range of frequency bands (e.g., a band below a specified frequency). According to various embodiments, the ADC (609) can convert a baseband signal filtered by a baseband filter (607) into a digital signal and provide it to at least one communication processor (e.g., a first communication processor (212), a second communication processor (214) and / or an integrated communication processor (260)).

[0082] According to various embodiments, the gain of the LNA (601) may be controlled by at least one communication processor (e.g., a first communication processor (212), a second communication processor (214), and / or an integrated communication processor (260)). For example, the gain of the LNA (601) may be changed based on a control signal input to the RFIC (501) from at least one communication processor (e.g., a first communication processor (212), a second communication processor (214), and / or an integrated communication processor (260)).

[0083] Referring to FIG. 6b, gain modes of an RFIC (501) (e.g., LNA (601)) are illustrated. According to various embodiments, the gain of the RFIC (501) (e.g., LNA (601)) may decrease as the gain mode changes from G0 mode to G3 mode, and may increase as the gain mode changes from G3 mode to G0 mode. In the graph of FIG. 6b, the X-axis represents the magnitude of the received electric field (cell power) (e.g., intensity of the RF signal in the downlink band) [dBm], and the direction of +X may indicate a lower received electric field (e.g., a larger absolute value of the received electric field [dBm]).

[0084] According to various embodiments, an electronic device (101) (e.g., a first communication processor (212), a second communication processor (214) and / or an integrated communication processor (260)) can control the gain of an RFIC (501) (e.g., an LNA (601)) based on a received cell power (e.g., the intensity of an RF signal in a downlink band). For example, the electronic device (101) can control the gain of the RFIC (501) (e.g., an LNA (601)) in a hysteresis manner based on the received cell power. For example, hysteresis control can be performed based on information (e.g., a look-up table) stored in a memory (not shown) of a wireless communication module (e.g., the wireless communication module (192) of FIG. 2a and / or FIG. 2b).

[0085] Referring to FIG. 6b, the electronic device (101) has a received electric field P C1 P below (e.g., -58dBm) C1 When increasing (①), the RFIC (501) (e.g., LNA (601)) can be controlled so that the gain mode of the RFIC (501) (e.g., LNA (601)) changes from G2 mode to G3 mode (e.g., the gain of the RFIC (501) (e.g., LNA (601)) decreases). The electronic device (101) is such that the received electric field is P C2 P at (e.g., -60dBm) or higher C2 When reduced to (②), the RFIC (501) (e.g., LNA (601)) can be controlled so that the gain mode of the RFIC (501) (e.g., LNA (601)) changes from G3 mode to G2 mode (e.g., the gain of the RFIC (501) (e.g., LNA (601)) increases). The electronic device (101) is such that the received electric field is P C3 P below (e.g., -68dBm) C3When increasing to (③), the RFIC (501) (e.g., LNA (601)) can be controlled so that the gain mode of the RFIC (501) (e.g., LNA (601)) changes from G1 mode to G2 mode (e.g., the gain of the RFIC (501) (e.g., LNA (601)) decreases). The electronic device (101) is such that the received electric field is P C4 P at (e.g., -70dBm) or higher C4 When reduced to (④), the RFIC (501) (e.g., LNA (601)) can be controlled so that the gain mode of the RFIC (501) (e.g., LNA (601)) changes from G2 mode to G1 mode (e.g., the gain of the RFIC (501) (e.g., LNA (601)) increases). The electronic device (101) is such that the received electric field is P C5 P below (e.g., -78dBm) C5 When increasing (⑤), the RFIC (501) can be controlled so that the gain mode of the RFIC (501) (e.g., LNA (601)) changes from G0 mode to G1 mode (e.g., the gain of the RFIC (501) (e.g., LNA (601)) decreases). The electronic device (101) is such that the received electric field is P C6 P at (e.g., -80dBm) or higher C6 When decreasing (⑥), the RFIC (501) (e.g., LNA (601)) can be controlled so that the gain mode of the RFIC (501) (e.g., LNA (601)) changes from G1 mode to G0 mode (e.g., the gain of the RFIC (501) (e.g., LNA (601)) increases).

[0086] According to various embodiments, the electronic device (101) can control the RFIC (501) so that the gain of the RFIC (501) (e.g., LNA (601)) is reduced when the RF signal of the first uplink band of the first operating band and the RF signal of the second uplink band of the second operating band are output from the RFIC (501) to the RFFE (e.g., first RFFE (232) and second RFFE (234)) at least simultaneously (e.g., 2TX operation is performed), and will be described in more detail through the drawings described below.

[0087] Meanwhile, if the gain of the RFIC (501) (e.g., LNA (601)) is reduced, the IIP3 characteristics of the RFIC (501) are improved (e.g., the absolute value of the IIP3 value increases), and the degradation of RX performance (e.g., sensitivity degradation) can be reduced.

[0088] RFIC gain mode G0 G1 G2 G3 RFIC IIP3[dBm] 0 -4 -5 -7 RFIC NF[dB] 13.5 14 14 19 Desense[dB] 14 6.85 5.38 3.03 Default Sensitivity[dBm] -100 -99.9 -99.9 -98.5

[0089] Referring to Table 1, as the gain of RFIC (501) decreases (e.g., G0 mode → G1 mode → G2 mode → G3 mode), the absolute value of the RFIC IIP3 value increases, which can reduce RX performance degradation (e.g., sensitivity degradation). As the gain of RFIC (501) decreases, the noise figure (NF) of RFIC increases, but the overall system sensitivity (e.g., default sensitivity) may not fluctuate significantly. Consequently, in a state where IMD components may occur (e.g., during 2TX operation), the gain mode of RFIC (501) is changed (e.g., by decreasing the gain of RFIC (501)) to increase the RFIC IIP3 characteristics, thereby improving RX performance (e.g., sensitivity).

[0090] Meanwhile, the electronic device (101) may also control the gain of at least one LNA (e.g., first LNA (505a) and / or second LNA (505b)) placed outside the RFIC (501) (e.g., included in the first RFFE (232) and / or second RFFE (234)) when the RF signal of the first uplink band of the first operating band and the RF signal of the second uplink band of the second operating band are output from the RFIC (501) at least simultaneously (e.g., 2TX operation).

[0091] External LNA gain mode G0 G1 G2 Gain[dB] 19 15 9.7 Desense[dB] 14 6.8 1.4 Default Sensitivity[dBm] -100 -99.3 -98.6

[0092] Referring to Table 2, as the gain of the external LNA (e.g., the first LNA (505a) and / or the second LNA (505b)) decreases (e.g., G0 mode → G1 mode → G2 mode), the degradation of RX performance (e.g., sensitivity degradation) may decrease. This indicates that as the gain of the external LNA (e.g., the first LNA (505a) and / or the second LNA (505b)) decreases, the magnitude of the IMD component, which is caused by the small magnitude of RF signals input from the external LNA (e.g., the first LNA (505a) and / or the second LNA (505b)) to the RFIC (501), decreases. As the gain of the external LNA (e.g., the first LNA (505a) and / or the second LNA (505b)) decreases, the overall system sensitivity (e.g., default sensitivity) may change. When referring to Table 1 together, the degree to which the overall system sensitivity (e.g., base sensitivity) changes when the gain of the external LNA (e.g., the first LNA (505a) and / or the second LNA (505b)) decreases may be relatively greater than the degree to which the overall system sensitivity (e.g., base sensitivity) changes when the gain of the RFIC (501) decreases.

[0093] FIG. 7 is a flowchart (700) for explaining a method for controlling the LNA gain of an RFIC (e.g., RFIC (501) of FIG. 5) depending on whether an electronic device (e.g., the electronic device (101) of FIG. 1) is operating 2TX according to various embodiments.

[0094] According to various embodiments, the electronic device (101) may be connected to a first network and a second network. According to various embodiments, the electronic device (101) may be connected to the first network and the second network and be in a state capable of generating and / or transmitting RF signals of the operating band of the first network (hereinafter, the first operating band) and the operating band of the second network (hereinafter, the second operating band) at least simultaneously (e.g., a state capable of performing a 2TX operation). Alternatively, in another example, it may be connected to one network while the 710 operation described below is being performed, and then the 720 operation may be performed after the addition of a secondary cell group (SCG) by the MR-DC is completed. Alternatively, in another example, while the 710 operation described below is being performed, a signal may be transmitted and received in one operating band of one network, and then the 720 operation may be performed after the addition of an SCC according to the CA setting is completed.

[0095] For example, the first network may be a first cellular network (e.g., the first cellular network (292) of FIG. 2a and / or FIG. 2b) (e.g., an LTE network), and the second network may be a second cellular network (e.g., the second cellular network (294) of FIG. 2a and / or FIG. 2b) (e.g., a 5G network). In this case, the first operating band may be an E-UTRA operating band, and the second operating band, which is different from the first operating band, may be an NR operating band. The RF signal of the first operating band (e.g., the RF signal of the first uplink band and / or the RF signal of the first downlink band) may be generated based on the first RAT (e.g., an E-UTRA), and the RF signal of the second operating band (e.g., the RF signal of the second uplink band and / or the RF signal of the second downlink band) may be generated based on the second RAT (e.g., an NR) which is different from the first RAT.

[0096] As another example, the first network and the second network may be a first cellular network (292) (e.g., an LTE network). In this case, the first operating band may be a first E-UTRA operating band (e.g., an operating band corresponding to the primary component carrier (PCC) of the CA), and the second operating band may be a second E-UTRA operating band different from the first E-UTRA operating band (e.g., an operating band corresponding to the secondary component carrier (SCC) of the CA). The RF signal of the first operating band (e.g., an RF signal of the first uplink band and / or an RF signal of the first downlink band) and the RF signal of the second operating band (e.g., an RF signal of the second uplink band and / or an RF signal of the second downlink band) may be generated based on a single RAT (e.g., an E-UTRA).

[0097] According to various embodiments, the electronic device (101) may control the RFIC (501) to set the gain of at least one of the first LNAs (e.g., LNA (601) of FIG. 6a) included in the RFIC (501) to process (e.g., amplify) a second RF signal of a first downlink band of a first operating band provided from the RFFE (e.g., first RFFE (232) and second RFFE (234) of FIG. 2a and / or FIG. 2b) to the RFIC (501) in operation 710, based on the output of a first RF signal of a first uplink band of a first operating band through the RFIC (e.g., RFIC (501) of FIG. 5). According to various embodiments, the electronic device (101) may determine the first gain by checking the received electric field (e.g., strength of the second RF signal) and determining the first gain based on the checked strength. For example, referring to FIG. 6b, the electronic device (101) can control the gain of at least one first LNA for processing the second RF signal in a hysteresis manner based on the received electric field (e.g., the strength of the second RF signal). Or, in another example, the first gain may be a default value, and there are no restrictions on the method of setting the first gain.

[0098] According to various embodiments, the electronic device (101) may control the RFIC (501) to set the gain of at least one first LNA for processing the second RF signal to a second gain, based on the fact that, in operation 720, a first RF signal and a third RF signal of a second uplink band of a second operating band different from the first operating band are output at least simultaneously through the RFIC (501). For example, while the electronic device (101) performs a 2TX operation, the RFIC (501) may generate a first RF signal of the first uplink band and a third RF signal of the second uplink band, and output the first RF signal and the third RF signal at least simultaneously to an RFFE (e.g., the first RFFE (232) and the second RFFE (234) of FIG. 2a and / or FIG. 2b). According to various embodiments, the electronic device (101) may determine the gain of at least one first LNA to be a second gain smaller than the first gain. According to one embodiment, the electronic device (101) can determine a second gain smaller than a first gain based on a received electric field (e.g., strength of a second RF signal). According to one embodiment, the electronic device (101) can control the RFIC (501) to determine a second gain or / or set the gain of at least one first LNA to the second gain when the transmission power (TX power) of the first RF signal and the third RF signal (e.g., strength of the first RF signal input to the first antenna module (242) of FIG. 2a and / or FIG. 2b) is greater than or equal to a threshold value based on the first RF signal and the third RF signal being output at least simultaneously through the RFIC (501).According to one embodiment, the electronic device (101) can control the RFIC (501) to determine a second gain when the first operating band and the second operating band are operating bands in which the IMD component of the first RF signal and the third RF signal can affect the RF signal of the downlink band, and / or set the gain of at least one first LNA to the second gain.

[0099] According to one embodiment, the electronic device (101) may control the gain of at least one LNA (e.g., first LNA (505a) and / or second LNA (505b)) disposed outside the RFIC (501) (e.g., included in the first RFFE (232) and / or second RFFE (234)) based on whether the first RF signal and the third RF signal are output at least simultaneously through the RFIC (501).

[0100] According to one embodiment, the electronic device (101) can change the highest gain mode of at least one first LNA based on the first RF signal and the third RF signal being output at least simultaneously through the RFIC (501). The electronic device (101) may also limit the maximum gain of at least one first LNA based on the first RF signal and the third RF signal being output at least simultaneously through the RFIC (501).

[0101] FIG. 8 is a flowchart (800) for illustrating a method for controlling the gain of at least one LNA (e.g., LNA (601) of FIG. 6a) for receiving a second RF signal based on a receiving electric field, according to various embodiments, in which an electronic device (e.g., the electronic device (101) of FIG. 1).

[0102] According to various embodiments, the electronic device (101) may be connected to a first network and a second network. According to various embodiments, the electronic device (101) may be connected to a first network and a second network and may be in a state capable of generating and / or transmitting RF signals of the operating band of the first network (hereinafter, first operating band) and the operating band of the second network (hereinafter, second operating band) at least simultaneously (e.g., a state capable of performing 2TX operation).

[0103] According to various embodiments, the electronic device (101) can determine the strength of a second RF signal (e.g., a received electric field) in operation 810. For example, the second RF signal may include an RF signal of the downlink band of the first operation band.

[0104] According to various embodiments, the electronic device (101) can determine, in operation 830, whether the first RF signal and the third RF signal are output at least simultaneously through the RFIC (e.g., RFIC (501) of FIG. 5) (e.g., whether the 2TX operation is being performed).

[0105] According to various embodiments, if the electronic device (101) determines that the first RF signal and the third RF signal are not output at least simultaneously (e.g., that either the first RF signal or the third RF signal is output), in operation 850, the first gain of at least one first LNA (e.g., LNA (601)) for processing the second RF signal can be determined based on the determined intensity. According to various embodiments, the electronic device (101) can control the RFIC (501) to set the gain of at least one first LNA (e.g., LNA (601)) to the determined first gain. For example, referring to FIG. 6b, the gain of at least one first LNA for processing the second RF signal can be controlled in a hysteresis manner based on the intensity of the second RF signal.

[0106] According to various embodiments, if the electronic device (101) confirms that the first RF signal and the third RF signal are output at least simultaneously, in operation 870, it may determine a second gain of at least one first LNA for processing the second RF signal based on the confirmed intensity. For example, the electronic device (101) may determine the second gain in a range smaller than the first gain. For example, referring to FIG. 6b, when the first gain is a gain corresponding to the G0 mode, the second gain may be determined as a gain corresponding to the G1 mode. In another example, the second gain is such that the intensity of the second RF signal is P C6 Even if reduced to a lower value, it can be determined as a gain corresponding to the G1 mode. According to various embodiments, the electronic device (101) can control the RFIC (501) to set the gain of at least one first LNA (e.g., LNA (601)) to a determined second gain.

[0107] According to various embodiments, the electronic device (101) may perform at least one of the operations 830 or lower by performing operation 810 again after performing operation 850 or operation 870.

[0108] FIG. 9 is a flowchart (900) for illustrating a method for controlling the gain of at least one LNA (e.g., LNA (601) of FIG. 6a) for receiving a second RF signal based on frequency ranges of a first operating band and a second operating band, according to various embodiments, in an electronic device (e.g., electronic device (101) of FIG. 1).

[0109] According to various embodiments, the electronic device (101) may be connected to a first network and a second network. According to various embodiments, the electronic device (101) may be connected to a first network and a second network and may be in a state capable of generating and / or transmitting RF signals of the operating band of the first network (hereinafter, first operating band) and the operating band of the second network (hereinafter, second operating band) at least simultaneously (e.g., a state capable of performing 2TX operation).

[0110] According to various embodiments, the electronic device (101) can identify at least one first frequency of a first uplink band and at least one second frequency of a second uplink band in operation 910. For example, at least one first frequency may include a frequency included in the frequency range of the first uplink band. For example, at least one second frequency may include a frequency included in the frequency range of the second uplink band.

[0111] According to various embodiments, the electronic device (101) can determine, in operation 930, whether at least one third frequency identified based on at least one first frequency and at least one second frequency is included in the first downlink band. For example, at least one third frequency may correspond to the IMD3 component of at least one first frequency and at least one second frequency. For example, referring to FIG. 4, the electronic device (101) can calculate the frequency of the IMD (e.g., IMD3) component (e.g., 2f1-f2 and / or 2f2-f1) based on at least one first frequency (e.g., f1) and at least one second frequency (e.g., f2). The electronic device (101) can determine whether the frequency of the calculated IMD component is included in the frequency range of the first downlink band. As described above, the electronic device (101) can determine the gain of the LNA by directly calculating the IMD component. Meanwhile, in another example, the electronic device (101) may store in advance information on combinations of operating bands that may affect the received RF signal by the transmitted RF signals in 2TX mode. The electronic device (101) may determine whether the operating bands of the 2TX modes correspond to the information stored in advance.

[0112] According to various embodiments, the electronic device (101) can determine a first gain of at least one first LNA (e.g., LNA (601)) for processing a second RF signal (e.g., RF signal of the first downlink band) in operation 950 when it is determined that at least one identified third frequency is not included in the first downlink band. For example, the electronic device (101) can determine the first gain based on the strength of the second RF signal (e.g., received electric field). According to various embodiments, the electronic device (101) can control the RFIC (501) to set the gain of at least one first LNA (e.g., LNA (601)) to the determined first gain.

[0113] According to various embodiments, the electronic device (101) can determine a second gain of at least one first LNA for processing a second RF signal in operation 970 when it is confirmed that at least one confirmed third frequency is included in the first downlink band. For example, the electronic device (101) can determine a second gain in a range smaller than the first gain. According to various embodiments, the electronic device (101) can determine a second gain of at least one first LNA (e.g., LNA (601)) based on the first RF signal and the third RF signal being output at least simultaneously when it is confirmed that at least one confirmed third frequency is included in the first downlink band, and control the RFIC (501) to set the gain of at least one first LNA (e.g., LNA (601)) to the determined second gain.

[0114] According to various embodiments, the electronic device (101) may perform operation 990 again after performing operation 950 or operation 970.

[0115] FIG. 10 is a flowchart (1000) for illustrating a method in which an electronic device (e.g., the electronic device (101) of FIG. 1) according to various embodiments controls the gain of at least one LNA (e.g., the LNA (601) of FIG. 6a) for receiving a second RF signal based on the transmission power (TX power) of a first RF signal and a third RF signal.

[0116] According to various embodiments, the electronic device (101) may be connected to a first network and a second network. According to various embodiments, the electronic device (101) may be connected to a first network and a second network and may be in a state capable of generating and / or transmitting RF signals of the operating band of the first network (hereinafter, first operating band) and the operating band of the second network (hereinafter, second operating band) at least simultaneously (e.g., a state capable of performing 2TX operation).

[0117] According to various embodiments, the electronic device (101) can determine the magnitude of the transmission power of the first RF signal and the third RF signal based on the fact that, in operation 1010, the first RF signal (e.g., RF signal of the first downlink band) and the third RF signal (e.g., RF signal of the second downlink band) are output at least simultaneously through an RFIC (e.g., RFIC (501) of FIG. 5). According to various embodiments, the electronic device (101) can determine the magnitude of the transmission power of the first RF signal and the third RF signal when the intensity (e.g., receiving electric field) of the second RF signal (e.g., RF signal of the first downlink band) is below a threshold intensity. For example, referring to FIG. 6b, the threshold intensity is P, where the gain of at least one first LNA is determined to be a gain corresponding to the G0 mode. C8It may include. According to various embodiments, the electronic device (101) can determine the magnitude of the transmission power of the first RF signal and the third RF signal when the gain of at least one first LNA exceeds a predetermined gain. For example, referring to FIG. 6b, the electronic device (101) can determine the magnitude of the transmission power of the first RF signal and the third RF signal when the gain of at least one first LNA exceeds a gain corresponding to the G1 mode, or when the gain mode of at least one first LNA is the G0 mode.

[0118] According to various embodiments, the electronic device (101) can determine whether the magnitude of the detected transmission power is greater than or equal to a threshold value in operation 1030.

[0119] According to various embodiments, the electronic device (101) can control the RFIC (501) to set the gain of at least one first LNA for receiving a second RF signal to a first gain in operation 1050 when it is determined that the magnitude of the detected transmission power is less than a threshold value. For example, the electronic device (101) can determine the first gain based on the strength of the second RF signal (e.g., receiving electric field).

[0120] According to various embodiments, the electronic device (101) can control the RFIC (501) to set the gain of at least one first LNA for receiving a second RF signal to a second gain in operation 1070 when it is confirmed that the magnitude of the confirmed transmission power is greater than or equal to a threshold value. For example, the electronic device (101) can determine the second gain in a range smaller than the first gain.

[0121] According to various embodiments, the electronic device (101) may perform at least one of operations 1030 or lower by performing operation 1010 again after performing operation 1050 or operation 1070.

[0122] FIG. 11 is a flowchart (1100) for illustrating a method for controlling the gain of at least one LNA (e.g., the first LNA (505a) and / or the second LNA (505b) of FIG. 5) which is placed outside of an RFIC (e.g., the RFIC (501) of FIG. 5) depending on whether 2TX is operated, in which case an electronic device (e.g., the electronic device (101) of FIG. 1) is placed outside of the RFIC (e.g., the RFIC (501) of FIG. 5) (e.g., included in the first RFFE (232) and / or the second RFFE (234) of FIG. 2a and / or FIG. 2b).

[0123] According to various embodiments, the electronic device (101) may be connected to a first network and a second network. According to various embodiments, the electronic device (101) may be connected to a first network and a second network and may be in a state capable of generating and / or transmitting RF signals of the operating band of the first network (hereinafter, first operating band) and the operating band of the second network (hereinafter, second operating band) at least simultaneously (e.g., a state capable of performing 2TX operation).

[0124] According to various embodiments, the electronic device (101) may control the RFFE (e.g., first RFFE (232) and / or second RFFE (234)) to set the gain of at least one second LNA (e.g., first LNA (505a) and / or second LNA (505b)) included in the RFFE (e.g., first RFFE (232) and second RFFE (234)) to a third gain based on the output of a first RF signal (e.g., first uplink band RF signal) through the RFIC (501) in operation 1110. For example, the third gain may be determined based on the strength (e.g., received electric field) of the second RF signal (e.g., first uplink band RF signal).

[0125] According to various embodiments, the electronic device (101) may control an RFFE (e.g., a first RFFE (232) and / or a second RFFE (234)) to set the gain of at least one first LNA for processing a second RF signal to a fourth gain, based on the fact that, in operation 1130, a first RF signal and a third RF signal (e.g., an RF signal of the second uplink band) are output at least simultaneously through the RFIC (501).

[0126] According to various embodiments, the above-described operation 1110 and / or operation 1130 may be performed in parallel (e.g., independently) with at least one operation controlling the gain of at least one first LNA of the RFIC (501) (e.g., LNA (601) of FIG. 6a). According to various embodiments, the above-described operation 1110 and / or operation 1130 may also be performed together with at least one operation controlling the gain of at least one first LNA of the RFIC (501) (e.g., LNA (601)).

[0127] FIG. 12 is a flowchart (1200) for explaining a method for controlling the maximum LNA gain of an RFIC (e.g., RFIC (501) of FIG. 5) depending on whether an electronic device (e.g., the electronic device (101) of FIG. 1) is operating 2TX according to various embodiments.

[0128] According to various embodiments, the electronic device (101) may be connected to a first network and a second network. According to various embodiments, the electronic device (101) may be connected to a first network and a second network and may be in a state capable of generating and / or transmitting RF signals of the operating band of the first network (hereinafter, first operating band) and the operating band of the second network (hereinafter, second operating band) at least simultaneously (e.g., a state capable of performing 2TX operation).

[0129] According to various embodiments, the electronic device (101) can determine in operation 1210 whether there is a combination of operating bands affected by IMD3. For example, the electronic device (101) can determine whether at least one third frequency identified based on at least one first frequency of the first uplink band and at least one second frequency of the second uplink band is included in the first downlink band. According to various embodiments, if the electronic device (101) determines that there is no combination of operating bands affected by IMD3, it can perform operation 1210 again.

[0130] According to various embodiments, if the electronic device (101) determines that the combination of operating bands affected by IMD3 is a combination of operating bands, it can determine in operation 1230 whether the 2TX operation is in progress (e.g., whether the 2TX operation is being performed). For example, the electronic device (101) can determine whether the first RF signal (e.g., RF signal of the first uplink band) and the third RF signal (e.g., RF signal of the second uplink band) are output at least simultaneously. According to various embodiments, if the electronic device (101) determines that the first RF signal and the third RF signal are not output at least simultaneously (e.g., if either the first RF signal or the third RF signal is output), it can perform operation 1230 again. According to various embodiments, the electronic device (101) can determine the gain of at least one first LNA (e.g., LNA (601) of FIG. 6a) in a range below the gain corresponding to the G0 mode based on the strength of the second RF signal (e.g., RF signal of the first downlink band) when it is confirmed that the first RF signal and the third RF signal are not output at least simultaneously.

[0131] According to various embodiments, when the electronic device (101) confirms that it is in a state of 2TX operation, in operation 1250, it can determine whether the received electric field corresponds to the G0 mode.

[0132] According to various embodiments, if the electronic device (101) confirms that the received electric field corresponds to the G0 mode, in operation 1270, it can determine whether the magnitude of the transmission power of the first RF signal and the third RF signal is greater than or equal to a threshold value. According to various embodiments, if the electronic device (101) confirms that the magnitude of the transmission power of the first RF signal and the third RF signal is less than a threshold value, it can perform operation 1250 again. According to various embodiments, if the electronic device (101) confirms that the magnitude of the transmission power of the first RF signal and the third RF signal is less than a threshold value, it can set the highest gain mode of at least one first LNA (e.g., LNA (601)) to the G0 mode. According to various embodiments, the electronic device (101) can set the gain mode of at least one first LNA (e.g., LNA (601)) to the G0 mode. For example, the electronic device (101) can set the gain of at least one first LNA (e.g., LNA (601)) to a gain corresponding to the G0 mode.

[0133] According to various embodiments, if the electronic device (101) determines that the magnitude of the transmission power of the first RF signal and the third RF signal is greater than or equal to a threshold value, in operation 1290, the upper gain mode of at least one first LNA (e.g., LNA (601)) can be set to G1 mode. According to various embodiments, the electronic device (101) can set the gain mode of at least one first LNA (e.g., LNA (601)) to a gain mode lower than G1 mode (e.g., G1, G2, G3, or G4). For example, the electronic device (101) can limit the gain of at least one first LNA (e.g., LNA (601)) (e.g., determined to a gain within a range lower than the gain corresponding to G1 mode). According to various embodiments, after performing operation 1290, the electronic device (101) can perform operation 1270 again.

According to various embodiments, the electronic device (101) may, based on the received electric field, set the gain mode of at least one first LNA (e.g., LNA (601)) to a gain mode lower than G1 mode (e.g., G0, G1, G2, G3, or G4).
