[0001] The present disclosure relates to an electronic device and a method for transmitting a transmission signal in the electronic device.

[0002] With recent advancements in mobile communication technology, the widespread use of mobile devices offering diverse functions has led to efforts to develop 5G communication systems to meet the growing demand for wireless data traffic. To achieve high data rates and provide faster data transfer speeds, 5G communication systems are being considered for implementation in higher frequency bands (e.g., 25-60 GHz) in addition to those used in 3G and LTE (long-term evolution) systems.

[0007] According to various embodiments, an electronic device may include a processor. According to one embodiment, the electronic device may include a memory that stores instructions. According to one embodiment, the instructions, when executed by the processor, may cause the electronic device to determine a first power of a first transmission signal corresponding to a first frequency band.

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).

[0062] 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)).

[0068] FIG. 2A is a block diagram (200) of an electronic device (101) for supporting legacy network communication and 5G network communication according to one embodiment of the present disclosure. Referring to FIG. 2A, the electronic device (101) may include a first communication processor (212), a second communication processor (214), a first radio frequency integrated circuit (RFIC) (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first radio frequency front end (RFFE) (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and antennas (248). The electronic device (101) may further include a processor (120) and a memory (130). The second network (199) may include a first cellular network (292) and a second cellular network (294). According to another embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a portion of the wireless communication module (192). According to another embodiment, the fourth RFIC (228) may be omitted or may be included as a part of the third RFIC (226).

[0069] The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and may support legacy network communication through the established communication channel. According to various embodiments, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. 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.

[0070] The first communication processor (212) can transmit and 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 and 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 and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).

[0071] 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 and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, 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 with the processor (120) (e.g., application processor) using shared memory.

[0072] 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, referring to 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).

[0073] 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).

[0074] 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).

[0075] 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).

[0076] 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.

[0077] 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.

[0078] 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).

[0079] 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.

[0080] 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 (130) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0081] FIGS. 3A, 3B, and 3C are diagrams illustrating wireless communication systems that provide a network of legacy communication and / or 5G communication according to one embodiment of the present disclosure. Referring to FIGS. 3A, 3B, and 3C, a network environment (300a, 300b, and 300c) may include at least one of a legacy network and a 5G network.

The above 5G network may include, for example, a New Radio (NR) base station (350) (e.g., gNB (gNodeB)) that supports wireless connection with an electronic device (101) and a 5th generation core (5GC) (352) that manages 5G communication of the electronic device (101).

[0085] According to various embodiments, in a DC environment, one of the LTE base stations (340) or the NR base station (350) may operate as a master node (MN) (310) and the other may operate as a secondary node (SN) (320). The MN (310) may be connected to a core network (230) and may transmit and receive control messages. The MN (310) and the SN (320) may be connected via a network interface and may transmit and receive messages related to management of radio resources (e.g., communication channels) to each other.

[0086] According to various embodiments, the MN (310) may be configured as an LTE base station (340), the SN (320) as an NR base station (350), and the core network (330) as 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).

[0087] According to various embodiments, the MN (310) may be configured as an NR base station (350), the SN (320) as an LTE base station (340), and the core network (330) as 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).

[0088] 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 from an electronic device (101).

[0089] Referring to FIG. 3c, the legacy network and the 5G network according to various embodiments can independently provide data transmission and reception. For example, the electronic device (101) and the EPC (342) can transmit and receive control messages and user data via the LTE base station (340). As another example, the electronic device (101) and the 5GC (352) can transmit and receive control messages and user data via the NR base station (350).

[0092] As described above, dual connectivity through an LTE base station (340) and an NR base station (350) may also be named EN-DC (E-UTRA new radio dual connectivity).

[0093] Hereinafter, the structure of an electronic device (101) according to various embodiments will be described in detail with reference to FIGS. 4a, 4b, 4c, 5a, 5b, 6, 7, 8, 9, and 10. In each drawing of the embodiments described below, one communication processor (260) and one RFIC (410) are illustrated as being connected to multiple RFFEs (431, 432), but the various embodiments described below are not limited thereto. For example, in the various embodiments described below, as illustrated in FIG. 2a or 2b, multiple communication processors (212, 214) and / or multiple RFICs (222, 224, 226, 228) may be connected to multiple RFFEs (431, 432), respectively.

[0094] FIGS. 4A and 4B illustrate block diagrams of an electronic device according to one embodiment of the present disclosure.

[0095] Referring to FIG. 4A, an electronic device (e.g., the electronic device (101) of FIG. 1) according to various embodiments may include a processor (120), a communication processor (260), an RFIC (410), a first RFFE (431), a second RFFE (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).

[0096] According to various embodiments, the RFIC (410) may, upon transmission, convert a baseband signal generated by the 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 an RF signal used in a 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 a 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 (e.g., NR) 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 (e.g., LTE) to a second antenna (442) or a third antenna (443) through a second RFFE (432). In another embodiment, the RFIC (410) may operate as a multi-input multi-output (MIMO) antenna by transmitting an RF signal corresponding to a first communication network (e.g., NR) or a second communication network (e.g., LTE) to a first antenna (441) or a fourth antenna (444) through a first RFFE (431), and transmitting an RF signal corresponding to the same first communication network (e.g., NR) or a second communication network (e.g., LTE) to a second antenna (442) or a third antenna (443) through a second RFFE (432).

[0097] According to various embodiments, the transmission 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 antenna transmission path (Ant Tx 1)'. The transmission 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 antenna transmission path (Ant Tx 4)'.

[0098] According to various embodiments, the RFIC (410) may, upon transmission, convert a baseband signal generated by the communication processor (260) into a radio frequency (RF) signal used in the first communication network or the 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 the second antenna (442) or the third antenna (443) via the second RFFE (432) and the second switch (452).

[0099] According to various embodiments, the transmission 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 antenna transmission path (Ant Tx 2)'. The transmission 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 antenna transmission path (Ant Tx 3)'.

[0100] According to various embodiments, upon receiving, an RF signal may be received from a first communication network via a first antenna (441) or a fourth antenna (444), and the received RF signal may be transmitted to a communication processor (260) via at least one RFIC. Additionally, an RF signal may be received from a first communication network or a second communication network via a second antenna (442) or a third antenna (443), and the received RF signal may be transmitted to a communication processor (260) via at least one RFIC.

[0101] According to various embodiments, the first communication network and the second communication network may be different communication networks. 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). When the first communication network is a 5G network, the first RFFE (431) may be designed to be suitable for processing signals corresponding to the 5G network, and the second RFFE (432) may be designed to be suitable for processing signals corresponding to a legacy network.

[0102] According to various embodiments, the frequency band of the signal transmitted through the first RFFE (431) and the frequency band of the signal transmitted through the second RFFE (432) may be the same, similar, or different. For example, the frequency band of the signal transmitted through the first RFFE (431) may be the N48 or N78 band (3.5 GHz), which is a frequency band of a 5G network, and may be the B48 band (3.5 GHz), which is a frequency band of an LTE network. The frequency band of the signal transmitted through the second RFFE (432) may be the B48 band (3.5 GHz), which is a frequency band of an LTE network. In this case, the first RFFE (431) and the second RFFE (432) process signals of the same or similar frequency bands, but the first RFFE (431) may be designed to enable signal processing suited to the characteristics of a 5G network, and the second RFFE (432) may be designed to enable signal processing suited to the characteristics of an LTE network.

[0103] According to various embodiments, when an electronic device transmits a signal through one of the first antenna (441) and the fourth antenna (444) via the first RFFE (431) and the first switch (451), and transmits a reference signal through the first antenna (441) and the fourth antenna (444), it may be referred to as '1T2R' since it uses one transmit antenna (Tx) and two receive antennas (Rx). According to various embodiments, when an electronic device transmits a signal through one of the second antenna (442) and the third antenna (443) via the second RFFE (432) and the second switch (452), and transmits a reference signal through the second antenna (442) and the third antenna (443), it may be referred to as '1T2R' since it uses one transmit antenna (Tx) and two receive antennas (Rx).

[0104] According to various embodiments, when the electronic device simultaneously transmits and receives data through the first RFFE (431) and the second RFFE (432), it may be referred to as '2T4R' since it uses two transmit antennas (Tx) and four receive antennas (Rx). The electronic device illustrated in FIG. 4A may operate in 1T2R or 2T4R according to various embodiments, and thus may be referred to as an electronic device supporting '1T2R / 2T4R'.

[0105] According to various embodiments, the communication processor (260) may control to transmit a reference signal (e.g., a sounding reference signal (SRS)) referenced for channel estimation at a base station of the first communication network to at least one antenna (the first antenna (441) or the fourth antenna (444)) among the plurality of antennas of the first antenna group through the first RFFE circuit (431). According to various embodiments, the communication processor (260) may control to additionally transmit the reference signal referenced for channel estimation at a base station of the first communication network to at least one antenna (the second antenna (442) or the third antenna (443)) among the plurality of antennas of the second antenna group through the second RFFE circuit (432). When the electronic device transmits a reference signal through the first antenna (441), the second antenna (442), the third antenna (443), and the fourth antenna (444), the base station of the first communication network can receive the reference signal and perform channel estimation through the received reference signal. The base station of the first communication network can transmit a beamformed signal for the first antenna (441), the second antenna (442), the third antenna (443), and the fourth antenna (444). The electronic device can receive a signal transmitted from the base station of the first communication network through the first antenna (441), the second antenna (442), the third antenna (443), and the fourth antenna (444). The electronic device illustrated in the above-described FIG. 4A is designed as an electronic device supporting '1T2R / 2T4R', but according to various embodiments, it can operate as '1T4R' by transmitting a reference signal to a base station of the first communication network through the first antenna (441), the second antenna (442), the third antenna (443), and the fourth antenna (444).

For example, the first RFFE (431) may be disposed at an upper portion within a housing of the electronic device (101), and the second RFFE (432) may be disposed at a lower portion than the first RFFE (431) within the housing of the electronic device (101), but the various embodiments of the present disclosure are not limited to the above-described placement positions. In the embodiment of FIG. 4B described below, a description that is commonly applicable to the aforementioned FIG. 4A will be omitted.

[0107] According to various embodiments, the RFIC (410) may, upon transmission, convert a baseband signal generated by the 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 an RF signal used in a first communication network to a first antenna (441) or a fourth antenna (444) via a first RFFE (431) and a first switch (451).

[0113] FIG. 5A and FIG. 5B are diagrams showing reference signal transmission of an electronic device according to one embodiment of the present disclosure.

[0114] Referring to FIG. 5A, an electronic device (101) (e.g., the electronic device (101) of FIG. 1) can transmit a reference signal (e.g., SRS) through four antennas (e.g., a first antenna (511), a second antenna (512), a third antenna (513), and a fourth antenna (514)). For example, the electronic device (101) can amplify the reference signal through at least one power amplifier (PA) (515) and transmit the amplified reference signal through at least one switch (516) to the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514). The reference signal (e.g., SRS) transmitted through each antenna (e.g., first antenna (511), second antenna (512), third antenna (513), fourth antenna (514)) of the electronic device (101) can be received through each antenna (521) of the base station (520) (e.g., gNB).

[0115] According to various embodiments, the base station (520) may receive a reference signal transmitted from the electronic device (101) and estimate a channel for each antenna (e.g., first antenna (511), second antenna (512), third antenna (513), and fourth antenna (514)) of the electronic device (101) from the received reference signal. The base station (520) may transmit a beamformed signal to each antenna of the electronic device (101) based on the channel estimate.

[0116] In Fig. 5a, for convenience of explanation, the power amplifier (515) and the switch (516) are illustrated as one and connected to a plurality of antennas (the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514)), but those skilled in the art will readily understand that the present invention is not limited thereto. For example, the electronic device (101) may include components included in the electronic device (101) illustrated in Fig. 4a or 4b.

[0117] Referring to FIG. 5B, the base station (520) can transmit the beamformed signal through an array antenna (521) including a plurality of antennas (e.g., 32). The signal transmitted from the base station (520) can be received through each antenna (e.g., the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514)) of the electronic device (101), and as illustrated in FIG. 5B, the signal can be received in the form of a beam directed to each antenna (e.g., the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514)) of the electronic device (101) by beamforming of the base station (520).

[0118] As illustrated in the above FIGS. 5A and 5B, when the electronic device (101) transmits a reference signal (e.g., SRS) through multiple transmission paths, the base station (520) can check the channel environment with respect to each antenna (e.g., the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514)) of the electronic device (101) and perform beamforming, and as a result, the reference signal received power (RSRP) and / or signal to noise ratio (SNR) of the downlink channel can be improved. When the RSRP and / or SNR of the downlink channel are improved, the rank index (RI) or channel quality indicator (CQI) for the corresponding electronic device can be increased. The base station (520) may assign a high rank or MCS (modulation and code schemes) to the electronic device (101) based on the improved performance of the electronic device (101), thereby improving the downlink throughput of the electronic device (101).

[0119] According to various embodiments, the base station (520) may use a downlink reference signal for downlink channel estimation. For example, when the base station (520) transmits the downlink reference signal to the electronic device (101), the electronic device (101) may receive the downlink reference signal transmitted from the base station (520) and perform channel estimation. The electronic device (101) may transmit the result of the channel estimation to the base station (520), and the base station (520) may perform downlink beamforming with reference to the result of the channel estimation transmitted from the electronic device (101). According to various embodiments, when the base station (520) performs channel estimation by the reference signal (e.g., SRS) transmitted by the electronic device (101), the channel estimation may be performed faster than the channel estimation by the downlink reference signal.

[0120] According to various embodiments, a first communication network (e.g., a base station (gNB)) or a second communication network (e.g., a base station (eNB)) may request various configuration information of the electronic device (101) by transmitting a UE Capability Enquiry message to the electronic device (101). For example, the first communication network (e.g., a base station (gNB)) or the second communication network (e.g., a base station (eNB)) may request information related to a receiving antenna of the electronic device (101) through the UE Capability Enquiry message. The electronic device (101) may receive the UE Capability Enquiry message from the first communication network or the second communication network, and in response, transmit a UE Capability Information message to the first communication network or the second communication network. According to various embodiments, the UE Capability Information message may include information related to the receiving antenna of the electronic device (101), such as 'supportedSRS-TxPortSwitch t1r4', corresponding to the contents of the UE Capability Enquiry message.

[0121] As the information related to the above antenna is described as 'supportedSRS-TxPortSwitch t1r4', the first communication network determines that the electronic device (101) can transmit a signal using four receiving antennas, and can transmit information about the time at which a reference signal (e.g., SRS) is to be transmitted for each of the four antennas by including it in the RRC Reconfiguration message.

[0122] FIG. 6 illustrates a flowchart for explaining a signal transmission and reception procedure between an electronic device and a communication network according to one embodiment of the present disclosure.

[0123] Referring to FIG. 6, the electronic device (101) can establish an RRC connection with a first communication network (e.g., a base station (gNB)) (600) through a random access channel (RACH) procedure.

[0124] According to various embodiments, in operation 610, the first communication network (600) may transmit an RRC Reconfiguration message to the electronic device (101). For example, the first communication network (600) may transmit the RRC Reconfiguration message in response to an RRC Request message transmitted by the electronic device (101). As described above, the RRC Reconfiguration message may include information regarding the timing at which the electronic device (101) transmits a reference signal (e.g., SRS) for each antenna, as shown in Table 1 below.

[0125] perodicityAndOffset-p s120:17perodicityAndOffset-p s120:7perodicityAndOffset-p s120:13perodicityAndOffset-p s120:3nrofSymbols n1

[0126] Referring to the above RRC Reconfiguration message, the time (duration) for transmitting SRS can be determined by the allocated symbol (symbol) as described as “nrofSymbols n1.” In one embodiment, with reference to the RRC Reconfiguration message, the first SRS may be set to be transmitted in the 17th slot while transmitting once every 20 slots, as described as "periodicityAndOffset-p s120: 17", the second SRS may be set to be transmitted in the 7th slot while transmitting once every 20 slots, as described as "periodicityAndOffset-p s120: 7", the third SRS may be set to be transmitted in the 13th slot while transmitting once every 20 slots, as described as "periodicityAndOffset-p s120: 13", and the fourth SRS may be set to be transmitted in the 3rd slot while transmitting once every 20 slots, as described as "periodicityAndOffset-p s120: 3".

[0127] According to various embodiments, the electronic device (101) may transmit four SRSs through each antenna at different times for every 20 slots according to the setting of the RRC Reconfiguration. The size of one slot may be determined by the subcarrier spacing (SCS). For example, when the SCS is 30 KHz, the time interval of one slot may be 0.5 ms, and the time interval of 20 slots may be 10 ms. Accordingly, the electronic device (101) may repeatedly transmit the SRS through each antenna at different times for every 10 ms period. According to various embodiments, one slot may include 14 symbols, and assuming that one symbol is allocated for transmission of one SRS, it may have a symbol duration (or symbol enable time) of 0.5 ms * 1 / 14 = 35 μs (0.035 ms).

[0128] According to various embodiments, in operation 620, the electronic device (101) may transmit an RRC Reconfiguration Complete message to the first communication network (600). As the RRC Reconfiguration procedure is normally completed, in operation 630, the electronic device (101) and the first communication network (600) may complete RRC connection setup.

[0129] Referring again to FIGS. 4A and 4B , according to various embodiments, the communication processor (260) and / or the RFIC (410) may transmit a reference signal at different times for each set time period (e.g., 10 ms) through each antenna transmission path (e.g., the first antenna transmission path, the second antenna transmission path, the third antenna transmission path, the fourth antenna transmission path) based on information regarding the transmission time of the reference signal (e.g., SRS) received from the first communication network (600) as described above.

[0130] FIG. 7 is a diagram showing a transmission period of a reference signal according to one embodiment of the present disclosure. Referring to FIG. 7, for example, a first SRS may be transmitted through a first antenna (441) (RX0) in the 17th slot among 20 slots every 10 ms, a second SRS may be transmitted through a second antenna (442) (RX1) in the 7th slot, a third SRS may be transmitted through a third antenna (443) (RX2) in the 13th slot, and a fourth SRS may be transmitted through a fourth antenna (444) (RX3) in the 3rd slot.

[0131] According to various embodiments, the reference signal may be, but is not limited to, a sounding reference signal (SRS) used for multi-antenna signal processing (e.g., multi-input multi-output (MIMO) or beamforming) through uplink channel state measurement.

[0132] FIG. 8 is a block diagram illustrating the structure of an electronic device according to one embodiment of the present disclosure.

[0133] Referring to FIG. 8, the electronic device (101) can transmit a first transmission signal or SRS through the first RFFE (811) and each antenna (the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514)). For example, the electronic device (101) can transmit the first transmission signal to the first antenna (511) or the first transmission signal to the fourth antenna (514) through the first RFFE (811). The electronic device (101) can transmit the first transmission signal to the second antenna (512) or the first transmission signal to the third antenna (513) through the first RFFE (811). The electronic device (101) can transmit the SRS to the second antenna (512) or the third antenna (513) through the first RFFE (811). The electronic device (101) can transmit a second transmission signal through the second RFFE (821) and each antenna (the first antenna (511), the second antenna (512), the third antenna (513), and the fourth antenna (514)).

[0134] FIG. 9 is a diagram illustrating an antenna of an electronic device according to one embodiment of the present disclosure.

[0135] Referring to FIG. 9, according to one embodiment, the electronic device (101) may include a plurality of antennas. For example, the electronic device (101) may include three main antennas in the lower body, namely, a first main antenna (911), a second main antenna (912), and a third main antenna (913). The first main antenna (911) may process signals in frequency bands corresponding to a low band (LB) and a mid band (MB). The third main antenna (913) may process signals in frequency bands corresponding to a mid band (MB) and a high band (HB).

[0136] According to one embodiment, the electronic device (101) may include six sub-antennas on the upper body, namely, a first sub-antenna (921), a second sub-antenna (922), a third sub-antenna (923), a fourth sub-antenna (924), a fifth sub-antenna (925), and a sixth sub-antenna (926). The first sub-antenna (921) may process a signal in a frequency band corresponding to a high band (HB) or a low band (LB). The second sub-antenna (922) may process a signal in a frequency band corresponding to the high band (HB) and a WiFi signal. The third sub-antenna (923) may process a signal in a frequency band corresponding to a middle band (MB). The fourth sub-antenna (924) may process a global positioning system (GPS) signal and a WiFi signal. The fifth sub-antenna (925) may process a signal in a frequency band corresponding to the middle band (MB). The frequency bands corresponding to the low band (LB), mid band (MB), and high band (HB) above can be variously set by the operator. In one embodiment, within the frequency band of 300 MHz to 300 GHz, the band below 1 GHz can be classified as the low band (LB), the band between 1 GHz and 6 GHz can be classified as the mid band (MB), and the band above 6 GHz can be classified as the high band (HB). However, this is merely an example and is not limited to the above figures. For example, the high band (HB) can also be referred to as a frequency above 3.5 GHz.

[0137] According to one embodiment, a first transmission signal (e.g., a signal of the B48, N48, N78 band) corresponding to a first frequency band (e.g., a frequency band of 3.5 GHz) may be set to be amplified to a set size through the first RFFE (811) and then transmitted through the second sub-antenna (922). According to one embodiment, the first transmission signal corresponding to the first frequency band may be set to be amplified to a set size through the first RFFE (811) and then transmitted through the first sub-antenna (921).

[0138] According to one embodiment, the SRS signal may be configured to be amplified to a set size through the first RFFE (811) and then transmitted through the fifth sub-antenna (925). According to one embodiment, the SRS signal may be configured to be amplified to a set size through the first RFFE (811) and then transmitted through the third main antenna (913).

[0139] The RFFE and antenna through which each signal described above is transmitted are described as an example, and the first transmission signal or SRS can be transmitted by various combinations of RFFEs and antennas.

[0140] FIG. 10 illustrates a block diagram of an electronic device according to one embodiment of the present disclosure. 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).

[0141] 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 the 3rd sub antenna (1073) through a duplexer to provide MIMO or diversity with the 3rd 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).

[0142] 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 FIGS. 4A, 4B, 4C, and 9. 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), and the fourth antenna (444) described above in FIGS. 4A, 4B, and 4C. At least one of the antennas of FIG. 10 may correspond to any one of the first main antenna (911), the second main antenna (912), and the third main antenna (913) described above in FIG. 9. At least one of the antennas of FIG. 10 may correspond to any one of the first sub-antenna (921), the second sub-antenna (922), the third sub-antenna (923), the fourth sub-antenna (924), the fifth sub-antenna (925), and the sixth sub-antenna (926) described above in FIG. 9.

[0143] FIG. 11 illustrates a block diagram of an electronic device according to one embodiment of the present disclosure.

[0144] According to various embodiments, the electronic device (101) may include a communication processor (1110) (e.g., at least one of the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) and an RFIC (1120) (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)).

[0145] According to one embodiment, the electronic device (101) may include at least one of: at least one amplifier (1130, 1150, 1170) (e.g., a power amplifier (PA); at least one switch (1135, 1155, 1175) (e.g., a switching circuit or a switch box); or at least one antenna (1141, 1142, 1143, 1144, 1161, 1162, 1163, 1164, 1181, 1182, 1183, 1184). For convenience of explanation, in FIG. 11, components for transmitting RF signals are illustrated as being included in the electronic device (101); however, those skilled in the art will appreciate that components for receiving and / or processing RF signals may additionally be included in the electronic device (101).

[0146] In one embodiment, each of the amplifiers and each switch may be configured within a single integrated circuit (IC) or may be configured as separate integrated circuits. For example, the first amplifier (1130) and the first switch (1135) may be configured as a single first module (e.g., a first power amplifier module (PAM)). The second amplifier (1150) and the second switch (1155) may be configured as a single second module (e.g., a second PAM). The third amplifier (1170) and the third switch (1175) may be configured as a single third module (e.g., a third PAM).

[0147] According to various embodiments, the communication processor (1110) may support multiple RATs (e.g., LTE communication and NR communication). Protocol stacks for multiple RATs (e.g., a 3GPP protocol stack for LTE communication and a 3GPP protocol stack for NR communication) may be defined (or stored) in the communication processor (1110). The protocol stack may receive a data packet (or IP packet) from an application processor (e.g., processor (120)) (or TCP / IP stack), process the data packet, and output the data packet. When an RF signal received from the outside is converted into a baseband signal and received, the protocol stack may process the baseband signal and provide the baseband signal to the application processor (e.g., processor (120)) (or TCP / IP stack). The protocol stack may perform an operation for signaling (e.g., control).

[0148] According to various embodiments, the RFIC (1120) may process a signal (e.g., a baseband signal) received from the communication processor (1110) and output an RF signal. The RFIC (1120) may be referred to as a transceiver, but is not limited to the term. At least one amplifier (1130, 1150, 1170) may amplify and provide a received RF signal. As the at least one amplifier (1130, 1150, 1170) is controlled, the output power of the RF signal may be adjusted. According to one embodiment, the SRS of the NR communication may be transmitted through each of the first antenna (1141), the second antenna (1142), the third antenna (1143), and the fourth antenna (1144). For example, the electronic device (101) may support 1T4R, and the first antenna (1141) may be an antenna capable of both transmitting and receiving, and the second antenna (1142), the third antenna (1143), and the fourth antenna (1144) may be antennas for receiving. The communication processor (1110) may check the power of the transmission signal and control the first amplifier (1130) so that the checked power of the transmission signal is applied to the port for each antenna. The first switch (1135) may selectively connect the RFIC (1120) and the antenna so that the RF signal is applied to a designated antenna. For example, in the example of FIG. 11, although a signal in the N78 frequency band is illustrated as being transmitted, a signal in the N77 or B48 frequency band may also be transmitted, and there is no limitation on the frequency band. Additionally, those skilled in the art will understand that the number of antennas (1141, 1142, 1143, 1144) for NR communication is exemplary and there is no limitation.

[0149] According to various embodiments, the electronic device (101) may support carrier aggregation (CA) for LTE. For example, in the embodiment of FIG. 11, the frequency band B7 associated with the PCell may be selected, and at least one frequency band (not shown) associated with the SCell may be selected. There may be no limitation on the number of component carriers (CCs) for CA. However, depending on hardware constraints and the frequency bands operated by the operator, the number may typically be 2 to 32. A signal associated with the PCell may be transmitted and received through at least one of the antennas (1161, 1162, 1163, 1164) via the second amplifier (1150) and / or the second switch (1155). A signal associated with SCell may be transmitted and received through at least one of the antennas (1181, 1182, 1183, 1184) via the third amplifier (1170) and / or the third switch (1175). The number of antennas (1161, 1162, 1163, 1164) and the antennas (1181, 1182, 1183, 1184) is also exemplary. According to various embodiments, multiple frequency bands may correspond to one antenna. For example, the antennas (1161, 1162, 1163, 1164) may correspond to an ultra high band (UHB) (e.g., N78, N79), as well as a high band (e.g., frequency bands 7, 38, 39, 40, 41). Accordingly, those skilled in the art will understand that the number of antennas may be implemented to be smaller than in FIG. 11.

[0150] FIG. 12 illustrates a block diagram illustrating a method for determining maximum transmittable power according to one embodiment of the present disclosure.

[0151] Referring to FIG. 12, according to various embodiments, the maximum transmittable power (Tx Max Power) for each transmission path may be set by considering at least one of the maximum transmittable power (P-MAX Power) (PeMax) received from each communication network (e.g., a base station), the maximum transmittable power for each transmission path (UE Tx MAX Power; PcMax) set in the electronic device (101), and the SAR event maximum transmittable power (SAR EVENT MAX Power) set in response to each SAR event by considering the SAR (specific absorption rate) backoff. For example, the maximum transmittable power (Tx Max Power) may be determined as the minimum value among the plurality of maximum transmittable powers exemplified above (e.g., P-MAX Power, UE Tx MAX Power, SAR EVENT MAX Power), but is not limited thereto. According to various embodiments, the SAR event maximum transmittable power may be set differently for each SAR event (e.g., a grip event or a proximity event).

[0152] According to various embodiments, the maximum transmittable power (P-MAX Power) (PeMax) received from the communication network (e.g., base station) may be set differently according to the power class (PC) that each communication network or electronic device can support. For example, when the power class is PC2, it may be determined as a value (e.g., 27 dBm) within a range set based on 26 dBm, and when the power class is PC3, it may be determined as a value (e.g., 24 dBm) within a range set based on 23 dBm. According to various embodiments, the maximum transmittable power (UE Tx MAX Power; PcMax) for each transmission path set in the electronic device (101) may differ depending on whether the RFFE for each transmission path is different or whether the length of each transmission path is different.

[0153] In the embodiments described below, the power of the transmission signal may be set so as not to exceed the maximum transmittable power (Tx Max Power). According to one embodiment, the power of the transmission signal may correspond to the power output from an amplifier (e.g., amplifiers 1130, 1150, 1170 of FIG. 11) and the power of a signal supplied to each antenna (e.g., antennas 1141, 1142, 1143, 1144, 1161, 1162, 1163, 1164, 1181, 1182, 1183, 1184 of FIG. 11)). For example, the power of the transmission signal may also be referred to as conduction power or target power, but is not limited to the above terms.

[0154] According to one embodiment, the power of the transmission signal (e.g., conduction power or target power) may be changed in real time according to the changing channel conditions and may be determined according to transmitting power control (TPC) by the base station. For example, the electronic device (101) may determine the power of the transmission signal based on the following <Mathematical Formula 1> according to the standard document 3GPP TS 38.213.

[0155]

[0156] The definition of the above <Mathematical Formula 1> can follow 3GPP TS 38.213, for example, P O_PUSCH,b,f,c(j) can be provided by p0 for the activated uplink bandwidth part (UL BWP) (b) of the carrier (f) of the serving cell (c). M PUSCH RB,b,f,c (i) is the bandwidth expressed as the number of resource blocks for a transmission occasion (i) on an activated UL BWP (b) of a carrier (f) of a serving cell (c), and μ is the subcarrier spacing (SCS). α b,f,c(j) can be provided by alpha for the activation UL BWP of the carrier (f) of the serving cell (c). PL b,f,c (q d ) is the RS resource index (q) for the activated downlink BWP (DL BWP) of the serving cell (c). d ) is the downlink path loss predicted in dB by the UE (user equipment). f b,f,c (i) can follow 3GPP TS 38.213 and is a value that can be adjusted by downlink control information (DCI) transmitted from the base station to the electronic device.

[0157] According to various embodiments, the electronic device (101) may determine the power of the transmission signal determined based on the above <Mathematical Formula 1> within a range that does not exceed the above-described maximum transmission power (Tx Max Power). For example, if the maximum transmission power of the electronic device is set to 21 dBm and the power of the transmission signal determined based on the above <Mathematical Formula 1> is 22 dBm, the transmission power for transmitting uplink data (e.g., PUSCH data) in the electronic device (101) may be limited to 21 dBm.

[0158] FIG. 13 illustrates a beam pattern of an antenna according to one embodiment of the present disclosure.

[0159] Referring to FIG. 13, each antenna (1301) included in the electronic device (101) (e.g., antennas (911, 912, 913, 921, 922, 923, 924, 925, 926) of FIG. 9) may have a specific beam pattern. As the antenna (1301) has a specific beam pattern, antenna gain may be generated.

[0160] According to one embodiment, when the antenna (1301) is assumed to be an isotropic antenna, the beam pattern (1311) of the isotropic antenna may exhibit a circular shape as illustrated. When the antenna (1301) is a dipole antenna, the beam patterns (1312a, 1312b) of the dipole antenna may exhibit two oval shapes as illustrated. When the antenna (1301) is a directional antenna for a specific direction, the beam patterns (1313a, 1313b) of the directional antenna may exhibit a sharper shape in the specific direction as illustrated. Referring to FIG. 13, the antenna gain of the dipole antenna with respect to the isotropic antenna may be assumed to be 2.15 dB. In addition, the antenna gain of the directional antenna with respect to the dipole antenna may be expressed as dBd, and the antenna gain of the directional antenna with respect to the isotropic antenna may be expressed as dBi.

[0161] According to one embodiment, the effective isotropical radiated power (EIRP) may be expressed as the product of the power (Pt) of the transmission signal supplied to the antenna (1301) (e.g., conduction power or target power) and the absolute gain (Ga) for the isotropic antenna, as in <Mathematical Equation 2> below.

[0162]

[0163] According to one embodiment, referring to the above <Mathematical Formula 2>, if it is assumed that the antenna gain for the isotropic antenna is 10 dBd and the power of the transmission signal is 30 dBm (e.g., 1 W), the effective radiated power (ERP), which is the power output from the isotropic antenna, can be calculated as 40 dBm (e.g., 10 W) as in the following <Mathematical Formula 3>.

[0164]

[0165] Assuming that the antenna gain for the dipole antenna in the above <Mathematical Formula 3> is 2.15 dB, the EIRP, which is the power output from the dipole antenna, can be calculated as 42.15 dBm (e.g., 16.4 W) as in <Mathematical Formula 4> below.

[0167] According to one embodiment, even if the power (Pt) of a transmission signal output from an amplifier (e.g., a power amplifier) ​​to an antenna is less than or equal to a set maximum transmission power, as illustrated in FIG. 13, the power actually output from the antenna may be relatively greater due to the antenna gain.

[0168] According to one embodiment, the maximum output power of a signal output from an antenna may be limited for a specific frequency band (e.g., a 3.5 GHz frequency band) for various purposes (e.g., protecting a radar work band). Accordingly, even if the power (Pt) of a transmission signal output from the antenna is less than or equal to a set maximum transmission power, there may be a case where the maximum output standard limited by the antenna gain is exceeded. For example, assuming that the maximum output standard for a specific frequency band (e.g., B48, N48, N78) of a specific group is 23.0 dBm and the maximum transmission power of the transmission signal is 23.0 dBm, the antenna gain may be set to 0 dBi or less in order to satisfy the maximum output standard of the specific group. In one embodiment, when the maximum transmit power of a transmission signal is 23.0 dBm and the antenna output power of a specific frequency band (e.g., B48, N48, N78) is 24.0 to 25.0 dBm due to the antenna gain, a situation may occur where the maximum output standard of the specific group is exceeded. In one embodiment, in order to meet the maximum output standard of the specific group (e.g., 23.0 dBm), the maximum transmit power of the transmission signal may be lowered by 1 dB to 22.0 dBm. In this way, when the maximum transmit power of the transmission signal is lowered, the maximum output standard of the specific group may be met, but not only the transmit power but also the performance of the received signal may be degraded. For example, the occurrence of the performance deterioration of the received signal may cause problems of RF performance deterioration, such as a call drop phenomenon in a weak electric field and a deterioration of throughput (T-put) performance.

[0169] FIG. 14 is a graph showing performance degradation of an electronic device according to one embodiment of the present disclosure.

[0170] Referring to FIG. 14, the antenna gain can be reduced by modifying the antenna matching to satisfy the EIRP specification for the frequency range of 3.5 GHz to 3.8 GHz. For example, modifying the antenna matching for the frequency range of 3.5 GHz to 3.8 GHz can result in a 2 to 3 dB degradation in antenna performance. For example, by reducing the maximum transmit power (e.g., conduction power or target power) of the transmit signal and the antenna gain, the EIRP of the corresponding frequency band (e.g., B48, N48, N78) can be reduced to 21.5 to 22.0 dBm to satisfy the specification. In this way, when the specification is satisfied by reducing the antenna gain together with the maximum transmit power, the power of the transmit signal can be reduced not only in the specific frequency band but also in all frequency band sections. In addition, as the antenna gain is reduced, the reception performance of the antenna can be degraded. The above degradation of transmission and reception performance may appear as a decrease in transmission and reception rate and a decrease in throughput performance in a weak electric field.

[0171] In the various embodiments described below, various embodiments that can satisfy the EIRP specification in a specific frequency band without reducing the maximum transmit power and antenna gain will be described.

[0180] Referring to FIG. 16, according to one embodiment, an RF circuit (1600) may include an amplifier (1610) (e.g., a power amplifier (PA)), band pass filters (BPFs) (e.g., a first BPF (1620), a second-first BPF (1651), a second-second BPF (1652)), a coupler (1630), a switching circuit (1640) (e.g., a switch box or an antenna switch module (ASM)), and a low noise amplifier (LNA) (e.g., a second-first LNA (1661), a second-second LNA (1662)). According to one embodiment, the RF circuit (1600) may be referred to as an RFFE, a front end module (FEM), a power amplifier module (PAM), a power amplifier module with integrated duplexer (PAMiD), an LNA PAMiD (LPAMiD), or a front end module with integrated duplexer (FEMid) depending on the function or included components, but is not limited to the above terms.

[0181] According to one embodiment, as illustrated in FIG. 16, the amplifier (1610) and the switching circuit (1640) may be included in a single semiconductor chip or integrated circuit constituting the RF circuit (1600). According to one embodiment, the switching circuit (1640) may be configured as a separate module external to the RF circuit (1600). According to one embodiment, the RF circuit (1600) may be configured as a semiconductor chip or an integrated integrated circuit integrated with the aforementioned RF IC (1120). For example, the amplifier (1610) and / or the switching circuit (1640) included in the RF circuit (1600) may be configured as a semiconductor chip or an integrated integrated circuit integrated with the aforementioned RFIC (1120).

[0182] According to one embodiment, a first transmission signal corresponding to a first frequency band (e.g., N77 or N78) output from an RFIC (e.g., RFIC (1120) of FIG. 11) may be amplified to a first power (e.g., conduction power or target power) through an amplifier (1610) of the RF circuit (1600). The first transmission signal amplified by the amplifier (1610) may be band-filtered through a first BPF (1620) and input to a switching circuit (1640) via a coupler (1630). The first transmission signal input to the switching circuit (1640) through the coupler (1630) may be transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) through the first antenna connection terminal (ANT1) at the time of transmission, or may be transmitted to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) through the second antenna connection terminal (ANT2). For example, the switching circuit (1640) may connect the terminal connected to the coupler (1630) to the first antenna connection terminal (ANT1) at the time of transmission of the first transmission signal. The first transmission signal may be transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) through the first antenna connection terminal (ANT1) of the switching circuit (1640). The switching circuit (1640) can connect the terminal connected to the coupler (1630) to the second antenna connection terminal (ANT2) at the time of transmission of the first transmission signal. The first transmission signal can be output through the second antenna connection terminal (ANT2) of the switching circuit (1640) and transmitted to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9).

[0183] According to one embodiment, an SRS output from an RFIC (e.g., RFIC (1120) of FIG. 11) may be amplified to a power set for SRS through an amplifier (1610) of the RF circuit (1600). The SRS amplified in the amplifier (1610) may be band-filtered through a first BPF (1620) and input to a switching circuit (1640) via a coupler (1630). The SRS input to the switching circuit (1640) through the coupler (1630) may be transmitted to a third main antenna (e.g., the third main antenna (913) of FIG. 9) or a fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9) through an SRS connection terminal (ANT3_SRS) at the time of SRS transmission. In one embodiment, the coupler (1630) may be used to sense the power of the first transmission signal or SRS. For example, a signal coupled through the coupler (1630) may be fed back to an RFIC (e.g., RFIC (1120) of FIG. 11) or a communication processor (e.g., communication processor (1110) of FIG. 11) to sense the transmission power.

[0184] According to one embodiment, a signal received through the first antenna connection terminal (ANT1) or the second antenna connection terminal (ANT2) may be filtered through the 2-1 BPF (1651), amplified through the 2-1 LNA (1661), and then input to an RFIC (e.g., RFIC (1120) of FIG. 11).

[0185] According to one embodiment, the switching circuit (1640) may be controlled by a control signal (SW_CTRL) of a processor (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2A, FIG. 2B, or FIG. 2C). For example, the switching circuit (1640) may be controlled by a logic table set as shown in Table 2 below.

[0186] PortSW_CTRLANT1ANT2ANT3_SRS

[0187] According to one embodiment, referring to the above , a first transmission signal corresponding to a first frequency band input to a switching circuit (1640) via the coupler (1630) may be transmitted to an ANT1, ANT2, or ANT3_SRS port by a control signal (SW_CTRL) of a processor (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2A, FIG. 2B, or FIG. 2C). For example, when the control signal (SW_CTRL) is a signal corresponding to ANT1, the first transmission signal may be transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) via the ANT1 port. When the control signal (SW_CTRL) is a signal corresponding to ANT2, the first transmission signal may be transmitted to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) via the ANT2 port. When the above control signal (SW_CTRL) is a signal corresponding to ANT3_SRS, the SRS can be transmitted to the third main antenna (e.g., the third main antenna (913) of FIG. 9) or the fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9) through the ANT3_SRS port.

[0188] According to one embodiment, even if the first power (e.g., conduction power or target power) of the first transmission signal corresponding to the first frequency band output from the amplifier (1610) as described above in the description of FIG. 13 is less than or equal to the set maximum transmission power, the power actually output from the antenna may be greater than the first power due to the antenna gain.

[0189] According to one embodiment, the maximum output of a signal output from an antenna may be limited for various purposes (e.g., radar work band protection) for a specific frequency band (e.g., B48, N48, N78). Accordingly, even if the first power of a first transmission signal output from the antenna is lower than or equal to the maximum transmission power set for the specific frequency band, there may be a case where the maximum output standard limited by the antenna gain is exceeded. For example, assuming that the maximum output standard for a specific frequency band (e.g., B48, N48, N78) set by a specific organization is 23.0 dBm and the maximum transmission power of the first transmission signal is 23.0 dBm, the antenna gain may be set to 0 dBi or less in order to satisfy the maximum output standard of the specific organization. In one embodiment, when the maximum transmission power of the first transmission signal is 23.0 dBm and the antenna output power of a specific frequency band (e.g., B48, N48, N78) is 24.0 to 25.0 dBm due to the antenna gain, a situation may occur where the maximum output standard of the specific group is exceeded. In one embodiment, in order to meet the maximum output standard of the specific group (e.g., 23.0 dBm), the maximum transmission power of the first transmission signal may be lowered by 1 dB to 22.0 dBm. In this way, when the maximum transmission power of the first transmission signal is lowered, the maximum output standard of the specific group may be met, but not only the transmission power but also the performance of the received signal may be degraded. For example, the occurrence of the performance deterioration of the received signal may cause problems of RF performance deterioration, such as a call drop phenomenon in a weak electric field and a deterioration of throughput (T-put) performance.

[0190] In the embodiments described below, when transmitting a first transmission signal corresponding to the specific frequency band, the first transmission signal is transmitted simultaneously through a plurality of antennas, thereby satisfying the maximum output standard for the set specific frequency band without adjusting the matching circuit of the antenna or reducing the maximum transmission power.

For example, the amplifier (1710) and / or the switching circuit (1740) included in the RF circuit (1700) may be configured as a semiconductor chip or an integrated integrated circuit integrated with the aforementioned RFIC (1120).

[0194] According to one embodiment, a first transmission signal corresponding to a first frequency band (e.g., N77 or N78) output from an RFIC (e.g., RFIC (1120) of FIG. 11) may be amplified to a first power (e.g., conduction power or target power) through an amplifier (1710) of the RF circuit (1700).

For example, the switching circuit (1740) can simultaneously connect the terminal connected to the coupler (1730) to the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2) at the time of transmission of the first transmission signal.

[0197] Referring to FIG. 17c, the first transmission signal may be simultaneously transmitted to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and a third main antenna (e.g., the third main antenna (913) of FIG. 9) at the time of transmission, or to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and a fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9) at the time of transmission. For example, the switching circuit (1740) may simultaneously connect the terminal connected to the coupler (1730) to the second antenna connection terminal (ANT2) and the third antenna connection terminal (ANT3_SRS) at the time of transmission of the first transmission signal. The first transmission signal may be simultaneously transmitted to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and a third main antenna (e.g., the third main antenna (913) of FIG. 9) through the second antenna connection terminal (ANT2) and the third antenna connection terminal (ANT3_SRS) of the switching circuit (1740), or may be simultaneously transmitted to a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and a fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9).

[0198] Referring to FIG. 17d, the first transmission signal may be simultaneously transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9), a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9), and a third main antenna (e.g., the third main antenna (913) of FIG. 9), or a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9), a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9), and a fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9)) at the time of transmission of the first transmission signal.

[0199] According to one embodiment, referring to FIG. 17E, the switching circuit (1740) may connect the terminal connected to the coupler (1730) through which the first transmission signal is output to a CAL terminal. The CAL terminal may be connected to a processor (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2B or 2C) or an RFIC (1120). The processor (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2B or 2C) or an RFIC (1120) may measure the power of the first transmission signal from a signal received through the CAL terminal. For example, the RF circuit (1700) may have different path loss for each manufactured product, and the characteristics of each component may be different. Accordingly, the processor (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2A) or the RFIC (1120) may be calibrated so that power corresponding to the power control signal is input to the switching circuit (1740) based on the signal received through the CAL terminal. According to one embodiment, the calibration may be performed during product manufacturing, or may be performed whenever a specific event occurs while the RFIC (1120) is operating, or at set cycles.

[0200] According to one embodiment, the switching circuit (1740) may be controlled by a control signal (SW_CTRL) of a processor (e.g., the processor (120) of FIG. 2b or FIG. 2c or the integrated communication processor (260)). For example, the switching circuit (1740) may be controlled based on a logic table set as shown in Table 3 below.

[0203] According to one embodiment, when the control signal (SW_CTRL) is a signal corresponding to ANT1 + ANT2, the first transmission signal can be simultaneously transmitted to the second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) and the first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) through the ANT1 port and the ANT2 port. When the above control signal (SW_CTRL) is a signal corresponding to ANT1 + ANT3_SRS, the first transmission signal may be simultaneously transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) and a third main antenna (e.g., the third main antenna (913) of FIG. 9) through the ANT1 port and the ANT3_SRS port, or may be simultaneously transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) and a fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9). When the above control signal (SW_CTRL) is a signal corresponding to ANT2 + ANT3_SRS, the first transmission signal may be simultaneously transmitted to the first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and the third main antenna (e.g., the third main antenna (913) of FIG. 9) through the ANT2 port and the ANT3_SRS port, or may be simultaneously transmitted to the first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and the fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9).When the control signal (SW_CTRL) corresponds to ANT1 + ANT2 + ANT3_SRS, the first transmission signal may be simultaneously transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9), a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and a third main antenna (e.g., the third main antenna (913) of FIG. 9) via the ANT1 port, the ANT2 port and the ANT3_SRS port, or may be simultaneously transmitted to a second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9), a first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and a fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9). When the above control signal (SW_CTRL) is a signal corresponding to CAL, the first transmission signal can be transmitted to a processor (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2b or 2c) or RFIC (1120) through the CAL port.

[0204] According to one embodiment, the first transmission signal is transmitted simultaneously through at least two antennas (e.g., two antennas or three antennas), thereby reducing the power output through each antenna without degrading the performance of the antennas. Even if the amplifier (1710) outputs the first transmission signal at the maximum transmission power, the first transmission signal is distributed to a plurality of paths and transmitted through the plurality of antennas, thereby reducing the power transmitted to each antenna. For example, if the first power of the first transmission signal output from the amplifier (1710) is 23 dBm and the first transmission signal is distributed and transmitted through two antennas via the switching circuit (1740), a power of 20 dBm can be transmitted to each antenna. Accordingly, the power radiated from each antenna can satisfy a maximum output standard (e.g., 23.0 dBm) of a specific frequency band set for each antenna even when antenna gain is applied at the power of 20 dBm. For example, assuming that the maximum output standard for a specific frequency band of a specific group (e.g., B48, N48, N78) as described above is 23.0 dBm, and assuming that the maximum transmission power of the first transmission signal is 23.0 dBm, the maximum output standard can be satisfied by simultaneously transmitting the first transmission signal through at least two antennas without lowering the antenna gain through a matching circuit.

[0205] FIG. 18 illustrates a flowchart for explaining an operation method of an electronic device according to one embodiment of the present disclosure.

[0206] Referring to FIG. 18, according to various embodiments, at operation 1802, a processor (e.g., the processor 120 of FIG. 2B or FIG. 2C or the integrated communication processor (260)) of the electronic device (101) may determine a first power of a first transmission signal corresponding to a first frequency band (e.g., B48, N48, N78). According to one embodiment, the first power of the first transmission signal may correspond to a power measured between an output of an amplifier (e.g., the amplifier 1710 of FIGS. 17A-17E) and an input of a switching circuit (e.g., the switching circuit 1740 of FIGS. 17A-17E) within an RF circuit (e.g., the RF circuit 1700 of FIGS. 17A-17E).

[0207] According to one embodiment, the first power of the first transmission signal may be a power determined based on the aforementioned <Mathematical Formula 1>. For example, the first power may be referred to as conduction power or target power, but is not limited to the above terms. According to one embodiment, as described above in the description of FIG. 12, the first power may be set so as not to exceed the maximum transmittable power (Tx Max Power).

[0208] According to various embodiments, at operation 1804, a processor of the electronic device (101) (e.g., the processor (120) or the unified communication processor (260) of FIG. 2B or 2C) may determine that the first power of the first transmission signal corresponding to the first frequency band (e.g., B48, N48, N78) is equal to or greater than a set second power. According to one embodiment, the second power may correspond to a maximum power set in relation to an EIRP specification. The second power may be set to a specific value (e.g., 23.0 dBm) or a specific range (e.g., 23.0 dBm to 25.0 dBm). According to one embodiment, at operation 1804, the processor of the electronic device (101) may determine that the first power of the first transmission signal corresponding to the first frequency band (e.g., B48, N48, N78) is a set maximum power (e.g., 25 dBm).

[0209] According to one embodiment, the power of the first transmission signal may be set to be divided into a plurality of sections. For example, the power of the first transmission signal may be set to be divided into a low power section, a mid power section, a high power section, or a max power section. According to one embodiment, the max power section may correspond to a section that violates the EIRP specification. For example, the max power section may be set to 23.0 dBm to 25.0 dBm. According to one embodiment, in operation 1804, the processor of the electronic device (101) may determine that the first power of the first transmission signal corresponds to the max power section.

[0210] According to various embodiments, in operation 1806, a processor of the electronic device (101) (e.g., the processor (120) or the unified communication processor (260) of FIG. 2B or 2C) may determine a transmission time of the first transmission signal. According to one embodiment, when the first frequency band operates according to a time division duplexing (TDD) scheme, the transmission time of the first transmission signal may be determined by a transmission / reception pattern received from a network (e.g., a base station). According to one embodiment, the electronic device (101) may receive an RRC reconfiguration message (e.g., an RRC reconfiguration message or an RRC connection reconfiguration message) from the network. The electronic device (101) can check the time division-uplink-downlink configuration as shown in below based on the time division-uplink-downlink-configuration information (e.g., tdd-UL-DL-ConfigurationCommon IE) included in the RRC reset message.

[0211] tDD-UL-DL-ConfigCommon{referenceSubcarrierSpacing kHz30,pattern1{dl-UL-TransmissionPeriodicity ms2p5,nrofDownlinkSlots 3nrofDownlinkSymbols 10nrofUplinkSlots 1nrofUplinkSymbols 2pattern2}{dl-UL-TransmissionPeriodicity ms2p5,nrofDownlinkSlots 2nrofDownlinkSymbols 10nrofUplinkSlots 2nrofUplinkSymbols 2}}

[0212] The example in above may be information in an RRC reconfiguration message when the network instructs to alternately use Pattern 1 and Pattern 2. Pattern 1 may indicate that the period is 2.5ms, the number of slots and symbols corresponding to the downlink is 3 slots and 10 symbols, and the number of slots and symbols corresponding to the uplink is 1 slot and 2 symbols, in which case the guard period may be 2 symbols. Pattern 2 may indicate that the period is 2.5ms, the number of slots and symbols corresponding to the downlink is 2 slots and 10 symbols, and the number of slots and symbols corresponding to the uplink is 2 slots and 2 symbols, in which case the guard period may be 2 symbols. below is an example of various patterns of TDD.

[0213] DDDD / UU

[0214] In the above , a slot of "D" may mean that all symbols in the slot are downlink symbols (e.g., the slot format is 0). A slot of "U" may mean that all symbols in the slot are uplink symbols (e.g., the slot format is 1). A slot of "D / U" may mean that downlink symbols and uplink symbols are mixed in the slot (e.g., the slot format is a value other than 0 or 1).

[0215] According to various embodiments, in operation 1808, a processor of the electronic device (101) (e.g., the processor (120) or the integrated communication processor (260) of FIG. 2B or FIG. 2C) may control the first transmission signal to be transmitted simultaneously through at least two antennas (e.g., two antennas or three antennas) at the transmission time of the confirmed first transmission signal based on determining that the first power of the first transmission signal corresponding to the first frequency band (e.g., B48, N48, N78) is equal to or greater than the set second power. According to one embodiment, as described above in the description of FIGS. 17A to 17E, the processor of the electronic device (101) may control a switch circuit (e.g., a switch circuit (1740) of FIGS. 17A to 17E) by a control signal (SW_CTRL) as shown in , thereby setting the first transmission signal to be simultaneously transmitted to at least two ports (e.g., two ports or three ports) among ANT1, ANT2, and ANT3_SRS.

[0216] According to one embodiment, the first transmission signal can be transmitted simultaneously through at least two antennas, thereby reducing the power output through the antennas without degrading the performance of the antennas. For example, even if the first transmission signal is output at maximum transmission power from an amplifier (e.g., an amplifier (1710) of FIGS. 17A to 17E) included in an RF circuit (e.g., an RF circuit (1700) of FIGS. 17A to 17E) as described above, the power transmitted to one antenna can be reduced because the first transmission signal is distributed to a plurality of paths and transmitted through a plurality of antennas. For example, even if the antenna gain is not lowered through a matching circuit in the electronic device (101), the maximum output standard set in relation to the EIRP standard can be satisfied by simultaneously transmitting the first transmission signal through at least two antennas.

[0217] FIG. 19 illustrates a flowchart for explaining an operation method of an electronic device according to one embodiment of the present disclosure.

[0218] Referring to FIG. 19, according to various embodiments, in operation 1902, a processor (e.g., processor (120) or integrated communication processor (260) of FIG. 2B or FIG. 2C) of an electronic device (101) may transmit and receive a signal in a first frequency band (e.g., B48, N48, N78) in a call-connected state. According to one embodiment, the embodiment of FIG. 19 exemplifies a call-connected state, but may be performed in the same or similar manner in an RRC-connected state where a call is not connected.

[0219] According to various embodiments, at operation 1904, a processor of the electronic device (101) (e.g., processor (120) or integrated communication processor (260) of FIG. 2A) may determine a transmission time of a first transmission signal corresponding to the first frequency band (e.g., B48, N48, N78). According to one embodiment, if in operation 1904 it is not a transmission time (1904-No) and in operation 1918 it is a reception time, the processor of the electronic device (101) can set the first antenna connection terminal (ANT1) to be connected to the reception circuit (e.g., the 2-1 BPF (1751) or the 2-2 BPF (1752) of FIGS. 17a to 17e) by transmitting a control signal (SW_CTRL) to the switching circuit (e.g., the switching circuit (1740) of FIGS. 17a to 17e)) of FIG. 1720.

[0220] According to various embodiments, in operation 1904, if it is a transmission point (operation 1904-Yes), the processor of the electronic device (101) may check whether the first power of the first transmission signal is the set maximum power (Max Power) in operation 1906. For example, the maximum power may correspond to the maximum power set in relation to the EIRP specification. As a result of the check, if the first power of the first transmission signal is not the maximum power (operation 1906-No) (e.g., less than the maximum power), the processor of the electronic device (101) may set the first antenna connection terminal (ANT1) to be connected to the output of the amplifier (e.g., the amplifier 1710 of FIGS. 17a to 17e) by transmitting a control signal (SW_CTRL) to a switching circuit (e.g., the switching circuit 1740 of FIGS. 17a to 17e) in operation 1920. For example, the processor of the electronic device (101) may transmit a control signal (SW_CTRL) to a switching circuit (e.g., a switching circuit (1740) of FIGS. 17A to 17E) (e.g., a switching box or ASM) at operation 1920 to set the first transmission signal of the first power to be transmitted to the second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) via the first antenna connection terminal (ANT1).

[0221] According to various embodiments, the above operation 1906 may be performed before the above operation 1904. For example, the processor of the electronic device (101) may be configured to determine the transmission time after confirming whether the first power of the first transmission signal is the set maximum power.

[0222] According to various embodiments, in operation 1906, if the first power of the first transmission signal is the maximum power (operation 1906-Yes), the processor of the electronic device (101) may check the RSRP (reference signals received power) of the signals received at each antenna port (e.g., ANT1, ANT2, ANT3_SRS) in operation 1908. According to one embodiment, as a result of the check, the processor of the electronic device (101) may control the switching circuit (1740) (e.g., a switching box or ASM) so that the first transmission signal is output through two antenna ports that received signals having the highest RSRP.

[0223] According to various embodiments, when the RSRP of the signal received through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2) is relatively higher, in operation 1910, the processor of the electronic device (101) may input a control signal (SW_CTRL) corresponding to ANT1 + ANT2 to the switching circuit (1740) (e.g., a switching box or ASM) to control the first transmission signal to be simultaneously transmitted to the second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) and the first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) through the ANT1 port and the ANT2 port.

[0224] According to various embodiments, when the RSRP of the signal received through the first antenna connection terminal (ANT1) and the third antenna connection terminal (ANT3_SRS) is relatively higher, in operation 1914, the processor of the electronic device (101) may input a control signal (SW_CTRL) corresponding to ANT1 + ANT3_SRS to the switching circuit (1740) (e.g., a switching box or ASM) to control the first transmission signal to be simultaneously transmitted to the second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) and the third main antenna (e.g., the third main antenna (913) of FIG. 9)) through the ANT1 port and the ANT3_SRS port, or to be simultaneously transmitted to the second sub-antenna (e.g., the second sub-antenna (922) of FIG. 9) and the fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9).

[0225] According to various embodiments, when the RSRP of the signal received through the second antenna connection terminal (ANT2) and the third antenna connection terminal (ANT3_SRS) is relatively higher, in operation 1916, the processor of the electronic device (101) may input a control signal (SW_CTRL) corresponding to ANT2 + ANT3_SRS to the switching circuit (1740) (e.g., a switching box or ASM) to control the first transmission signal to be simultaneously transmitted to the first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and the third main antenna (e.g., the third main antenna (913) of FIG. 9)) through the ANT2 port and the ANT3_SRS port, or may control the first sub-antenna (e.g., the first sub-antenna (921) of FIG. 9) and the fifth sub-antenna (e.g., the fifth sub-antenna (925) of FIG. 9)) to be simultaneously transmitted.

[0226] According to various embodiments, at operation 1912, the processor of the electronic device (101) (e.g., the processor (120) or the unified communication processor (260) of FIG. 2B or FIG. 2C) may repeat the aforementioned procedure while the call is maintained (operation 1912—Yes). The processor of the electronic device (101) may terminate the aforementioned procedure when the call is terminated (operation 1912—No).

[0227] As described above with reference to FIGS. 18 and 19, according to various embodiments, for a specific frequency band (e.g., a first frequency band) in which power is limited with respect to EIRP, the performance of the received signal can be maintained by simultaneously transmitting the first transmission signal through multiple antennas via multiple paths only at the time of transmission, thereby providing optimal antenna performance in low power, medium power, and high power sections. In addition, by distributing the first transmission signal to multiple antenna paths in a section in which the first transmission signal has maximum transmission power, not only the EIRP can be improved, but also the null state of the antenna beam can be overcome. In addition, the problem of antenna performance deterioration due to holding the electronic device (101) can be overcome.

[0228] FIGS. 20A, 21A, and 22A are graphs showing vertical output of an antenna according to various embodiments of the present disclosure. FIGS. 20B, 21B, and 22B are graphs showing horizontal output of an antenna according to various embodiments.

[0229] According to various embodiments of the present disclosure, referring to FIGS. 20A and 20B , when the first transmission signal is transmitted only through the first antenna connection terminal (ANT1), the output of the antenna can be confirmed. For example, FIGS. 20A and 20B show vertical output and horizontal output at 30 degrees, 60 degrees, 90 degrees, 120 degrees, and 150 degrees when the first transmission signal is transmitted only through the first antenna connection terminal (ANT1).

[0230] According to various embodiments, referring to FIGS. 21A and 21B, the output of the antenna can be confirmed when the first transmission signal is transmitted only through the second antenna connection terminal (ANT2). For example, FIGS. 21A and 21B show the vertical output and horizontal output at 30 degrees, 60 degrees, 90 degrees, 120 degrees, and 150 degrees when the first transmission signal is transmitted only through the second antenna connection terminal (ANT2).

[0231] According to various embodiments, referring to FIGS. 22a and 22b, when the first transmission signal is transmitted simultaneously through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2), the output of the antenna can be checked. For example, FIGS. 22a and 22b show the vertical output and the horizontal output at 30 degrees, 60 degrees, 90 degrees, 120 degrees, and 150 degrees when the first transmission signal is transmitted simultaneously through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2).

[0232] According to various embodiments, as illustrated in FIGS. 22a and 22b, when the first transmission signal is simultaneously transmitted through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2), it can be confirmed that the null point improvement effect is exhibited. For example, when the first transmission signal is simultaneously transmitted by distributing it through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2), it can be confirmed that the EIRP standard is satisfied by measuring 22.27 dBm at an angle corresponding to the peak power of 25.27 degrees.

[0233] According to various embodiments, as illustrated in FIG. 22a, when the first transmission signal is transmitted simultaneously through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2), it can be confirmed that the vertical output in the 30 to 60 degree section and the 60 to 120 degree section shows an improvement of 7 to 13 dB compared to when the signal is transmitted through a single antenna connection terminal. In addition, as illustrated in FIG. 22a, when the first transmission signal is transmitted simultaneously through the first antenna connection terminal (ANT1) and the second antenna connection terminal (ANT2), it can be confirmed that the vertical output in the 300 to 330 degree section and the 60 to 120 degree section shows an improvement of 9 to 18 dB compared to when the signal is transmitted through a single antenna connection terminal. According to one embodiment, the electronic device (101) can improve the transmission and reception performance by about 2 dB by transmitting the first transmission power through an optimal single antenna in a low power or medium power section. The above RF performance improvement is advantageous for MCS allocation and can have the effect of improving throughput.
