Meanwhile, a plurality of antennas connected to the 4G wireless communication module 111 and the 5G wireless communication module 112 may be disposed on the side of the terminal. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

Meanwhile, a plurality of antennas disposed on the side of the terminal may be implemented with four or more antennas to support MIMO. In addition, when the 5G wireless communication module 112 operates in a millimeter wave (mmWave) band, as each of the plurality of antennas is implemented as an array antenna, a plurality of array antennas may be disposed in an electronic device.

The terminal body is provided with a terminal power supply unit 190 (refer to FIG. 1A) for supplying power to the electronic device 100. The terminal power supply unit 190 may include a battery 191 that is built into the terminal body or configured to be detachable from the outside of the terminal body.

Hereinafter, a structure of a multiplex transmission system according to the present invention and an electronic device having the same, in particular, a power amplifier in a heterogeneous radio system and embodiments related to an electronic device having the same will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

2 shows a configuration of a wireless communication unit of an electronic device operable in a plurality of wireless communication systems according to the present invention. Referring to FIG. 2, the electronic device includes a first power amplifier 210, a second power amplifier 220, and an RFIC 250. In addition, the electronic device may further include a modem 270 and an application processor 280. Here, the modem (Modem, 270) and the application processor (AP, 280) are physically implemented in one chip, and may be implemented in a logical and functional separate form. However, the present invention is not limited thereto and may be implemented in the form of a physically separated chip according to an application.

Meanwhile, the electronic device includes a plurality of low noise amplifiers (LNAs) 261 to 264 in the receiver. Here, the first power amplifier 210, the second power amplifier 220, the RFIC 250, and the plurality of low-noise amplifiers 261 to 264 are all operable in the first communication system and the second communication system. In this case, the first communication system and the second communication system may be a 4G communication system and a 5G communication system, respectively.

As shown in FIG. 2, the RFIC 250 may be configured as a 4G/5G integrated type, but is not limited thereto and may be configured as a 4G/5G separate type according to an application. When the RFIC 250 is configured as a 4G/5G integrated type, it is advantageous in terms of synchronization between 4G/5G circuits and has an advantage that control signaling by the modem 270 can be simplified.

Meanwhile, when the RFIC 250 is configured as a 4G/5G separate type, it may be referred to as a 4G RFIC and a 5G RFIC, respectively. In particular, when the 5G band and the 4G band have a large difference in bands, such as when the 5G band is configured as a millimeter wave band, the RFIC 250 may be configured as a 4G/5G separate type. In this way, when the RFIC 250 is configured as a 4G/5G separate type, there is an advantage that RF characteristics can be optimized for each of the 4G band and the 5G band.

Meanwhile, even when the RFIC 250 is configured as a 4G/5G separate type, the 4G RFIC and the 5G RFIC may be logically and functionally separated, and may be physically implemented on a single chip.

On the other hand, the application processor (AP, 280) is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP, 280) may control the operation of each component of the electronic device through the modem 270.

For example, the application processor (AP, 280) may control the modem 270 through a power management IC (PMIC) for low power operation of an electronic device. Accordingly, the modem 270 may operate the power circuit of the transmitter and the receiver through the RFIC 250 in a low power mode.

In this regard, when it is determined that the electronic device is in an idle mode, the application processor (AP) 280 may control the RFIC 250 through the modem 270 as follows. For example, if the electronic device is in an idle mode, at least one of the first and second power amplifiers 110 and 120 operates in a low power mode or is turned off through the modem 270 through the RFIC. 250 can be controlled.

According to another embodiment, when the electronic device is in a low power mode, the application processor (AP) 280 may control the modem 270 to provide wireless communication capable of low power communication. For example, when an electronic device is connected to a plurality of entities among a 4G base station, a 5G base station, and an access point, the application processor (AP) 280 may control the modem 270 to enable wireless communication with the lowest power. Accordingly, even if the throughput is slightly sacrificed, the application processor (AP) 280 may control the modem 270 and the RFIC 250 to perform short-range communication using only the short-range communication module 113.

According to another embodiment, when the remaining battery power of the electronic device is equal to or greater than a threshold, the modem 270 may be controlled to select an optimal wireless interface. For example, the application processor (AP, 280) may control the modem 270 to receive data through both the 4G base station and the 5G base station according to the remaining battery capacity and available radio resource information. In this case, the application processor (AP) 280 may receive information on the remaining battery capacity from the PMIC and information on available radio resources from the modem 270. Accordingly, if the remaining battery capacity and available radio resources are sufficient, the application processor (AP, 280) may control the modem 270 and the RFIC 250 to receive data through both the 4G base station and the 5G base station.

Meanwhile, in the multi-transceiving system of FIG. 2, the transmitting unit and the receiving unit of each radio system may be integrated into a single transmitting/receiving unit. Accordingly, there is an advantage in that a circuit part that integrates two types of system signals can be removed from the RF front-end.

In addition, since the front-end components can be controlled by the integrated transceiver, the front-end components can be integrated more efficiently than when the transmission/reception system is separated for each communication system.

In addition, when the communication systems are separated, it is impossible to control other communication systems as necessary, or because a system delay is increased due to this, it is impossible to efficiently allocate resources. On the other hand, the multiple transmission/reception system as shown in FIG. 2 has the advantage of enabling efficient resource allocation since it is possible to control other communication systems as needed, and thereby minimize system delay.

Meanwhile, the first power amplifier 210 and the second power amplifier 220 may operate in at least one of the first and second communication systems. In this regard, when the 5G communication system operates in the 4G band or the Sub6 band, the first and second power amplifiers 220 can operate in both the first and second communication systems.

On the other hand, when the 5G communication system operates in the millimeter wave (mmWave) band, one of the first and second power amplifiers 210 and 220 may operate in the 4G band and the other may operate in the millimeter wave band. have.

On the other hand, by integrating the transmitting and receiving unit and the receiving unit, it is possible to implement two different wireless communication systems with one antenna using a transmission/reception combined antenna. In this case, 4x4 MIMO can be implemented using 4 antennas as shown in FIG. 2. In this case, 4x4 DL MIMO may be performed through downlink (DL).

Meanwhile, if the 5G band is the Sub6 band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in both the 4G band and the 5G band. On the other hand, if the 5G band is a millimeter wave (mmWave) band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in any one of the 4G band and the 5G band. In this case, if the 5G band is a millimeter wave (mmWave) band, each of a plurality of separate antennas may be configured as an array antenna in the millimeter wave band.

Meanwhile, 2x2 MIMO can be implemented using two antennas connected to the first power amplifier 210 and the second power amplifier 220 among the four antennas. In this case, 2x2 UL MIMO (2 Tx) may be performed through uplink (UL). Alternatively, it is not limited to 2x2 UL MIMO, and may be implemented with 1 Tx or 4 Tx. In this case, when the 5G communication system is implemented with 1 Tx, only one of the first and second power amplifiers 210 and 220 needs to operate in the 5G band. Meanwhile, when the 5G communication system is implemented with 4Tx, an additional power amplifier operating in the 5G band may be further provided. Alternatively, a transmission signal may be branched in each of one or two transmission paths, and the branched transmission signal may be connected to a plurality of antennas.

On the other hand, a switch-type splitter or power divider is built into the RFIC corresponding to the RFIC 250, so that separate parts do not need to be placed outside, thereby improving component mounting performance. I can. Specifically, it is possible to select the transmission unit (TX) of two different communication systems by using a single pole double throw (SPDT) type switch inside the RFIC corresponding to the control unit 250.

In addition, an electronic device capable of operating in a plurality of wireless communication systems according to the present invention may further include a duplexer 231, a filter 232, and a switch 233.

The duplexer 231 is configured to separate signals in the transmission band and the reception band from each other. In this case, a signal of a transmission band transmitted through the first and second power amplifiers 210 and 220 may be applied to the antennas ANT1 and ANT4 through the first output port of the duplexer 231. On the other hand, signals in the reception band received through the antennas ANT1 and ANT4 may be received by the low noise amplifiers 261 and 264 through the second output port of the duplexer 231.

The filter 232 may be configured to pass a signal in a transmission band or a reception band and block signals in the remaining bands. In this case, the filter 232 may include a transmission filter connected to the first output port of the duplexer 231 and a reception filter connected to the second output port of the duplexer 231. Alternatively, the filter 232 may be configured to pass only the signal of the transmission band or only the signal of the reception band according to the control signal.

The switch 233 is configured to transmit only either a transmission signal or a reception signal. In an embodiment of the present invention, the switch 233 may be configured in the form of a single pole double throw (SPDT) to separate a transmission signal and a reception signal in a time division multiplexing (TDD) scheme. In this case, the transmission signal and the reception signal are signals of the same frequency band, and accordingly, the duplexer 231 may be implemented in the form of a circulator.

Meanwhile, in another embodiment of the present invention, the switch 233 is applicable to a frequency division multiplexing (FDD) scheme. In this case, the switch 233 may be configured in the form of a Double Pole Double Throw (DPDT) so as to connect or block a transmission signal and a reception signal, respectively. On the other hand, since the transmission signal and the reception signal can be separated by the duplexer 231, the switch 233 is not necessarily required.

Meanwhile, the electronic device according to the present invention may further include a modem 270 corresponding to a control unit. In this case, the RFIC 250 and the modem 270 may be referred to as a first control unit (or a first processor) and a second control unit (a second processor), respectively. Meanwhile, the RFIC 250 and the modem 270 may be implemented as physically separate circuits. Alternatively, the RFIC 250 and the modem 270 may be physically logically or functionally divided into one circuit.

The modem 270 may perform control and signal processing for transmission and reception of signals through different communication systems through the RFIC 250. The modem 270 may be obtained through control information received from a 4G base station and/or a 5G base station. Here, the control information may be received through a physical downlink control channel (PDCCH), but is not limited thereto.

The modem 270 may control the RFIC 250 to transmit and/or receive signals through the first communication system and/or the second communication system at a specific time and frequency resource. Accordingly, the RFIC 250 may control transmission circuits including the first and second power amplifiers 210 and 220 to transmit a 4G signal or a 5G signal in a specific time period. In addition, the RFIC 250 may control receiving circuits including the first to fourth low noise amplifiers 261 to 264 to receive 4G signals or 5G signals in a specific time period.

Meanwhile, the memory 170 of the electronic device 100 according to an embodiment of the present invention may include a plurality of extension codebooks corresponding to a plurality of different peripheral devices in addition to a basic codebook including basic code words. Each of the extended codebooks includes at least one code word, and the code words are information including a phase angle and a gain of an antenna, and at least one of the phase angle and gain may be different information. Alternatively, the extended codebook may further include information different from information included in the basic codebook, or some values of information included in the basic codebook may be different from each other.

Meanwhile, the plurality of extension codebooks may include extension codebooks directly corresponding to a specific peripheral device. Or, it may include extended codebooks that can be universally applied when a specific condition is satisfied.

Table 1 below shows examples of these extension codebooks.

Referring to Table 1, when the state of the electronic device 100 is a default state, that is, a default state, a default codebook may be applied. In addition, in the case of a specific peripheral device such as a dual screen device or a mmW boost esternal module, an extension codebook (DS_mmW_ant_codebook or Ex_bst_module_codebook) corresponding to the peripheral device may correspond.

In addition, any one extension codebook corresponding to a combination of a plurality of peripheral devices mounted on the electronic device 100 may be included. For example, as shown in [Table 1], an extended codebook (DS_module_1_codebook) corresponding to a combination of a dual screen device and an added mmW module may be included.

Meanwhile, in the case of a peripheral device that cannot be specified, such as a general external case, an extension codebook that can be universally applied may correspond. In this case, the outer case may be classified into different types of chairman cases according to an effect on the electric field, and may correspond to different extension codebooks, respectively.

For example, in the case of an external case (external case 1) in which the effect on the electric field is less than or equal to a preset level, an extended codebook (default codebook + offset correction) including an offset correction value for at least one of the code words of the basic codebook may be corresponding. I can.

On the other hand, in the case of an external case (external case 2) in which the effect on the electric field exceeds a preset level, an extended codebook (Case2_codebook) including at least one new code word different from the code words of the basic codebook may be corresponded.

Status information	Codebook
Default state	Default codebook
External Case 1	Default codebook + offset correction
Exterior Case 2	Case2_codebook
Dual Screen Only	DS_mmW_ant_codebook
Dual Screen W / added mmW module	DS_module_1_codebook
mmW boost external module	Ex_bst_module_codebook

Accordingly, the electronic device 100 according to an embodiment of the present invention may perform beamforming again by adding code words included in the extended codebook corresponding to the installed peripheral device or the combination of the mounted peripheral devices to the basic codebook. I can. Meanwhile, when the installed peripheral device is not specified, beamforming may be performed again by adding code words included in one of the universal extension codebooks to the basic codebook based on the identification result of the peripheral device.

Specific operations and functions of the electronic device 100 according to the present invention will be reviewed below.

Modem 270 of the electronic device 100 according to the embodiment of the present invention, when the electronic device 100 is not equipped with a peripheral device, based on the code words of the basic codebook, the appropriate phase and gain for each antenna. By setting a value and controlling a beam former, a beam may be formed according to the set phase and gain values. Accordingly, when a peripheral device is not mounted, a beam according to a phase angle and a gain according to the code words of the basic codebook may be formed.

Meanwhile, when at least one peripheral device is mounted on the electronic device 100, the modem 270 may identify the peripheral device mounted on the electronic device 100 and detect extended codebooks corresponding to the identified peripheral device. . In addition, the phase angle and gain of the antennas may be set based on the detected code words of the extended codebook. In addition, by controlling the beam former, a beam may be formed according to the set phase and gain values. Accordingly, the direction and pattern of the beam may be determined according to code words of the extended codebook.

Accordingly, phase angles and gains different from the code words of the basic codebook may be set in the antennas, and accordingly, a beam having a direction and pattern different from that of a beam formed according to the basic codebook may be generated. That is, electric field distortion caused by mounting of the peripheral device may be reduced by changing the direction and pattern in which the beam is formed according to code words included in the extended codebook.

3 is a flowchart illustrating an operation process of performing beamforming characterization again according to an attached peripheral device in the electronic device 100 according to the embodiment of the present invention.

Referring to FIG. 3, when at least one peripheral device is mounted on the electronic device 100, the modem 270 of the electronic device 100 according to an embodiment of the present invention may identify the attached peripheral device ( S300). For example, the peripheral device may be a device that can be connected to the electronic device 100 through a connection terminal formed in advance when mounted, such as a dongle mounted on the electronic device 100 or an earphone.

In this case, the modem 270 may identify the attached peripheral device based on identification information received from the peripheral device through the connection terminal or whether the connection terminal is connected. Alternatively, the modem 270 identifies a peripheral device installed in the electronic device 100 through a preset sensor, or based on the feedback power of the transmission (Tx) signal (the feedback strength of the transmission signal). It is also possible to identify peripheral devices installed in 100). Hereinafter, a more detailed operation process of the modem 270 for identifying a peripheral device mounted on an electronic device will be described in more detail with reference to FIG. 6.

In step S300, when a peripheral device mounted on the electronic device 100 is identified, the modem 270 may detect an extended codebook corresponding to the identified peripheral device (S302). Here, if there are a plurality of peripheral devices mounted on the electronic device 100, the modem 270 may detect any one extension codebook corresponding to a combination in which the plurality of peripheral devices are mounted.

When the extended codebook corresponding to the peripheral device identified in step S302 is detected, the modem 270 may add code words of the detected extended codebook to the basic codebook (S304). Accordingly, in addition to the code words included in the basic codebook, a new codebook further including code words of the extended codebook may be formed.

Then, the modem 270 may control the beamformer so that the beamforming is re-characterized based on the codebook to which the code words of the extended codebook are added (S306). That is, the modem 270 may further include the added code words to form a beam. Accordingly, the modem 270 may form a beam having a direction and pattern different from the direction and pattern in which the beam is formed according to the basic codebook 400.

Accordingly, the modem 270 may form a beam in a direction and pattern that can minimize electric field distortion caused by mounting of the peripheral device, and reduce electric field distortion caused by the mounted peripheral device. In addition, the modem 270 may operate re-characterized beamforming to perform wireless communication in a state in which electric field distortion caused by mounting of the peripheral device is minimized (S308).

Meanwhile, when the peripheral device is unmounted, the modem 270 may delete code words of the added extended codebook from the basic codebook. Accordingly, when the peripheral device is unmounted, the modem 270 may control the beam former so that the beam is formed according to the basic codebook again. That is, the code words of the extended codebook may be activated (added to the basic codebook) or deactivated (deleted from the basic codebook) based on whether or not a peripheral device is installed in the electronic device 100.

4 and 5 are exemplary diagrams for explaining an example in which code words corresponding to installed peripheral devices are added in an electronic device according to an embodiment of the present invention.

First, referring to FIG. 4, FIG. 4A shows an example of a basic codebook 400. In addition, FIG. 4B shows an example of the extended codebook 450 detected in step S302 of FIG. 3.

4A and 4B, the basic codebook 400 and the extended codebook 450 each include information on antenna information (module, antenna group, antenna type, etc.) and phase angle. Although not shown, information on the gain of each antenna may be further included.

In addition, the code words of the basic codebook 400 and the extended codebook 450 may each include information corresponding to different beam identification information (IDentification). Therefore, even when the code words of the extended codebook 450 are further added to the basic codebook 400, each code word can be classified through the beam identification information.

Meanwhile, FIG. 5 shows an example in which the codebook 500 in which the code words of the extended codebook 450 detected in the step S302 of FIG. 3 are added to the basic codebook 400 is formed as the step S304 of FIG. 3 proceeds. There is.

As shown in FIG. 5, the new codebook 500 may include both the code words of the basic codebook 400 and the code words of the extended codebook 450, and accordingly, a phase angle different from the code words of the basic codebook. And gains can be set on the antennas.

Accordingly, the modem 270 may form a beam in a direction and pattern different from the direction and pattern in which the beam is formed according to the basic codebook 400. That is, by changing the direction and pattern in which the beam is formed according to the code words included in the extended codebook, electric field distortion caused by mounting of the peripheral device may be reduced.

Meanwhile, FIG. 6 is a flowchart illustrating in more detail an operation process of identifying an attached peripheral device in the electronic device 100 according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the modem 270 of the electronic device 100 according to an embodiment of the present invention detects that a peripheral device is mounted on the electronic device 100 when a preset identification condition is satisfied, and is installed. Peripheral devices can be detected. For example, when a connection or connection of a peripheral device is detected by a preset connection terminal or sensor, the modem 270 may detect that the peripheral device is mounted on the electronic device 100. Alternatively, the modem 270 may detect a feedback power of a transmission (Tx) signal, and when the loss of the feedback power is greater than or equal to a preset level, it may detect that a peripheral device is installed in the electronic device 100. In addition, peripheral devices mounted on the electronic device 100 may be identified through the process of FIG. 6.

First, the modem 270 may detect whether there is a peripheral device connected to the electronic device 100 in communication (S600). In addition, when there is a communication-connected peripheral device, it may be identified whether the communication-connected peripheral device is a device mounted on the electronic device 100 based on identification information received from the peripheral device (S602). Then, the modem 270 may proceed to step S302 of FIG. 3 to detect an extended codebook corresponding to the identified peripheral device.

For example, in the case of a peripheral device that is equipped with a communication unit and is connected through wireless communication with the electronic device 100, such as a dual screen case, in steps S600 and S602, through the wireless communication It can be identified based on the received identification information. In this case, even if the communication-connected peripheral device is not a device mounted on the electronic device 100 (for example, a smart watch or HMD, etc.), the modem 270 uses the identification information received in step S602 to the electronic device 100 It can be identified that it is not a device mounted on.

On the other hand, when there is no peripheral device connected to the electronic device 100 through communication, or when a peripheral device mounted on the electronic device 100 is not identified through the received identification information, the modem 270 is the electronic device 100 It may be detected whether there is a peripheral device detected through at least one sensor provided in (S604). In addition, when there is a peripheral device detected through the at least one sensor, the peripheral device mounted on the electronic device 100 may be identified based on a detection result of the sensor. Then, the modem 270 may proceed to step S302 of FIG. 3 to detect an extended codebook corresponding to the identified peripheral device.

For example, the at least one sensor may be a magnetic sensor disposed around the display unit 151 in the electronic device 100. In this case, when a preset case (for example, a specific case in which a magnet having a preset magnetic force is embedded) is mounted on the electronic device 100, the magnetic sensor indicates that the specific case is mounted based on the magnetic force of the specific case. It can be detected and identified that the mounted case is the specific case.

Meanwhile, when identification is impossible even through the at least one sensor, the modem 270 may detect a loss amount of the feedback power of the transmission signal (S608). For example, the modem 270 may compare the transmitted power of the transmission signal with the feedback power of the transmission signal and detect the difference as the loss amount. In addition, the installed peripheral device may be identified based on the detected loss amount (S610).

Meanwhile, as shown in the identification result in step S610, when the installed peripheral device is not specified, the modem 270 may detect any one of the plurality of extended codebooks based on the detected loss amount. In this case, in step S302 of FIG. 3, different extension codebooks may be detected according to the detected loss amount.

For example, if the detected loss amount is less than a preset threshold value, it is detected that the first extended codebook corresponds to the installed peripheral device, and if the detected loss amount exceeds a preset threshold value, the second extended codebook is It may be detected as corresponding to the mounted peripheral device. In this case, the first and second extension codebooks may be general-purpose extension codebooks including different code words.

Meanwhile, according to the above description, it has been mentioned that the peripheral device mounted on the electronic device 100 may have a separate external antenna. In this case, the modem 270 of the electronic device 100 according to an embodiment of the present invention detects mounting of a peripheral device having the external antenna, and detects and detects an extended codebook including code words related to the external antenna. The beam former can be controlled to re-characterize the beamforming according to the expanded codebook. 7 shows an example of this case.

First, referring to FIG. 7, the electronic device 100 according to an embodiment of the present invention includes a separate display unit 720 (hereinafter, referred to as a second display unit) and an external antenna 770 as shown in the top view of FIG. 7. The dual screen case 700 may be mounted. In this case, the electronic device 100 may be inserted and mounted in the mounting frame 710 formed in the dual screen case 700, and a terminal formed in the mounting frame 710 or a preset wireless communication method (e.g., Bluetooth communication) Method), the dual screen case 700 and communication may be connected.

When the dual screen case 700 is mounted as described above, the electric fields of the first antenna 750 and the second antenna 760 of the electronic device 100 may be distorted due to the mounting of the dual screen case 700. .

Among them, the first antenna 750 is spaced apart from the second display unit 720 of the dual screen case 700 to some extent, and transmits a beam in a direction opposite to the direction in which the second display unit 720 is disposed. Therefore, the communication performance 750 may be deteriorated according to the dielectric constant of the mounting frame 710 of the dual screen case 700.

Meanwhile, in the case of the second antenna 760 disposed on the side of the second display unit 720 of the dual screen case 700, the second display unit 720 is disposed adjacent to each other, so that the dielectric constant of the second display unit 720 is Due to the communication performance 762 may be greatly deteriorated. In particular, when the second display unit 720 includes a metal material, the communication performance 762 of the second antenna 760 may be further deteriorated.

Meanwhile, even if the dual screen case 700 includes the external antenna 770, in the case of the basic codebook, information on the external antenna 770, that is, identification information, group information, and antenna information of the external antenna , Phase angle information, gain information, and the like are not included, so that the beam cannot be formed using the external antenna 770. Therefore, wireless communication through the external antenna 770 is not performed.

In this state, the modem 270 of the electronic device 100 according to an embodiment of the present invention receives identification information received from the dual screen case 700 and detects an extended codebook corresponding to the dual screen case 700. can do. In this case, the detected extended codebook may include identification information, group information, antenna information, phase angle information, and gain information related to the external antenna 770 as code words.

Therefore, when the code words included in the extended codebook are added to the basic codebook, the modem 270 provides the external antenna 770 as well as the first antenna 750 and the second antenna 760. Beamforming characterization can be performed. Accordingly, as shown in the lower drawing of FIG. 7, a beam may be formed from the external antenna 770 as well as the first antenna 750 and the second antenna 760.

Meanwhile, beams formed by the first antenna 750 and the second antenna 760 may also have a different direction or a different pattern from a previously formed beam according to code words included in the extended codebook. Then, the modem 270 detects the communication performance according to the beam formed from the first antenna 750 and the second antenna 760, and the external antenna 770, and any one antenna having the best communication performance Wireless communication can be performed through.

Meanwhile, according to the above description, it has been mentioned that the extended codebook may further include information different from information included in the basic codebook. In this case, the additional information may include a weight of a power corresponding to a vector (beam) of a specific phase angle.

FIG. 8 is an exemplary diagram illustrating an example in which additional code words further include power weights in the electronic device 100 according to the embodiment of the present invention in this case.

Referring to FIG. 8, first, FIG. 8A shows an example of an extension codebook 850 corresponding to a peripheral device mounted on the electronic device 100. The extended codebook 850 may include values of power weights (Power_Wgt, 852) according to each beam, that is, a vector corresponding to each phase angle, as shown in FIG. 8A.

Here, the power weight (Power_Wgt, 852) may be information on power and output strength to be increased or decreased for a vector corresponding to each beam identification information ID.

It can mean an uncovered state. For example, the open state may be divided into a 90 degree open state, a 180 degree open state, and a 360 degree open state, and the dual screen case 700 is a second state in any one of the open states through a fixing means. The state of the display unit 720 may be fixed.

Meanwhile, the controller of the dual screen case 700 may detect a state in which the second display unit 720 is fixed through the fixing means or at least one preset sensor. In addition, one of the extended codebooks may be detected based on the detected open state of the second display unit 720.

To this end, the memory 170 of the electronic device 100 according to an embodiment of the present invention may store extended codebooks corresponding to each of the open states of the second display unit 720 of the dual screen case 700. Here, the same extended codebook corresponds to the case where the open state of the second display unit 720 is 360 degrees and the state where the display unit 151 (hereinafter referred to as the first display unit) of the electronic device 100 is covered, that is, a closed state. I can.

Meanwhile, extension codebooks corresponding to each of the open states of the second display unit 720 may each include different code words. Accordingly, when the open state of the second display unit 720 is changed, the modem 270 adds code words of different extension codebooks to the basic codebook according to the changed open state of the second display unit 720 to create a new codebook. Can be generated. In addition, by controlling the beam former based on the generated codebook, a beam according to the added code words may be formed.

Meanwhile, in the above description, it has been described as an example that an extension codebook corresponding to a peripheral device in which the memory 170 of the electronic device 100 according to an embodiment of the present invention is mounted is included, but the extension codebook is Of course, it may be provided. For example, when the above-described dual screen case 700 is mounted on the electronic device 100, the modem 270 may receive an extended codebook from the dual screen case 700, and the code words of the provided extended codebook are basically used. You can create a new codebook by adding it to the codebook.
