The present invention relates to an electronic device supporting 5G communication, and more particularly, to a Non BC (Beam Correspondence) type electronic device having different RX antennas and TX antennas.

Recently, wireless communication systems using LTE communication technology have been commercialized for electronic devices, providing various services. In addition, in the future, wireless communication systems using 5G communication technology are expected to be commercialized and provide various services. Meanwhile, some of the LTE frequency bands may be allocated to provide 5G communication services.

The 5G network communication method requires higher spectral efficiency and higher data rate than the conventional communication methods (LTE, 4G). Further, a method of using spatial multiplexing to cover a wider range using a plurality of antennas (hereinafter, referred to as multiple antennas) and a method of using a beam (beam forming) formed through the plurality of antennas has emerged. This spatial multiplexing technique has characteristics that are resistant to fading and noise, and since beamforming minimizes the influence of reflected waves due to multipaths, high spectral efficiency and data rate required in 5G can be achieved.

In the case of such a beamforming method, it refers to a method in which a transmitting side and a receiving side form a beam having a high antenna gain by synthesizing signals transmitted from multiple antennas. Accordingly, when the transmission (TX) side beam and the reception (RX) side beam match each other, high transmission power and high reception gain may be obtained. To this end, the electronic device receives a reference signal (RS) signal from each of the antennas forming the respective beams, and enables data to be received through a beam having the best RS signal reception performance.

A second camera 121b may be disposed on the rear surface of the terminal body. In this case, the second camera 121b has a photographing direction substantially opposite to the first camera 121a.

The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may be arranged in a matrix format. Such a camera may be referred to as an array camera. When the second camera 121b is configured as an array camera, an image may be photographed in various ways using a plurality of lenses, and an image of better quality may be obtained.

The flash 124 may be disposed adjacent to the second camera 121b. When a subject is photographed by the second camera 121b, the flash 124 illuminates light toward the subject.

A second sound output unit 152b may be additionally disposed on the terminal body. The second sound output unit 152b may implement a stereo function together with the first sound output unit 152a, and may be used to implement a speakerphone mode during a call.

At least one antenna for wireless communication may be provided in the terminal body. The antenna may be embedded in the terminal body or may be formed in a case. 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, since each of the plurality of antennas is implemented as an array antenna, a plurality of array antennas may be disposed in the mobile terminal.

The terminal body is provided with a terminal power supply unit 190 (refer to FIG. 1A) for supplying power to the mobile terminal 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 a mobile terminal having the same, in particular, a power amplifier in a heterogeneous radio system and embodiments related to a mobile terminal 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 a mobile terminal capable of operating in a plurality of wireless communication systems according to the present invention. Referring to FIG. 2, the mobile terminal includes a first power amplifier 210, a second power amplifier 220, and an RFIC 250. In addition, the mobile terminal may further include a modem 270 and an application processor 280. Here, the modem (Modem, 270) and the application processor (AP, 280) may be physically implemented in one chip, and may be implemented in a logically and functionally separated 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 mobile terminal 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 in 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.

Meanwhile, the application processor (AP) 280 is configured to control the operation of each component of the mobile terminal. Specifically, the application processor (AP, 280) may control the operation of each component of the mobile terminal 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 the mobile terminal. 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 mobile terminal 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 mobile terminal is in a standby mode (idle mode), at least one of the first and second power amplifiers (110, 120) to operate in a low power mode or off (off) RFIC through the modem 270 250 can be controlled.

According to another embodiment, when the mobile terminal 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 a mobile terminal 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 level of the mobile terminal exceeds a threshold value, 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 parts can be controlled by the integrated transmission/reception unit, the front end parts 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, a mobile terminal 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 mobile terminal according to the present invention may further include a modem 270 corresponding to the 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, specific operations and functions of the mobile terminal according to the present invention equipped with the multiple transmission/reception system as shown in FIG. 2 will be reviewed below.

3 is a block diagram illustrating a structure of a wireless communication unit of an electronic device having a Non BC structure according to an embodiment of the present invention.

As shown in FIG. 3, the wireless communication unit of an electronic device having a non-BC structure includes an RX RFIC 300, the plurality of low-noise amplifiers 310 connected to the RX RFIC 300, a duplexer, and a plurality of RX. It may include an antenna. In addition, the TX RFIC 350, a plurality of low power amplifiers 360 connected to the TX RFIC 350, a plurality of low noise amplifiers 370, and a plurality of connected to the low power amplifier 360 and the low noise amplifier 370. It may include a switch 380, a duplexer, and a plurality of TX antennas. In addition, a modem 270 and an application processor (AP) 280 may be further included. Here, the modem 270 and the A 280 may be implemented on one chip or may be implemented in the form of separate chips.

Meanwhile, the RX RFIC 300 and the TX RFIC 350 may be configured as a 4G/5G integrated type or may be configured as a 4G/5G separate type. For example, when the 5G band and the 4G band have a large difference in bands, such as when the 5G band is composed of a millimeter wave band, the RX RFIC 300 and the TX RFIC 350 may be configured as separate 4G/5G types. In the following description, for convenience of explanation, the RX RFIC 300 and the TX RFIC 350 are configured in an integrated 4G/5G type as an example.

Referring to FIG. 3, each of the RX antennas may be connected to a duplexer that separates signals of a reception band. In addition, each duplexer may be connected to a low noise amplifier (LNA) 310, respectively. In addition, a filter formed to pass only a signal in a reception band may be included between each duplexer and each low noise amplifier 310. Accordingly, signals in the reception band received through the RX antennas may be amplified by the low noise amplifier 310 through the output port of the duplexer and input to the RX RFIC 300.

Meanwhile, the TX antennas may be connected to a duplexer that separates signals in the transmission band and the reception band. In addition, each duplexer may be connected to a switch 380 configured to transmit only one of a transmission signal or a reception signal. Here, a filter configured to pass a signal in a transmission band or a reception band and block signals in the other bands may be included between each duplexer and each switch 380.

The switch 233 may be formed to separate a transmission signal or a reception signal according to a time division multiplexing (TDD) scheme. For example, it may be configured in the form of Single Pole Double Throw (SPDT).

The switch 380 may be synchronized with the timing according to the time division multiplexing under the control of the modem 270. In more detail, the switch 380 may be controlled to separate a received signal during a reception (RX) time according to the time division multiplexing (TDD) and a transmission signal during a transmission (TX) time. That is, the switch 380 is controlled by the modem 270 so that the signal received through the TX antenna is input to the TX RFIC 350 at the reception (RX) time according to the time division multiplexing, to the low noise amplifier 370. Switch the path to the connected path, and switch the path to the path connected to the low power amplifier 370 so that the amplified signal through the low power amplifier 360 is transmitted through the TX antenna at the transmission (TX) time according to the time division multiplexing. I can.

Meanwhile, a signal received through TX antennas at the transmission (TX) time may be control data received from a base station. The control data may include a reference signal (RS). In this case, the modem 270 may receive control data received through each of the TX antennas separately from the data received from the RX antennas through the TX RFIC 350, and the signal strength of the received control data or Effective Isotropic Radiated Power (EIRP) calculated from the received control data may be calculated. In addition, the TX antenna having the highest signal strength or EIRP may be detected based on the calculated result.

Meanwhile, when the transmission (TX) time according to the time division multiplexing is reached, the modem 270 may use the beam of the TX antenna detected to have the highest signal strength or EIRP for data transmission. That is, data can be transmitted to the base station through the TX antenna detected to have the highest signal strength or EIRP. Accordingly, the electronic device according to the embodiment of the present invention is Accordingly, data can be transmitted to the base station through the TX beam having the highest transmission efficiency.

Meanwhile, signals received from the TX antennas may be control signals for detecting a TX antenna suitable for data transmission. Therefore, the low-noise amplifier 370 connected to the TX RFIC 350 is for identification and amplification of the received control signal, and is an amplifier having a lower amplification degree than the amplification degree of the low-noise amplifier 310 connected to the RX RFIC 300. I can.

Meanwhile, in the above description, a configuration in which the separated RX RFIC 300 and TX RFIC 350 are connected to the modem 270, respectively, has been described, but the RX RFIC 300 and TX RFIC 350 are one RFIC. Of course it may be. In this case, the RX RFIC 300 and the TX RFIC 350 are logically and functionally separated, and may be physically implemented on one chip.

4 is an exemplary diagram illustrating an example in which a TX beam and an RX beam are formed in an electronic device having a non BC structure according to an embodiment of the present invention.

Referring to FIG. 4, in the case of an electronic device having a Non BC structure, an example in which a plurality of different Rx beams (kRx) and Tx beams (kTx) are used is illustrated. As shown in FIG. 4, since the electronic device having the Non BC structure uses separate RX and TX antennas, respectively, as shown in FIG. 4, the RX beams and TX beams formed in the electronic device may be formed differently. have.

Meanwhile, FIG. 5 is a conceptual diagram illustrating a subframe structure according to a TDD scheme in 5G communication.

Referring to FIG. 5, a region marked with DL represents a downlink control region, and an region marked with UL represents an uplink control region. In addition, the data area may be used for downlink data transmission or uplink data transmission. Each area can be divided into a short time GP (Gap). As shown in FIG. 5, in the case of 5G communication, DL transmission and UL transmission are sequentially performed within a subframe.

As described above, in the case of 5G communication, transmission and reception of data may be sequentially performed alternately according to time division multiplexing (TDD). Accordingly, UL (Uplink) and DL (Down Link) transmitting data are performed in different time zones.

Meanwhile, in the case of the electronic device having the Non BC structure according to the embodiment of the present invention shown in FIG. 3 described above, since the TX antennas have a reception path independent from the RX antennas, not only the RX antennas but also the RX antennas at the same time. It is possible to receive signals from the TX antenna as well.

6 is a flowchart illustrating an operation process in which a TX antenna is selected during RX time in an electronic device having a Non BC structure according to an embodiment of the present invention.

First, in the case of a down link (DL) transmission time, that is, an RX time, the modem 270 of the electronic device 100 according to an embodiment of the present invention may receive data from the base station through at least one RX antenna. In this case, the modem 270 may control each of the switches 300 to receive a signal from each TX antenna. In this case, each of the TX antennas may receive a control signal received from the base station (S600). Accordingly, the modem 270 may receive RS (Reference Signal) signals transmitted from the base station through each TX antenna during the RX time period, apart from data received from the RX antenna.

Meanwhile, in step S600, when RS signals are received from each of the TX antennas, the modem 270 may select a TX antenna to be used for data transmission based on the received RS signal (S602).

For example, the modem 270 may select any one TX antenna based on the signal strength of the RS signals received in step S602. For example, the modem 270 may select a TX antenna having the greatest strength of the received RS signal. Alternatively, the modem 270 may calculate the EIRPs by reflecting the amplitude deviation () and the directivity angle deviation () for the RS signals received for each TX antenna. In addition, a TX antenna to be used for data transmission may be selected based on the calculated EIRPs.

As described above, when the transmission (TX) side beam and the reception (RX) side beam match each other, the highest transmission power and high reception gain are obtained, so that the reception strength of the RS signal is detected the highest or the EIRP is the highest. The highly calculated TX antenna may be an antenna that forms a beam that matches the transmission-side beam of the base station. Therefore, it is highly likely that the transmission (TX) beam formed from the TX antenna with the highest reception strength of the RS signal or the highest EIRP calculated is matched with the reception (RX) beam of the base station, and accordingly, the modem 270 May select a TX antenna with the highest reception strength of the RS signal or the highest EIRP calculated as the TX antenna to be used for data transmission.

Meanwhile, the modem 270 may determine whether the UL (Up Link) transmission time, that is, the TX time, has been reached (S604). In addition, if the TX time has been reached, data may be transmitted to the base station based on the antenna selected in step S602 (S606).

Meanwhile, in step S606, the modem 270 may deactivate the RX antennas during the TX time. And when the RX time is reached again, the RX antennas can be reactivated. Meanwhile, when the RX time is reached again, the modem 270 may repeat the process described in FIG. 6. Accordingly, the modem 270 may control each of the switches 300 to receive an RS signal from each TX antenna.

Accordingly, the electronic device of the Non BC structure according to the embodiment of the present invention may be deactivated during the TX time as in the case of the conventional non BC electronic device in the case of RX antennas, but in the case of TX antennas, the electronic device of the conventional Non BC structure Unlike a device, it operates in an active state even during RX time and can receive an RS signal from the base station. In addition, the electronic device of the Non BC structure according to an embodiment of the present invention exchanges separate signals with the base station during the TX time by determining the TX antenna to transmit data based on the RS signals received from each TX antenna during the RX time. There is an advantage in that data can be transmitted through TX data, which has the highest transmission efficiency of actual data, even without the process of doing so.

On the other hand, when analyzing RS signals received from all TX antennas, it may be the most accurate, but the computational amount may be large. Accordingly, the modem 270 may reduce the number of RS signals to be analyzed by using the RX antenna used for data reception in order to reduce the amount of computation.

For example, the modem 270 may detect an RX antenna having the highest data reception efficiency when the reception (RX) time according to the time division multiplexing method comes. In addition, data can be received from the base station through the detected RX antenna.

Meanwhile, the modem 270 may select at least TX antennas to analyze the RS signal based on the RX antenna used for data reception. And by analyzing only the RS signals received from the selected TX antennas, it is possible to reduce the amount of computation according to the analysis of the RS signals.

As described above, when the transmitting (TX) side beam and the receiving (RX) side beam are matched with each other, it has the highest transmission power and high reception gain. Therefore, the RX antenna with the highest reception efficiency matches the transmission beam of the base station. It may be an antenna that forms a beam. Therefore, in the case of the RX antenna with the highest reception efficiency, that is, the TX antenna disposed around the RX antenna used for data reception or oriented in a direction similar to the RX antenna used for data reception, the reception (RX) beam of the base station This is because it is highly likely to match.

To this end, the memory 170 of an electronic device according to an embodiment of the present invention may include a table including a plurality of TX antennas corresponding to each RX antenna, as shown in Table 1 below.

Beam pair	Rx beam #	Candidate Tx Beam #
One	#One	#1, #2, #3
2	#2	#2, #3, #4
...	...	...
K Rx	#K Rx	..., #K Tx -1, #K Tx

In this case, the modem 270 selects a TX antenna group corresponding to the RX antenna used for data reception based on the table stored in the memory 170, and RS signals received from TX antennas included in the selected TX antenna group. Can be analyzed and any one TX antenna can be selected according to the analysis result.

7 is a flowchart illustrating an operation process of selecting a plurality of TX antennas through a table including TX antennas corresponding to each RX antenna and receiving RS signals through the selected plurality of TX antennas.

Referring to FIG. 7, in the case of down link (DL) transmission time, that is, RX time, the modem 270 of the electronic device 100 according to an embodiment of the present invention may proceed to step S600 of FIG. 6. In addition, when step S600 of FIG. 6 proceeds, the modem 270 may first select a plurality of TX antennas based on the RX antennas currently used for data reception through the table (S700).

For example, if the table is as shown in [Table 1] and the RX antenna currently used for data reception is the 1st RX antenna (1# RX antenna), the modem 270 is 1, 2, And 3 TX antennas (1#, 2#, 3# TX antennas) may be selected.

Meanwhile, when a plurality of TX antennas are selected based on the RX antennas in step S700, the modem 270 may receive an RS signal from each of the selected plurality of TX antennas (S702). Here, the RS signal may be a signal broadcast from the base station. For example, if data is received from a base station through RX antenna #1 in Table 1, while data is received through RX antenna #1, modem 270 is #1, #2, and #3. The RS signal may be received through a TX antenna.

Meanwhile, in step S702, when RS signals are received from the selected plurality of TX antennas, the modem 270 proceeds to step S602 of FIG. 6 to analyze the RS signals received from the plurality of TX antennas selected through the table. According to the result, any one TX antenna may be selected as a TX antenna to transmit data. In this case, any one of some of the TX antennas selected through the process described in FIG. 7 may be selected as a TX antenna to transmit data.

Meanwhile, in the above description, in the case of an electronic device according to an embodiment of the present invention having a non BC structure, a configuration in which an RS signal is received from a base station during TX time and an optimal TX antenna is selected has been described. However, this is only an example to aid in the description of the present invention, of course, the present invention is not limited thereto.

For example, in the case of an electronic device having a non-BC structure capable of receiving data from a base station during the RX time, as in the present invention, it is of course possible to further receive not only the RS signal but also various other control signals during the RX time. For example, the TX antennas may receive signals from other base stations adjacent to each other during the RX time, and based on the received signals, a list of base stations, that is, cells, located around the electronic device may be formed, or a searched 5G base station may be added. Of course. In this case, it goes without saying that the electronic device can use the list of cells or information on the added 5G base station when moving or registering for 5G communication.

Meanwhile, in the above description, it has been described that the modem 270 controls all operation processes, but this series of processes is not the modem 270, but the controller 180 that performs overall control of the AP 280 or the electronic device 100. Of course, it can also be performed by ).

The present invention described above can be implemented as a computer-readable code on a medium on which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAM, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc. There is also a carrier wave (for example, transmission over the Internet) also includes the implementation of the form. In addition, the computer may include the control unit 180 of the terminal. Therefore, the detailed description above should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
