Description

Electronic device, method and non-transitory storage medium for controlling input voltage of power amplifier

[0001] The present disclosure relates to an electronic device, method and non-transitory storage medium for controlling an input voltage of a power amplifier in a wireless communication system.

[0002] With the recent advancements in mobile communication technology, the widespread use of mobile devices offering diverse functions has led to efforts to develop wireless communication systems into 5G systems to meet the growing demand for wireless data traffic. To achieve high data rates and provide faster data transfer speeds, 5G systems are being considered for implementation in higher frequency bands (e.g., 25-60 GHz) in addition to the frequency bands used in 3G and LTE (long term evolution) systems. As one example, electronic devices may communicate with satellites based on the 5G NTN (non-terrestrial networks) standard.

[0003] Stand-alone (SA) and non-stand-alone (NSA) methods are being considered for implementing 5G communications. Among these, NSA may include EN-DC (LTE NR - Dual Connectivity), which utilizes a new radio (NR) system alongside the existing LTE system. In NSA, user terminals can utilize both the eNB of the LTE system and the gNB of the NR system. The technology that enables user terminals to utilize different communication systems is called dual connectivity.

[0004] In order to transmit a signal from an electronic device to a communication network (e.g., a base station), data generated from a processor or a communication processor within the electronic device may be processed through a radio frequency integrated circuit (RFIC) and a radio frequency front end (RFFE) circuit, and then transmitted to the outside of the electronic device through at least one antenna. The electronic device may include at least one antenna to transmit signals of various frequency bands. The at least one antenna may be configured to support signals of multiple frequency bands based on a multiplexer. The electronic device may determine the output of a power amplifier within the RFFE circuit based on an allowed maximum transmission power for stable communication at the cell edge.

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

[0006] When an electronic device (e.g., UE) transmits a transmission signal, the input voltage (VCC voltage) of the power amplifier (PA) is set according to the output power. As the input voltage changes, the capacitor of the modulator that supplies voltage to the PA can be repeatedly charged and discharged. The capacitor contracts when discharging and expands when charging, and as this repeated contraction / expansion occurs, noise can be generated, which can affect call quality.

[0007] In the way 5G communications are implemented (e.g., NR or / and NSA), the biggest cause of audio noise in voice calls may be the change (or difference) in input voltage due to changes in the transmission channel (e.g., physical random access channel (PRACH), physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), sounding reference signal (SRS)) set for each slot.

[0008] According to one embodiment of the present disclosure, an electronic device, a method, and a non-transitory storage medium are provided for controlling an input voltage of a power amplifier so as to improve call quality by reducing audio noise of audio data caused by a change (or difference) in input voltage according to a change in a transmission channel set for each slot.

[0009] According to one embodiment of the present disclosure, an electronic device may include a wireless communication circuit including at least one power amplifier, a first modulator, a second modulator, and a switch having one end connected to the at least one power amplifier and the other end connected to the first modulator or the second modulator, at least one processor operatively connected to the wireless communication circuit, and a memory storing instructions.

[0010] According to one embodiment, the instructions may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to connect the at least one power amplifier to the first modulator via the switch, such that a first input voltage is supplied from the first modulator to the at least one power amplifier based on a type of a transmission channel configured to transmit a signal according to a communication method implementing wireless communication being a first type set to a first power.

[0011] According to one embodiment, the instructions may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to connect the at least one power amplifier to the second modulator via the switch to supply a second input voltage lower than the first input voltage from the second modulator to the at least one power amplifier based on a change in the type of the transmission channel to a second type set to a second power that is lower by a specified value than the first power.

[0012] According to one embodiment, an operating method in an electronic device may include an operation of connecting at least one power amplifier of a wireless communication circuit of the electronic device to a first modulator through a switch of the wireless communication circuit, such that a first input voltage is supplied from a first modulator of the wireless communication circuit to the at least one power amplifier of the wireless communication circuit, based on a type of a transmission channel set to transmit a signal according to a communication method implementing wireless communication being a first type set to a first power.

[0013] According to one embodiment, the method may include connecting the at least one power amplifier to the second modulator via the switch so that a second input voltage lower than the first input voltage is supplied from the second modulator of the wireless communication circuit to the at least one power amplifier based on the type of the transmission channel being changed to a second type set to a second power that is lower by a specified value than the first power.

[0014] In one embodiment, one end of the switch may be connected to the at least one amplifier, and the other end of the switch may be connected to the first modulator or the second modulator.

[0015] According to one embodiment, a non-transitory storage medium storing one or more programs includes instructions that, when executed by at least one processor of an electronic device, cause the electronic device to execute an operation of connecting at least one power amplifier to a first modulator of a wireless communication circuit of the electronic device through a switch of the wireless communication circuit so that a first input voltage is supplied from a first modulator of the wireless communication circuit to at least one power amplifier of the wireless communication circuit based on a type of a transmission channel set to transmit a signal according to a communication method for implementing wireless communication being a first type set to a first power, and an operation of connecting the at least one power amplifier to a second modulator of the wireless communication circuit so that a second input voltage lower than the first input voltage is supplied from a second modulator of the wireless communication circuit to the at least one power amplifier through the switch so that an input voltage of the at least one power amplifier is switched to a second input voltage lower than the first input voltage so that a second input voltage lower than the first input voltage is supplied to the at least one power amplifier, the switch having one end connected to the at least one amplifier, and the switch having one end connected to the at least one amplifier, The other end may be connected to the first modulator or the second modulator.

[0054] Referring to FIG. 2A, an electronic device (101) according to one embodiment 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 at least one processor (120) and a memory (130).

According to another embodiment, the fourth RFIC (228) may be omitted or may be included as a part of the third RFIC (226).

[0055] According to one embodiment, the first communication processor (212) may support the establishment of a communication channel in a band to be used for wireless communication with the first cellular network (292), and legacy network communication through the established communication channel. According to one embodiment, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. According to one embodiment, the second communication processor (214) may support the establishment of 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 5G network communication through the established communication channel. According to one embodiment, 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.

[0056] According to one embodiment, 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).

[0057] 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.

[0058] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented in a single chip or a single package. According to various embodiments, the first communication processor (212) or the second communication processor (214) may be formed in a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2B, the integrated communication processor (260) may support functions for communicating with both the first cellular network (292) and the second cellular network (294).

[0059] According to one embodiment, 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).

[0060] According to one embodiment, 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).

[0061] According to one embodiment, the third RFIC (226) may convert a 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 a second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Above6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and preprocessed via the third RFFE (236). The third RFIC (226) may convert the preprocessed 5G Above6 RF signal into a baseband signal so that it may be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) may be formed as a part of the third RFIC (226).

[0062] According to one embodiment, the electronic device (101) may 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.

[0063] In 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. In 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 may be connected to the first RFFE (232) and the second RFFE (234) to 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). In 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 of the first antenna module (242) or the second antenna module (244) may be omitted or combined with another antenna module to process RF signals of a corresponding plurality of bands.

[0064] In 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. This allows the electronic device (101) to improve the quality or speed of communication with a second cellular network (294) (e.g., a 5G network).

[0065] In 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.

[0066] 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)).

[0067] FIGS. 3A, 3B, and 3C are diagrams illustrating wireless communication systems providing a network of legacy communication and / or 5G communication according to one embodiment.

[0068] Referring to FIGS. 3A, 3B, and 3C, the network environment (300a to 300c) may include at least one of a legacy network and a 5G network. The legacy network may include, for example, a 4G or LTE base station (340) (e.g., an eNodeB (eNB)) of the 3GPP standard that supports wireless connection with the electronic device (101) and an evolved packet core (EPC) (342) that manages 4G communication. The 5G network may include, for example, a New Radio (NR) base station (350) (e.g., a gNodeB (gNB)) that supports wireless connection with the electronic device (101) and a 5th generation core (5GC) (352) that manages 5G communication of the electronic device (101).

[0069] Referring to FIG. 3A, an electronic device (101) according to one embodiment can transmit and receive at least one of a control message or user data to and from at least a part of a 5G network (e.g., an NR base station (350), 5GC (352)) using at least a part of a legacy network (e.g., an LTE base station (340), EPC (342)).

[0070] According to one embodiment, the network environment (300a) may include a network environment that provides wireless communication dual connectivity (DC) to an LTE base station (340) and an NR base station (350), and transmits and receives control messages with an electronic device (101) through a core network (330) of one of the EPC (342) or 5GC (352).

[0071] According to one embodiment, 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 (330) 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.

[0072] According to one embodiment, 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).

[0073] According to one embodiment, 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).

[0074] Referring to FIG. 3b, according to one embodiment, 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).

[0075] Referring to FIG. 3c, according to one embodiment, the legacy network and the 5G network 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).

[0076] According to one embodiment, the electronic device (101) can be registered with at least one of the EPC (342) or the 5GC (352) to transmit and receive control messages.

[0077] According to one embodiment, the EPC (342) or the 5GC (352) may interwork to manage communication of the electronic device (101). For example, movement information of the electronic device (101) may be transmitted and received through an interface between the EPC (342) and the 5GC (352).

[0078] 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).

[0079] FIG. 4 is a diagram illustrating the configuration of a wireless communication module of an electronic device according to one embodiment. FIGS. 5A and 5B are diagrams illustrating examples of electric field verification through reception sensitivity according to one embodiment. FIGS. 6 to 9 are diagrams illustrating examples of changes in input voltage according to one embodiment.

[0080] Referring to FIGS. 1 to 4, an electronic device (101) according to one embodiment (e.g., the electronic device (101) of FIGS. 1 to 2B) may include at least one processor (120), a memory (130), a wireless communication module (401), and an antenna module (197) (e.g., the first antenna module (242), the second antenna module (244), and the third antenna module (246) of FIGS. 2A and 2B).

[0081] According to one embodiment, the wireless communication module (401) may include at least one communication processor, at least one RFIC, a first modulator (411), a second modulator (412), a power amplification module (420), and a switch (430). The wireless communication module (401) may be a circuit that performs signal processing to transmit a transmission signal for a voice call through the antenna module (197).

[0082] According to one embodiment, the electronic device (101) may perform signal processing through the wireless communication module (401) to transmit a transmission signal according to a method (e.g., NR SA or / and NSA) of implementing wireless communication (e.g., 5G (NR)). According to one embodiment, the electronic device (101) may change (or switch) an input voltage supplied to at least one power amplifier (PA) (the first PA (421), the second PA (422), and / or the third PA (423)) according to the type of transmission channel so as to reduce or minimize noise of audio data caused by a power difference (e.g., a difference in input voltage) between different types of transmission channels set for each slot. The transmission channels in the method (e.g., NR SA or / and NSA) of implementing 5G (NR) communication may include an uplink shared channel (PUSCH), a subcarrier spacing (SRS), and an uplink control channel (PUCCCH). The first type of transmission channel is an NR transmission channel set to a first power, which is a designated maximum power, and may include at least one of a PUSCH or an SRS. The second type of transmission channel is an NR transmission channel set to a second power that is lower by a designated value (e.g., 20 dBm) or more than the first power, and may include a PUCCH. The type of transmission channel may be set for each slot (e.g., 1 slot = 14 symbols), as illustrated in FIG. 6. For example, the slot time may be set to 0.5 ms based on 30 kHz of SRS. For example, as illustrated in FIG. 7, according to the switching time spec of the switch, considering the SCS 30 kHz Symbol Duration of 33.33 us with a Max 2.5 us, it can be seen that the time for VCC switching (e.g., within approximately 1 μs) is sufficient.For example, as shown in Fig. 8, when VCC is switched from VCCB to VCCA, the switching time is found to be approximately 0.4 μs in actual test results.

[0083] According to one embodiment, the electronic device (101) can change (e.g., VCC switching of FIG. 6) the input voltage (VCC) supplied to at least one amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) according to the type of transmission channel in the standalone mode (SA) of 5G communication (e.g., NR) using only one of the first power supply (VCC1) (e.g., 4 V) or the second power supply (VCC2) (e.g., 1 V). According to one embodiment, if the third power amplifier (e.g., ENDC OMH PA) (423) is set to LTE Tx, the electronic device (101) can change (or switch) the input voltage according to the type of transmission channel in the LTE SA mode in the same manner as in the SA mode of 5G communication (e.g., NR).

[0084] At least one communication processor according to one embodiment may be similar to or identical to the second communication processor (214) or the integrated communication processor (260) described in FIGS. 2A and 2B. At least one RFIC according to one embodiment may be similar to or identical to the second RFIC (224), the third RFIC (226), or the fourth RFIC (228) described in FIGS. 2A and 2B.

[0085] According to one embodiment, the power amplification module (420) may include a plurality of power amplifiers (a first PA (421), a second PA (422), a third PA (423), a fourth PA (424), a fifth PA (425), and / or a sixth PA (426)).

[0086] According to one embodiment, the first modulator (411) may be connected to a fourth power amplifier (e.g., LB PA) (424) and a sixth power amplifier (426) to supply a first power source (VCC1). The first modulator (411) may be selectively connected to at least one of the first power amplifier (e.g., n77 PA) (421), the second power amplifier (e.g., n79 PA) (422), and the third power amplifier (ENDC OMH PA) (423) via a switch (430) depending on a change in the type of a transmission channel to supply the first power source (VCC1).

[0087] According to one embodiment, the second modulator (412) may be connected to the fifth power amplifier (e.g., OMH PA (Main)) (425) and the sixth power amplifier (426) to supply the second power source (VCC2). The second modulator (412) may be selectively connected to at least one of the first power amplifier (e.g., n77 PA) (421), the second power amplifier (e.g., n79 PA) (422), or the third power amplifier (ENDC OMH PA) (423) via a switch (430) depending on a change in the type of the transmission channel to supply the second power source (VCC2).

[0088] According to one embodiment, the switch (430) may be configured to be included within or connected to the first power amplifier (e.g., n77 PA) (421). The switch (430) may have one end (e.g., an input end) connected to at least one of the first power amplifier (421), the second power amplifier (422), or the third power amplifier (423), and the other end (e.g., an output end) connected to the first modulator (411) or the second modulator (412). The switch (430) may be a single pole double throw (SPDT) relay or a single pole three throw (SP3T) relay.

[0089] According to one embodiment, the electronic device (101) can check a method of implementing 5G communication (e.g., NR SA mode or LTE SA mode) by at least one processor (e.g., processor (120) of FIG. 1 or communication processor (e.g., second communication processor (214) of FIG. 2A or integrated communication processor (260) of FIG. 2B). The electronic device (101) can check RCV (real clear voice) on / off status and check the electric field by the reception sensitivity (RSRP: reference signal received power). The electronic device (101) can identify the NR SA mode and RCV on status, and if the electric field by the reception sensitivity is a weak electric field or a strong electric field and the uplink or downlink transport block size is greater than a certain value, the electronic device (101) can perform an operation of changing (or switching) the input voltage according to the type of the transmission channel. If the RCV is off, it is difficult for the user to hear noise, so the input voltage is changed according to the type of the transmission channel. The operation can be performed only in the RCV on state. In the weak field, since the uplink shared physical channel (PUSCH), which is the first type of transmission channel, is set to the maximum power, a difference may occur between the power set for the uplink shared physical channel (PUSCH) and the power set for the uplink control physical channel (PUCCH), which is the second type of transmission channel. In the strong field, the PUSCH power may be set high in a large-capacity upload or download situation, and the power of other transmission channels may be set to a level similar to that of the PUCCH. Accordingly, the electronic device (101) can determine whether an operation of changing the input voltage is performed based on the transmission block size. Here, the transmission block size may be determined by the MCS, the modulation order, or the layer.As illustrated in FIG. 5a, in terms of downlink, the threshold for the transmission block size may be set to, for example, approximately 50,000 bytes. As illustrated in FIG. 5b, in terms of uplink, the threshold for the transmission block size may be set to, for example, approximately 30,000 bytes.

[0090] Referring to FIG. 9, according to one embodiment, when the electronic device (101) identifies the type of the transmission channel as the first type set to the first power, the electronic device (101) may connect at least one power amplifier (the first PA (421), the second PA (422), and / or the third PA (423)) to the first modulator (411) via the switch (430) to supply a first input voltage (e.g., 4 V) to the at least one power amplifier (the first PA (421), the second PA (422), and / or the third PA (423)). The transmission channel may be a channel set to transmit a transmission signal (Tx) in a communication method that implements 5G communication (NR).

[0091] According to one embodiment, the electronic device (101) may connect at least one power amplifier (the first PA (421), the second PA (422), and / or the third PA (423)) to the second modulator (412) via a switch (430) to supply a second input voltage (e.g., 1 V) lower than the first input voltage to at least one power amplifier (the first PA (421), the second PA (422), and / or the third PA (423)) based on the change of the type of the transmission channel to a second type set to a second power (e.g., extremely weak electric field power or 0 dBm) that is at least a designated value (e.g., approximately 20 dBm) lower than the first power (e.g., max power). According to one embodiment, when transmitting a signal using SRS in 3 slots, as illustrated in FIG. 9, the electronic device (101) supplies a first input voltage (e.g., 4 V) from the first modulator (411) to at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) by connecting at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) to the first modulator (411) as a first power source (VCC1) through the switch (430), and when the type of the transmission channel is changed to a second type of PUCCH in 4 slots, the electronic device (101) supplies at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) as a second power source (VCC1) through the switch (430). A second input voltage (e.g., 1 V) that is a relatively low voltage can be supplied to the amplifier (the first PA (421), the second PA (422) and / or the third PA (423)).

[0092] According to one embodiment, when a transmission channel is changed from a second type of transmission channel (e.g., PCUCH) to a first type of transmission channel (e.g., SRS) while the second modulator (412) and at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) are connected in the 7 slots thereafter, the electronic device may maintain the connection of the at least one amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) with the second modulator (412) through the switch (430), and supply a first input voltage (e.g., 4 V) from the second modulator (412) to the at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)).

[0093] According to one embodiment, the electronic device may connect the at least one amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) to the first modulator (411) via the switch (430) based on a change from a first type of transmission channel (e.g., SRS) to a second type of transmission channel (PUCCH) while the second modulator (412) and at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) are connected in the 8 slots thereafter, and supply a second input voltage (e.g., 1 V) from the first modulator (411) to the at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)). According to one embodiment, the electronic device (101) can change the modulator (e.g., VCC1 or VCC2) that supplies the changed voltage to change the input voltage when the type of the transmission channel is changed to PUCCH in slots 4 to 8, as illustrated in FIG. 9. The electronic device can improve call quality by minimizing (or reducing) the problem of noise occurring due to a sudden change in the input voltage (e.g., change from 1 V to 4 V or change from 4 V to 1 V) by changing the input voltage only with the first power source (VCC1) (e.g., first modulator (411)) in slots 4 to 8.

[0094] Again, referring to FIG. 9 , according to one embodiment, when the electronic device (101) changes from a first type of transmission channel (e.g., SRS) to a second type of transmission channel (e.g., PUCCH) in slot 14 while the second modulator (412) and at least one power amplifier (421, 422 and / or 423) are connected, the electronic device (101) may connect at least one amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) to the first modulator (411) via the switch (430) and supply a second input voltage (e.g., 1 V) from the first modulator (411) to the at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)).

[0095] According to one embodiment, when the transmission channel is changed to a first type of transmission channel (e.g., SUS) while the first modulator (411) and at least one amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) are connected in the 17 slot, the electronic device (101) can maintain the connection of the at least one amplifier (the first PA (421), the second PA (422) and / or the third PA (423)) with the first modulator (411) through the switch (430) and supply a first input voltage (e.g., 4 V) from the first modulator (411) to the at least one power amplifier (the first PA (421), the second PA (422) and / or the third PA (423)).

[0096] According to one embodiment, the electronic device (101) may connect at least one power amplifier (e.g., a first PA (421), a second PA (422), and / or a third PA (423)) via a switch (430) to a modulator (e.g., a power supply) connected to change (or switch) an input voltage when transmitting a transmission signal using a second type of transmission channel (PUCCH) to minimize the possibility of a switch damage problem occurring due to frequent input voltage changes (e.g., VCC switching).

[0097] According to one embodiment, the electronic device (101) changes (or switches) the input voltage to minimize the possibility of a burnout problem of a switch due to frequent input voltage changes (e.g., VCC switching), and then a modulator not connected to at least one power amplifier (the first PA (421), the second PA (422), and / or the third PA (423)) reduces the voltage stepwise in slot time units to prevent rapid discharge of a capacitor, and changes (or switches) the input voltage only when transmitting a signal using a PUCCH for which a relatively low voltage (e.g., the second input voltage) is set, to prevent rapid charging of the capacitor. For example, the electronic device (101) can stepwise reduce the input voltage of VCC1 (e.g., the first modulator (411)) from slots 4 to 6 or slots 14 to 16, as illustrated in FIG. 9, and the electronic device (101) can stepwise reduce the input voltage of VCC2 (e.g., the second modulator (412)) from slots 8 to 12 or slots 18 and 19, as illustrated in FIG. 9.
