Description

5G communication relay device

The present invention relates to a 5G communication relay device. More specifically, it relates to a 5G CPE (Customer Premises Equipment) for transmitting a 5G radio signal between a 5G base station and an electronic device and a control method thereof.

Electronic devices can be divided into mobile/portable terminals and stationary terminals depending on whether they can be moved. Again, electronic devices can be divided into handheld terminals and vehicle mounted terminals depending on whether the user can directly carry them.

The functions of electronic devices are diversifying. For example, there are functions of data and voice communication, taking pictures and videos through a camera, recording voice, playing music files through a speaker system, and outputting images or videos to the display unit. Some terminals add an electronic game play function or perform a multimedia player function. In particular, recent mobile terminals can receive multicast signals providing visual content such as broadcasting and video or television programs.

In order to support and increase the function of the electronic device, it may be considered to improve the structural part and/or the software part of the terminal.

In addition to the above attempts, wireless communication systems using LTE communication technology have recently been commercialized in 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.

In this regard, the mobile terminal may be configured to provide 5G communication services in various frequency bands. Recently, attempts have been made to provide a 5G communication service using a Sub6 band below 6GHz band. However, in the future, it is expected to provide 5G communication service using millimeter wave (mmWave) band in addition to Sub6 band for faster data rate.

Therefore, a 5G communication relay device, that is, a 5G CPE, should be placed adjacent to the window area of the building. In particular, since the 5G radio signal from the 5G base station has directivity, it is necessary to place the 5G CPE at a specific angle in the direction of the 5G radio signal at a specific location.

Therefore, when 5G CPE is installed in an indoor space within a building, it is necessary to arrange the 5G CPE at an optimal position and tilt angle. However, there is a problem in that the user or the installer cannot know whether the 5G CPE is placed at an optimal position and angle within the indoor space.

The 5G CPE 500 includes a control unit (processor) 510, a transceiver 520, a second transmission/reception unit 530, and a display unit 540. Meanwhile, the electronic device 100 includes a transmission/reception unit 110, an output unit 150, and a control unit 180 corresponding to a wireless communication unit.

More specifically, among the components, the transmission/reception unit 110 is between the electronic device 100 and the wireless communication system, between the electronic device 100 and other electronic devices 100, or between the electronic device 100 and an external server. It may include one or more modules that enable wireless communication between. In addition, the transmission/reception unit 110 may include one or more modules that connect the electronic device 100 to one or more networks. Here, the one or more networks may be, for example, a 4G communication network and a 5G communication network.

The transceiver 110 may include at least one of a 4G wireless communication module, a 5G wireless communication module, a short-range communication module, and a location information module.

The 4G wireless communication module can transmit and receive 4G base stations and 4G signals through a 4G mobile communication network. At this time, the 4G wireless communication module may transmit one or more 4G transmission signals to the 4G base station. In addition, the 4G wireless communication module may receive one or more 4G received signals from the 4G base station.

In this regard, an uplink (UL) multi-input multi-output (MIMO) may be performed by a plurality of 4G transmission signals transmitted to the 4G base station. In addition, a downlink (DL) multi-input multiple output (MIMO) may be performed by a plurality of 4G reception signals received from a 4G base station.

The 5G wireless communication module can transmit and receive 5G base stations and 5G signals through a 5G mobile communication network. Here, the 4G base station and the 5G base station may have a non-stand-alone (NSA) structure. For example, the 4G base station and the 5G base station may have a co-located structure disposed at the same location within a cell. Alternatively, the 5G base station may be disposed in a separate location from the 4G base station in a stand-alone (SA) structure.

The 5G wireless communication module can transmit and receive 5G base stations and 5G signals through a 5G mobile communication network. In this case, the 5G wireless communication module may transmit one or more 5G transmission signals to the 5G base station. In addition, the 5G wireless communication module may receive one or more 5G received signals from the 5G base station.

In this case, the 5G frequency band may use the same band as the 4G frequency band, and this may be referred to as LTE re-farming. On the other hand, as the 5G frequency band, the Sub6 band, which is a band below 6GHz, may be used.

On the other hand, a millimeter wave (mmWave) band may be used as a 5G frequency band to perform broadband high-speed communication. When a millimeter wave (mmWave) band is used, the electronic device 100 may perform beam forming to expand communication coverage with a base station.

Meanwhile, regardless of the 5G frequency band, in a 5G communication system, a greater number of multiple input multiple outputs (MIMO) may be supported to improve transmission speed. In this regard, uplink (UL) MIMO may be performed by a plurality of 5G transmission signals transmitted to the 5G base station. In addition, downlink (DL) MIMO may be performed by a plurality of 5G reception signals received from the 5G base station.

Meanwhile, the transceiver 110 may be in a dual connectivity (DC) state with a 4G base station and a 5G base station through a 4G wireless communication module and a 5G wireless communication module. In this way, the dual connection between the 4G base station and the 5G base station may be referred to as EN-DC (EUTRAN NR DC). Here, EUTRAN is an Evolved Universal Telecommunication Radio Access Network, which means 4G wireless communication system, and NR is New Radio, which means 5G wireless communication system.

On the other hand, if the 4G base station and the 5G base station have a co-located structure, it is possible to improve throughput through inter-CA (Carrier Aggregation). Therefore, with the 4G base station and the 5G base station In the EN-DC state, 4G and 5G signals can be simultaneously received through the 4G wireless communication module and the 5G wireless communication module.

The short range communication module is for short range communication, and includes Bluetooth™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and Near Field (NFC).

Wireless communication between networks in which the electronic device 100 or an external server is located may be supported. The local area wireless communication network may be a wireless personal area network (Wireless Personal Area Networks).

Meanwhile, short-range communication between electronic devices may be performed using a 4G wireless communication module and a 5G wireless communication module. In an embodiment, short-range communication may be performed between electronic devices through a device-to-device (D2D) method without passing through a base station.

On the other hand, carrier aggregation (CA) may be performed using at least one of a 4G wireless communication module and a 5G wireless communication module, and a Wi-Fi communication module for transmission speed improvement and communication system convergence. In this regard, 4G + WiFi carrier aggregation (CA) may be performed using a 4G wireless communication module and a Wi-Fi communication module. Alternatively, 5G + WiFi carrier aggregation (CA) may be performed using a 5G wireless communication module and a Wi-Fi communication module.

The location information module is a module for obtaining a location (or current location) of an electronic device, and representative examples thereof include a GPS (Global Positioning System) module or a WiFi (Wireless Fidelity) module. For example, if the electronic device utilizes a GPS module, the electronic device may acquire the location of the electronic device using a signal transmitted from a GPS satellite. As another example, when the electronic device utilizes the Wi-Fi module, the location of the electronic device may be obtained based on information of the Wi-Fi module and a wireless access point (AP) that transmits or receives a wireless signal. If necessary, the location information module may perform any function among other modules of the transmission/reception unit 110 in order to obtain data on the location of the electronic device as a substitute or additionally. The location information module is a module used to obtain the location (or current location) of the electronic device, and is not limited to a module that directly calculates or obtains the location of the electronic device.

Specifically, if the electronic device utilizes the 5G wireless communication module, the electronic device may acquire the location of the electronic device based on information of the 5G wireless communication module and the 5G base station transmitting or receiving a wireless signal. In particular, since the 5G base station in the mmWave band is deployed in a small cell having a narrow coverage, it is advantageous to obtain the location of the electronic device.

The output unit 150 is for generating output related to visual, auditory or tactile sense, and may include at least one of a display unit, an audio output unit, a hap tip module, and a light output unit. The display unit forms a layered structure with the touch sensor or is integrally formed, thereby implementing a touch screen. Such a touch screen may function as a user input unit providing an input interface between the electronic device 100 and a user, and may provide an output interface between the electronic device 100 and the user.

Furthermore, in order to drive the application program, the controller 180 may operate by combining at least two or more of the components included in the electronic device 100 with each other.

Meanwhile, four or more antennas disposed on the side of the terminal may be implemented to support MIMO. In addition, when the 5G wireless communication module 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 electronic device.

On the other hand, the 5G communication system according to the present invention can be configured to include a 4G base station 600 and a 5G base station 700. In this regard, the 5G CPE 500 may receive a 5G radio signal from the 5G base station 700 and relay it to the electronic device 100. In addition, the 5G CPE 500 may receive a 5G radio signal from the electronic device 100 and transmit it to the 5G base station 700. In this regard, in a 5G non-stand-alone (NSA) structure, the 5G CPE 500 can maintain a dual connection state (EN-DC) with the 4G base station 600 and the 5G base station 700. In addition, in the 5G NSA structure, the 5G CPE 500 may transfer some control information to both the 4G base station 600 and the 5G base station 700.

Referring to FIG. 1, a transceiver 110 corresponding to a wireless communication unit includes a 5G wireless communication module and a short-range communication module.

To this end, when the 5G communication relay device 500 performs a TX disable process, the controller 180 may transmit the user data and control data to the 5G communication relay device 500. 110) can be controlled.

Meanwhile, when cell search is started, the 5G base station 700 does not allocate time and frequency resources for transmitting user data and control data to the electronic device 100 and the 5G CPE 500. However, the 5G base station 700 transfers a first radio resource to the

electronic device

Here, the transmission restriction signaling may be transmitted to the 5G communication relay device 500 through a second wireless interface different from the 5G wireless interface. Specifically, the second wireless interface may be the aforementioned short-range wireless communication interface, for example, a Bluetooth or a Wi-Fi interface.

Specifically, even when a first radio resource for transmission of control data is allocated, the controller 180 may transmit transmission restriction signaling to the 5G communication relay device 500 so as not to transmit control data. Here, the transmission restriction signaling is a message that restricts transmission of control data until RRC connection and measurement report.

In addition, even when a second radio resource for user data transmission is allocated, the controller 180 may transmit the second transmission restriction signaling to the 5G communication relay device 500 so as not to transmit user data. Here, the second transmission restriction signaling is a message for restricting transmission of control data until the end of the test mode.

With regard to the 5G CPE, the transceiver 520 is configured to transmit and receive radio signals. Specifically, the transceiver 520 is configured to transmit and receive 5G NR signals, and may transmit and receive 4G LTE signals.

Specifically, the second transceiver 530 may perform a short-range communication with the paired electronic device 100 by performing a pairing process for short-range communication with the peripheral electronic device 100.

The control unit (processor) 510 is connected to the transmission/reception unit 520 and is configured to provide a radio signal received from the base station to the electronic device 100. According to the present invention, the control unit (processor) 510 can control so that a radio signal is not transmitted through the transmission/reception unit 520 when a cell search is initiated in a test mode. have.

The display unit 540 may be configured to display 5G NR signal quality and status received from the base station. In addition, the display unit 540 may display information guiding a user or an installation manager who installs the 5G CPE to arrange the 5G CPE at an optimal position and angle.

On the other hand, the 5G base station 700 is a 5G communication relay device, that is, when the 5G CEP 500 is operated in a test mode and a cell search is initiated, the 5G CEP 500 is It can be controlled not to transmit signals, including data and control data.

To this end, when cell search is initiated, the 5G base station 700 does not allocate time and frequency resources for transmitting user data and control data to the electronic device 100 and the 5G CPE 500. However, the 5G base station 700 transfers a first radio resource to the

electronic device

2 is a diagram illustrating a configuration of a wireless communication unit of an electronic device or a 5G communication relay device capable of operating in a plurality of wireless communication systems according to the present invention. Here, the 5G communication relay device according to the present invention is a device that transmits a 5G radio signal between a base station and an electronic device, that is, a 5G UE. In this regard, a 5G communication relay device, that is, a 5G CPE (Customer Premises Equipment), may be provided with a plurality of array antennas ANT1 to ANT4 to optimally transmit and receive 5G radio signals in a specific direction. In addition, the 5G communication relay apparatus may include a power and phase controller 230 to control the beam direction of each of the array antennas ANT1 to ANT4. In this regard, the power and phase controller 230 may control a magnitude and a phase of a signal applied to each antenna element of each of the array antennas ANT1 to ANT4. In this regard, the transmission/reception unit 520 of FIG. 1 may correspond to the RFIC 250 in the plurality of array antennas ANT1 to ANT4 of FIG. 2. In addition, the control unit 510 of FIG. 1 may correspond to the modem 400 and the AP 450 of FIG. 2.

Referring to FIG. 2, the electronic device or 5G communication relay device further 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 400 and an application processor 500. Here, the modem 400 and the application processor AP 450 may be physically implemented in one chip, and may be logically and functionally separated. However, the present invention is not limited thereto and may be implemented in the form of physically separated chips depending on the application.

Meanwhile, an electronic device or a 5G communication relay device includes a plurality of low noise amplifiers (LNAs) 410 to 440 in a receiver. Here, the first power amplifier 210, the second power amplifier 220, the controller 250, and the plurality of low noise amplifiers 310 to 340 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 400 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 are logically and functionally separated, and physically, it is possible to be implemented in one chip.

Meanwhile, the application processor (AP, 450) is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP, 450) may control the operation of each component of the electronic device through the modem 400.

For example, the modem 400 may be controlled through a power management IC (PMIC) for low power operation of an electronic device. Accordingly, the modem 400 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 450 may control the RFIC 250 through the modem 300 as follows. For example, if the electronic device is in the 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 300 through the RFIC. 250 can be controlled.

According to another embodiment, when the electronic device is in a low battery mode, the application processor (AP, 450) may control the modem 300 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) 450 may control the modem 400 to enable wireless communication with the lowest power. Accordingly, even though the throughput is slightly sacrificed, the application processor (AP, 450) may control the modem 400 and the RFIC 250 to perform short-range communication using only the short-range communication module.

According to another embodiment, when the remaining battery power of the electronic device is equal to or greater than a threshold, the modem 400 may be controlled to select an optimal wireless interface. For example, the application processor (AP, 450) may control the modem 400 to receive through both the 4G base station and the 5G base station according to the remaining battery capacity and available radio resource information. At this time, the application processor (AP, 450) may receive the remaining battery level information from the PMIC, the available radio resource information from the modem 400. Accordingly, if the remaining battery capacity and available radio resources are sufficient, the application processor (AP, 450) may control the modem 400 and the RFIC 250 to receive reception 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 one transmitting and receiving unit. Accordingly, there is an advantage in that a circuit part integrating 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 separated for each communication system, 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.

Meanwhile, by integrating the transmitting and receiving unit and the receiving unit, it is possible to implement two different wireless communication systems with a single antenna using a transmitting and receiving antenna. At this time, 4x4 MIMO can be implemented using four 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, the signal of the transmission band transmitted through the first and

second power amplifiers

210 and 220 is 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 are received by the

low noise amplifiers

310 and 340 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) so as 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 400 corresponding to a control unit. In this case, the RFIC 250 and the modem 400 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 400 may be implemented as physically separate circuits. Alternatively, the RFIC 250 and the modem 400 may be physically divided into one circuit logically or functionally.

The modem 400 may perform control and signal processing for transmission and reception of signals through different communication systems through the RFIC 250. The modem 400 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 400 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. Further, the RFIC 250 may control receiving circuits including the first to fourth low noise amplifiers 310 to 340 to receive a 4G signal or a 5G signal in a specific time period.

Meanwhile, a 5G communication relay device, that is, a 5G CPE (Customer Premises Equipment) that transmits a 5G radio signal to an electronic device equipped with a multiple transmission/reception system as shown in FIG. 2, and a control method thereof will be described.

In this regard, since the speed of the existing broadband network is low and enormous cost is incurred to install a new giga network, 5G CPE is required. In addition, even if a new subscriber is created, the distance for each household is long, so it may incur a lot of cost for laying cables and for engineers to visit and install them. In order to solve this problem, it is desirable to provide 5G communication services indoors through 5G CPE.

Network operators who want to create new business after 4G LTE are competitively building 5G networks. However, it is difficult to create new business only with the advantage that 5G networks are faster than 4G networks.

Accordingly, operators may consider a method of wirelessly supplying the Internet to each home using a high-speed communication network, instead of providing Internet service through a conventional cable.

However, compared to the frequencies used in existing LTE or 3G, 5G uses a very high frequency band as a high-speed communication network. Therefore, the 5G radio signal causes large RF loss due to nearby objects such as buildings and trees.

Operators may want to provide 5G CPE, and users do self-install so that engineers do not visit or lay separate cables. However, due to the characteristics of 5G NR radio, there is a problem in that it is difficult to determine the optimal installation angle and location of 5G CPE for installation.

Accordingly, the 5G communication relay device, that is, the 5G CPE according to the present invention may be implemented with the following technical features in order to solve the above-described problem.

1) We propose an indoor CPE using an antenna that supports high power class, that is, Power class 1 (eg, 48dBm).

2) Extend 5G service coverage of 5G CPE by using a directional antenna and beamforming method.

3) When using a directional antenna, apply a method to cover the issue of limited angular regions providing 5G services.

4) When using a high frequency, apply safety measures to prevent harmful effects on the human body.

A specific method for implementing the technical features of the 5G communication relay device, that is, 5G CPE according to the present invention is as follows.

1) Since 5G radio signals with high frequency characteristics have strong linearity, it is difficult to search for an area where signals are captured indoors. Therefore, proper positioning of the 5G CPE is required to receive and capture signals indoors.

2) Since the wavelength is short according to the high-frequency characteristics and the reach of the signal is short, beamforming must be performed in the direction of the base station, that is, in the optimal signal direction, in order to satisfy 5G reception performance. Therefore, a tilting operation is required to search for an optimal signal direction between the 5G CPE and the base station.

In this regard, FIG. 3 is a conceptual diagram for a method of installing a 5G communication relay device, that is, a 5G CPE according to the present invention. Meanwhile, FIGS. 4A and 4B are flowcharts illustrating a control operation performed in a 5G communication relay device, that is, a 5G CPE according to the present invention.

Referring to FIG. 3A, 5G New Radio (NR) signal strength may be measured. In this regard, referring to FIG. 4A, a test mode may be performed (S110) while performing 5G NR measurement. On the other hand, as the test mode is performed (S110), a TX disable procedure may be performed (S120). In this regard, while the test mode is performed (S110) and the TX disable procedure is performed (S120), the 5G NR base station is not yet connected. Accordingly, as shown in FIG. 4A, it is possible to indicate that “No NR Connection” is through an electronic device corresponding to the test tool. Here, No NR Connection means that there is no radio resource control (RRC) connection state.

On the other hand, this test mode is mainly performed during the initial installation of 5G CPE. However, the present invention is not limited thereto, and may be performed when the user is notified of the change in the propagation environment and the user selects a test mode. While the TX disable procedure is performed (S120), the 5G CPE does not perform any signal transmission procedure to the base station or the peripheral electronic device. However, control signal transmission may be performed exceptionally for NR measurement report according to 5G NR signal measurement.

If the 5G NR signal strength does not exceed a certain level, the 5G CPE can be moved to another location indoors as shown in FIG. 3(b). As described above, when the 5G NR signal strength is higher than a certain level at another location indoors, an NR connection is performed. In this regard, referring to FIG. 4A, NR measurement according to the 5G NR signal measurement may be performed (S130) even while the TX disable procedure is performed (S120). In this regard, as NR measurement is performed (S130), an NR connection may be made. Accordingly, as shown in FIG. 4A, it is possible to indicate that “NR Connection” is through an electronic device corresponding to the test tool. Here, NR Connection means a radio resource control (RRC) connection state.

When the NR connection is established, appropriate altitude detection may be performed through a tilting operation as shown in FIG. 3(c). In addition to the mechanical tilting operation, the tilting operation may also be performed through an electric tilting operation through beam forming for fine angle or height adjustment.

Referring to FIG. 3C, the 5G CPE may be rotated by a predetermined angle in a horizontal direction (S141). For example, the 5G CPE can be rotated within an azimuth angle of ±30 degrees in the horizontal direction. However, the azimuth rotation angle is not limited thereto and may be an arbitrary rotation angle depending on the application.

In addition, referring to FIG. 3(c), the 5G CPE may be rotated by a predetermined angle in a vertical direction (S142). For example, the 5G CPE can be rotated within a range of an elevation angle of ±30 degrees in a vertical direction. However, the elevation angle rotation angle is not limited thereto, and may be an arbitrary rotation angle depending on the application, and may be a value different from the azimuth rotation angle. In addition, instead of rotating the 5G CPE by a certain angle in the vertical direction, the height of the installation device in which the 5G CPE is installed can be adjusted. Therefore, the 5G CPE can be arranged in the optimal signal reception direction in the horizontal and vertical directions. Accordingly, the 5G CPE may turn off the test mode, transmit a signal received from the base station to the electronic device, and transmit the signal received from the electronic device to the base station.

Therefore, the 5G CPE control operation according to the present invention can be performed in two steps as follows.

Step 1: Apply the Tx disable algorithm to ensure the safety of users or installers during installation

Step 2: Apply an algorithm that quickly detects which direction is the optimal tilt direction during installation

In this regard, the application of the Tx disable algorithm is performed while the test mode is performed (S110) and the TX disable procedure is performed (S120). Meanwhile, even when the NR connection is established, the Tx disable algorithm may be performed until the test mode is terminated. Meanwhile, the application of an algorithm for quickly detecting which direction is the optimal tilt direction during installation is performed through a horizontal rotation step (S141) and a vertical rotation step (S142).

Meanwhile, FIG. 5 is a flowchart illustrating an internal configuration of a 5G CPE and a 5G CPE control operation with an electronic device according to the present invention.

Referring to FIG. 5, a test tool is an electronic device that performs 5G communication with a base station through 5G CPE. Meanwhile, BT is a wireless interface for performing short-range communication between a 5G CPE and an electronic device, and may be, for example, Bluetooth. However, it is not limited to Bluetooth and may be any short-range communication wireless interface such as Wi-Fi or Zigbee. Meanwhile, the RF/Protocol corresponds to a transmission/reception unit of a 5G CPE, and a control operation may be performed by a control unit (processor) of the 5G CPE. In addition, the LED is provided in the 5G CPE, and can display the installation status and 5G signal quality of the 5G CPE.

Meanwhile, referring to FIG. 1, a 5G CPE 500 includes a control unit (processor) 510, a transceiver 520, a second transmission/reception unit 530, and a display unit 540. Meanwhile, the electronic device 100 includes a transmission/reception unit 110, an output unit 150, and a control unit 180 corresponding to a wireless communication unit.

In addition, the 5G communication system according to the present invention can be configured to include a 4G base station 600 and a 5G base station 700. In this regard, the 5G CPE 500 may receive a 5G radio signal from the 5G base station 700 and relay it to the electronic device 100. In addition, the 5G CPE 500 may receive a 5G radio signal from the electronic device 100 and transmit it to the 5G base station 700. In this regard, in a 5G non-stand-alone (NSA) structure, the 5G CPE 500 can maintain a dual connection state (EN-DC) with the 4G base station 600 and the 5G base station 700. In addition, in the 5G NSA structure, the 5G CPE 500 may transfer some control information to both the 4G base station 600 and the 5G base station 700.

electronic device

1, 3 to 5, the 5G CPE control operation according to the present invention may be performed in two steps as follows.

Therefore, since the 5G CPE according to the present invention uses a 5G signal of a high frequency band, a safety method is applied so that no harmful effect to the human body occurs during installation. Specifically, the 5G CPE control operation according to the present invention is to prevent the use of the Tx function during positioning, rotation, and tilting operations of the 5G CPE.

Referring to FIG. 1, a test tool corresponds to an electronic device 100. Meanwhile, the RF/Protocol may correspond to a transmission/reception unit or a control unit of a 5G CPE. For convenience of explanation, RF/Protocol is referred to as corresponding to the controller 510 of the 5G CPE. Meanwhile, BT refers to a second transmission/reception unit 530 of a 5G CPE that provides a second wireless interface for performing short-range communication with the electronic device 100. In addition, the LED refers to the installation state of the 5G CPE and the 5G signal quality as a display unit 540.

The control unit 510 of the 5G CPE may control the LTE base station to be in an LTE connection state through activation of a communication function. In the LTE connection state, NR measurement can be performed on a received signal received from an NR base station. In this regard, NR measurement may be performed even during the 5G NR Disable process (S120). Also, the NR measurement may be performed during the optimal Tilt control process (S140).

Meanwhile, when a user input for installing a 5G CPE is received (eg, Button On), the controller 510 of the 5G CPE may perform a test mode (S110). In addition, the controller 510 may control to be paired with the electronic device 100 through the second transceiver 530 when entering the test mode (ie, determining that the test mode is). For pairing with the electronic device 100 in the test mode, the nearby electronic device may be recognized through an advertising process with the nearby electronic device.

Regarding the 5G NR Disable process (S120), the controller 510 disables TX so that the radio signal is not transmitted through the transceiver 520 when a specific control signal is received from the 5G base station or in an RRC connection state. Execute the process.

Regarding the optimal tilt control process (S140), the controller 510 may search for an optimal direction of a signal received from a 5G base station in a horizontal direction and/or a vertical direction. Accordingly, the control unit 510 may perform one of a TX enable procedure (S150), a tilting procedure, and a reinstallation procedure based on the received signal quality from the 5G base station. Accordingly, when the received signal quality is good, the control unit 510 may indicate through the display unit 540 that the 5G CPE can be installed at a corresponding location. That is, the controller 510 may transmit information related to whether or not the 5G CPE can be installed at a corresponding location or an NR status to the display unit 540. Accordingly, the display unit 540 may display the NR status as Red, Yellow, Green, or the like, respectively. For example, if the LED is green, it indicates that the 5G signal strength is in a good state, and the 5G CPE can be installed normally at that location. On the other hand, if the LED is yellow, it indicates that the 5G signal strength is in a normal state, and installation is impossible unless the 5G CPE is tilted optimally in the horizontal and/or vertical directions. On the other hand, when the LED is displayed as red, it indicates that the 5G signal strength is in a weak state, and installation is impossible unless the 5G CPE is moved to another location.

When the TX enable procedure (S150) is performed, the controller 510 accesses the 5G network through a ping operation to the 5G network and ends the test mode. In this regard, when the PDN (Packet Data Network) attachment is completed, the controller 510 may terminate the test mode and transmit user data. Accordingly, the 5G CPE is connected to both the 5G base station and the 5G network.

As described above, when the test mode is performed (S110), the second transmission/reception unit 530 may perform a pairing operation with the electronic device 100. When pairing with the electronic device 100 is made, the second transceiving unit 530 may transmit the received signal quality, for example, Reference Signal Received Power (RSRP) to the electronic device 100. Meanwhile, when the test mode is terminated, information transfer between the electronic device 100 and the 5G CPE may be terminated.

Meanwhile, FIG. 6A shows a flowchart of a method for controlling positioning and tilting of a 5G CPE according to the present invention. 5 and 6A, a method for controlling positioning and tilting of a 5G CPE may be performed by the controller 510 based on a signal received from a 5G base station through a transceiver. In this regard, the positioning and tilting control method of the 5G CPE may be performed by a mechanical method or an electrical method.

Referring to FIG. 6A, the controller 510 may perform 5G NR measurement (S130) at a corresponding location. If it is determined that attachment to the 5G network is not possible according to the 5G NR measurement (S130), the LED may be displayed in red. If it is determined that such a situation as the RRC connection failure is permanent, position control (S101) may be performed to position the 5G CPE to a location other than the corresponding location. In this regard, the 5G CPE may autonomously perform position control (S101) within the movable range. Alternatively, the 5G CPE may indicate that the position control (S101) is required through a display unit such as an LED or through a peripheral electronic device such as a user terminal.

On the other hand, according to the received signal quality through 5G NR measurement (S130), for example, RSRP, horizontal rotation (tilt) control (S140) and/or vertical rotation (tilt) control (S150) may be performed. In this regard, operations of the horizontal rotation (tilt) control (S140) and/or the vertical rotation (tilt) control (S150) may correspond to horizontal rotation (tilt) and/or vertical rotation (tilt), respectively.

In this regard, if the quality of the received signal through the 5G NR measurement (S130) is less than or equal to the threshold, the horizontal rotation (tilt) control (S141) may be performed. If the received signal quality through the horizontal rotation (tilt) control (S141) is less than or equal to the threshold, the vertical rotation (tilt) control (S142) may be performed. In this regard, the threshold, which is the quality of the received signal, may correspond to 3 level. Here, the 3 level indicates that the 5G signal strength in which the LED is displayed as Green is in a good state, and that the 5G CPE can be installed normally at the corresponding location.

In this regard, the number of antennas in the horizontal direction of the array antennas in the 5G CPE may be set to be greater than the number of antennas in the vertical direction. Accordingly, the antenna beam can be precisely adjusted in the horizontal direction and the antenna beam can be adjusted again in the vertical direction. In this regard, if the received signal quality is greater than or equal to a threshold value through the horizontal rotation (tilt) control S140, there is an advantage that it is no longer necessary to perform the vertical rotation (tilt) control S150. Therefore, there is an advantage in that it is possible to improve the mechanical stability of the 5G CPE by not performing vertical rotation (tilt) of the 5G CPE.

Accordingly, if the received signal quality at the corresponding position and angle is greater than or equal to the threshold, it is determined as a strong electric field state, and an adjustment procedure such as tilt can be stopped. In addition, through the horizontal rotation (tilt) control (S141), if the received signal quality is greater than or equal to a threshold, it is determined as a strong electric field state, and an adjustment procedure such as tilt may be stopped. In addition, through the vertical rotation (tilt) control (S142), if the received signal quality is greater than or equal to a threshold, it is determined as a strong electric field state, and an adjustment procedure such as tilt may be stopped.

On the other hand, even through the vertical rotation (tilt) control (S142), if the received signal quality is less than the threshold, it may be determined as a weak electric field state. Accordingly, the LED is displayed in yellow to indicate that the 5G signal strength is in a normal state, and installation is impossible unless the 5G CPE is tilted optimally in the horizontal and/or vertical directions. On the other hand, according to the 5G signal strength, the LED is displayed in red to indicate that the 5G signal strength is in a weak state, and installation is impossible unless the 5G CPE is moved to another location. Specifically, when the received signal quality is less than the first threshold and equal to or greater than the second threshold (2 level), the tilting procedure may be performed. On the other hand, if the received signal quality is less than the second threshold (1 level), the installation location may be moved to perform a re-installation procedure.

Hereinafter, a method for predicting an optimal tilting direction when installing a 5G CPE according to the present invention will be described. In this regard, Figure 6b shows various LEDs provided in the 5G CPE according to the present invention. 6B, the 5G CPE includes an LED 540 indicating 5G NR signal strength. The LED 540 may be disposed on the upper side in order for the installer to easily recognize the 5G NR signal quality, but is not limited thereto and may be changed according to an application. Accordingly, the LED 540 may display the NR status as Red, Yellow, Green, or the like, respectively. For example, when the LED 540 is displayed as Green, it indicates that the 5G signal strength is in a good state and that the 5G CPE can be installed normally at the corresponding location. On the other hand, when the LED 540 is displayed in yellow, it indicates that the 5G signal strength is in a normal state, and installation is impossible unless the 5G CPE is optimally tilted in the horizontal and/or vertical directions. On the other hand, when the LED 540 is displayed as red, it indicates that the 5G signal strength is in a weak state, and installation is impossible unless the 5G CPE is moved to another location.

The 5G CPE may further include a first LED 541 for guiding the direction to the left/right according to the left and right tilt. In addition, the 5G CPE may further include a second LED 542 for guiding the direction upward and downward according to the vertical tilt.

Meanwhile, the user or installer can select the corresponding button to enter the test mode, that is, the installation mode to install the 5G CPE. In order to enter this test mode, that is, the installation mode, the button may be physically provided on an electronic device paired with a 5G CPE or a 5G CPE, or may be displayed on a display. In this regard, the 5G CPE can activate the following functions when entering the test mode, that is, the installation mode.

1) When installing 5G CPE, you can enter TX power disable, RX Only mode to protect the human body from harmful 5G NR radio waves.

2) Algorithm to find the optimum installation position and angle can be applied.

3) CPE Side BT advertise mode can be controlled to be ON so that BT pairing with electronic devices is possible as an installation aid.

On the other hand, when 5G CPE is installed, it is possible to measure 5G signals and keep the 5G CPE in a stopped state in order to find the optimal reception angle. To this end, the LED 240 indicating the 5G NR signal strength may be displayed in a Blinking state. Accordingly, by displaying the LED 240 in a different color, for example, white Blinking, it is possible to inform the user or the installer that the 5G CPE is not to be moved at the corresponding location.

Hereinafter, an installation structure and installation method of a 5G communication relay device, that is, a 5G CPE according to the present invention will be described. In this regard, FIG. 7 shows an arrangement structure of a base station and a 5G CPE according to the present invention.

Referring to FIG. 7, a 5G radio signal transmitted from a base station (BS) is difficult to be transmitted into an indoor space such as a building. Therefore, the present invention proposes a method of installing a plurality of 5G communication relay devices, that is, 5G CPEs (CPEs 1 to 3) around a space such as a window of a building. Here, CPEs 1 to 3 correspond to 5G CPEs disposed at a higher position, substantially the same position, and a lower position than the base station (BS). Accordingly, CPE 1 needs to electrically tilt the antenna beam downward in the vertical direction (Down e-tilt). On the other hand, CPE 3 needs to electrically tilt the antenna beam upward in the vertical direction. On the other hand, CPE 2 needs to form the antenna beam in the vertical direction in the Bore-site direction.

On the other hand, when Building 2 is separated by a predetermined angle in the horizontal direction compared to Building 1, e.g. 60, CPEs 1 to 3 installed in Building 2 can apply more horizontal tilt than CPEs 1 to 3 installed in Building 1. have. In this regard, the tilt in the horizontal direction applied to CPEs 1 to 3 installed in Building 2 may be determined by AoA-60 degrees. Here, AoA is the horizontal tilt angle of CPEs 1 to 3 installed in Building 1.

In this regard, differentiation points for the installation structure and installation method of a 5G communication relay device, that is, a 5G CPE according to the present invention are as follows.

1) It is necessary to match the beam direction of the antenna (operating at high frequency) with 5G linearity toward the access unit or base station (BS). To this end, there is a need for an apparatus structure capable of adjusting the angle of the antenna beam direction and sensing the angle change. Therefore, a 5G communication relay device, that is, a concept of calculating an angle from a 5G CPE to a base station (BS) is required.

2) On the other hand, in the form of an indoor unit, various installation scenarios and power connections suitable for the general home indoor environment are required in addition to the building. To this end, a scenario in which various customers can install it in a desired location is required. Therefore, it is necessary to review the indoor installation scenario of a 5G communication relay device, that is, a 5G CPE.

Looking at the rotational structure of the 5G communication relay device, that is, 5G CPE according to the present invention is as follows. In this regard, FIG. 8 shows a left and right rotation structure and a vertical rotation structure of the 5G communication relay device according to the present invention.

In this regard, FIGS. 8 (a) and (b) are related to a first combination frame corresponding to a left and right rotation structure of a 5G communication relay device according to the present invention. Specifically, FIG. 8(a) shows a perspective view in which the main body of the 5G communication relay device is combined with the first coupling frame. Meanwhile, FIG. 8(b) shows a front view of a 5G communication relay device in which the internal structure of the first combination frame is displayed. Accordingly, the main body 501 is configured to be rotatable in the left and right directions and in the up and down directions to receive 5G radio signals. To this end, the first coupling frame 550 is connected to the lower end of the body 501 and is configured to rotate the body 501 in the left and right directions.

Referring to FIG. 8B, a thread 551 is disposed inside the first coupling frame 550. In this regard, according to the rotation of the screw thread 551, the left and right rotation (tilt) angle of the 5G CPE can be known.

Meanwhile, FIGS. 8(c) and (d) are related to a second combination frame corresponding to a vertical rotation structure of a 5G communication relay device according to the present invention. Specifically, FIG. 8(c) shows a perspective view in which the main body of the 5G communication relay device is combined with the second coupling frame. Meanwhile, FIG. 8(d) shows a side view in which the main body of the 5G communication relay device is combined with the second combination frame. Accordingly, the second coupling frame 560 is connected to the side and lower ends of the body 501 and is configured to rotate the body 501 in the vertical direction. On the other hand, the lower end of the main body 501 may be configured to be fastened with a frame attached to the window. In addition, the lower end of the main body 501 may be configured to be fastened with a vertical connection part extending to a predetermined height. Detailed description of this will be described in detail below.

On the other hand, Figures 9a and 9b shows a detailed configuration for the operation of the left and right rotation structure and the vertical rotation structure of the 5G CPE according to the present invention. In this regard, the left and right rotation structure and the vertical rotation structure of the 5G CPE may be a threaded structure and a pressure sensor structure, respectively.

Specifically, FIG. 9A shows the internal structure of the first coupling frame in which threads and conductive pads are disposed. In addition, FIG. 9A shows a relative rotation angle of the first coupling frame corresponding to the position of the conductive pad.

Meanwhile, referring to FIGS. 8 and 9A, the 5G CPE further includes a driving control unit 570 for controlling the tilt of the main body in the left and right directions and in the vertical direction. When the main body 501 is rotated in the left and right direction, the driving control unit 570 obtains a rotation value in which the thread 551 inside the first coupling frame 540 rotates relative to the conductive pad 552. In this regard, the position of the pad of the conductive pad 552 in contact with the thread 551 corresponds to a relative rotation angle of the first coupling frame with respect to the body 501. Accordingly, the driving control unit 570 may calculate a tilt angle in the left and right directions according to the rotation value.

In addition, FIG. 9B shows a method of detecting an upward rotation angle according to a spring compression-based pressure sensing method according to the vertical rotation of the second coupling frame. In this regard, when the main body 501 is rotated in the vertical direction, the driving control unit 570 changes the pressure value applied to the pressure sensor 562 as the spring 561 connected to the second coupling frame 560 is compressed. . Accordingly, the driving controller 570 may calculate the tilt angle in the vertical direction according to the pressure value applied to the pressure sensor 562 while the spring 561 is compressed.

An indoor installation scenario of a 5G communication relay device according to the present invention, that is, a 5G CPE will be described below. In this regard, FIGS. 10A to 10C show an installation structure of a 5G CPE according to embodiments of the present invention.

Specifically, FIG. 10A is an installation structure (Type A) of a 5G CPE disposed on a window using a fixed pole. On the other hand, FIG. 10B is an installation structure (Type B) of a 5G CPE disposed on the side of a window using a bracket. Meanwhile, FIG. 10C is an installation structure (Type C) of a stand-type 5G CPE installed around a window.

In this regard, it is necessary to support the weight of the body 501 in the form in which the 5G CPE body 501 is suspended. To this end, it is difficult to support the weight of the 5G CPE main body 501 only by the frictional force between the fixed pole 610a and the window frame.

Meanwhile, referring to FIG. 11B, magnets 611 may be disposed in grooves at both ends of the fixing pole 610a. Accordingly, the magnet 611 may be attached to the metal 612 on both sides of the window frame by magnetic force. In this regard, support frames 613 for supporting the metal 612 may be attached to both sides of the window frame. Accordingly, an attractive force acts between the magnet 611 and the metal 612 by the magnetic force of the magnet 611. Accordingly, the force acting in the lower direction on the main body 501a in FIG. 11A can be controlled by the attractive force between the magnet 611 and the metal 612 as shown in FIG. 11B(b).

Meanwhile, FIG. 12A shows the structure of a fixed pole inserted into a fastening part attached to a lower part of a 5G CPE main body according to the present invention.

Meanwhile, the upper groove 602a and the lower groove 602b are alternately formed at different positions so that the cable can be accommodated in a predetermined space inside the fixing pole 601a. In this regard, referring to the sectional view of the fixing pole 601a of FIG. 12B, the cable may be accommodated in a space having a predetermined diameter D by the groove 602.

Accordingly, there is an advantage in that the cable can be easily accommodated in the fixed pole 601a. In addition, it is possible to solve the problem that the cable is damaged due to the movement of the cable when the 5G CPE rotates left and right and/or vertically.

In addition, FIG. 13B shows a structure in which the 5G CPE according to the present invention can rotate in the left and right directions according to the rotation of the bracket. Therefore, the present invention has the advantage that the bracket itself is rotatable, and the angle can be adjusted. Accordingly, there is an advantage that the 5G CPE can be installed at a desired angle.

13A and 13B, the bracket 610b includes a fixing part 611b and a rotating part 612b. The fixing part 611b is configured to be fixed to one side of the window frame. On the other hand, the rotating part 612b is configured to be rotatable at a predetermined angle from the fixing part 611b. Meanwhile, a driving control unit 570 for controlling the tilt of the main body 501 in the left and right directions and the vertical direction may be provided inside the 5G CPE. Accordingly, the driving control unit 570 may detect the rotation angle of the rotation unit 612b and perform a horizontal tilt of the main body 501 in consideration of the rotation angle. Here, a sensor unit may be provided to detect the rotation angle of the rotation unit 612b. Accordingly, the driving control unit 570 may determine the rotation angle of the first and second combining

frames

550 and 560 in consideration of the rotation angle. Meanwhile, when it is difficult to rotate left and right and/or vertically by more than a predetermined angle depending on the window structure, an electronic beam scan may be performed for the remaining angles.

On the other hand, in the installation structure (Type C) of the stand-type 5G CPE installed around the window as shown in FIG. 10C, the vertical extension portion and the detailed structure supporting the same will be described as follows. In this regard, FIG. 14A shows a detailed configuration of an installation structure of a stand-type 5G CPE installed around a window according to the present invention.

Meanwhile, the lower support part 610c is disposed in a space where a 5G communication relay device is installed, and is configured to support a 5G communication relay device. In addition, the vertical extension part 620c is connected to the lower support part 610c and is configured to adjust the height at which the main body 501 is disposed. Further, the horizontal connection part 630c is configured to connect the left vertical extension 621c and the right vertical extension 622c of the vertical extension 620c at a predetermined height. Here, the left vertical extension 621c and the right vertical extension 622c may be connected to the lower end of the main body 501.

The structure for preventing reverse insertion at the lower end of the main body 501 of the 5G communication relay device according to the present invention is the same as the shape of FIG. 14B(b). In addition, the structure for preventing reverse insertion at the lower end of the main body 501 of the 5G communication relay device according to the present invention can prevent reverse insertion due to repulsive force generation in case of misinsertion by N/S matching as shown in FIG. 14B(c). To this end,

magnets

511 and 512 may be provided at the lower end of the main body 501 at positions where the left vertical extension 621c and the right vertical extension 622c are fastened.

Meanwhile, FIG. 15A shows the configuration of a vertical extension part and a lower support part in the installation structure (Type C) of a stand-type 5G CPE installed around a window according to the present invention. In addition, FIG. 15B shows an extendable structure through the guard rail structure of the lower support portion.

Referring to FIG. 15A, in order to install the 5G CPE at a desired height, the vertical extension portion 620c, that is, the left vertical extension portion 621c and the right vertical extension portion 622c can be extended in length. For example, the vertical extension portion 620c, that is, the left vertical extension portion 621c and the right vertical extension portion 622c may extend from 1m to 1.5m in length.

Meanwhile, referring to FIGS. 15A and 15B, the lower support part 610c may include a first lower extension part 611c and a second lower extension part 612c. The first lower extension part 611c is formed to be accommodated in a circular side portion of the lower support part 610c. Accordingly, the first lower extension portion 611c may be configured to extend from the circular side portion to support the lower end as the length of the vertical extension portion 620c increases.

In addition, the second lower extension part 612c is formed to be accommodated in a linear side portion of the lower end support part 610c. Accordingly, the second lower extension portion 612c may be configured to extend from the linear side portion to support the lower end as the length of the vertical extension portion 620c increases. Accordingly, the first and second

lower extension portions

611c and 612c of the present invention may extend in a sliding manner through the lower support portion 610c and the guide rail structure.

Meanwhile, handles 611d and 612d are provided on the first and second

lower extension parts

611c and 612c, so that the extension lengths of the first and second

lower extension parts

611c and 612c can be adjusted. In this regard, a guide rail structure (FIG. 15B(c)) that adjusts and fixes the extension length (ie, the amount of protrusion) step by step using an internal hooking structure may be adopted.

Meanwhile, FIG. 16 shows a change in the center of gravity according to a change in the length of the vertical extension part and the configuration of the lower extension part accordingly. In this regard, the driving control unit may control the storage and extension states of the first lower extension part 611c and the second lower extension part 612c. Alternatively, the receiving and extending states of the first lower extended portion 611c and the second lower extended portion 612c may be controlled through the

handles

611d and 612d.

In this regard, the driving control unit may determine the maximum extension length that the second lower extension part 612c can extend by recognizing the wall surface of the area where the 5G communication relay device is disposed. In addition, an extension length of the second lower extension part 612c may be determined within the maximum extension length. Thereafter, the extension length of the first lower extension part 611c may be determined based on the extension length so that the 5G communication relay device does not fall and is stably disposed.

On the other hand, according to an embodiment of the present invention, if the first and second

lower extensions

611c and 612c are not extended to a sufficient length to prevent fall, the 5G radio signal may be controlled so as not to be radiated. That is, it is possible to predict that the 5G CPE will be conducted, and control the 5G radio signal not to be radiated through the transmission/reception unit (520 of FIG. 1) of the 5G CPE in advance. In this regard, if the first and second

lower extension parts

611c and 612c are not extended to a sufficient length for preventing from falling, the driving control unit may notify this to the control unit 510 of FIG. 1. Accordingly, the control unit 510 may cut off the power of the power amplifier of the transmission/reception unit 520 or the power provided to the transmission/reception unit 520 itself. Accordingly, it is possible to prevent the 5G CPE from radiating 5G radio signals in unwanted directions, thereby preventing harmful effects on the installation manager. In addition, it is possible to prevent unnecessary driving control and unnecessary power consumption by the driving control unit in a situation where the 5G CPE cannot operate normally.

Meanwhile, the driving control unit may calculate the center of gravity of the 5G communication relay device according to the length of the vertical extension part 620c. In addition, the first extension length of the first lower extension part 611c may be extended so that an angle between the center of gravity and the end point of the first extension length of the first lower extension part is equal to or greater than a predetermined angle. Thereafter, the second extension length of the second lower extension portion may be extended so that an angle formed between the center of gravity and the end point of the second extension length of the second lower extension portion is equal to or greater than a predetermined angle. Here, the predetermined angle may be set to 15 degrees, and may be changed according to the weight of the 5G CPE and the configuration of the device.

As described above, the driving control unit may calculate the center of gravity of the 5G communication relay device according to the length of the vertical extension unit 620c. In this regard, FIG. 16(a) shows the position of the center of gravity when the length of the vertical extension part is formed to have a first height (eg, 1 m).

Antennas

916 and 926. The processor implements the previously salpin functions, processes and/or methods. More specifically, in the DL (communication from the first communication device to the second communication device), higher layer packets from the core network are provided to the processor 911. The processor implements the functions of the L2 layer. In the DL, the processor provides multiplexing between logical channels and transport channels and radio resource allocation to the second communication device 920, and is responsible for signaling to the second communication device. The transmit (TX) processor 912 implements various signal processing functions for the L1 layer (ie, the physical layer). The signal processing function facilitates forward error correction (FEC) in the second communication device, and includes coding and interleaving. The coded and modulated symbols are divided into parallel streams, each stream is mapped to an OFDM subcarrier, multiplexed with a reference signal (RS) in the time and/or frequency domain, and uses Inverse Fast Fourier Transform (IFFT). These are combined together to create a physical channel carrying a time domain OFDMA symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Each spatial stream may be provided to a different antenna 916 through a separate Tx/Rx module (or transceiver 915). Each Tx/Rx module can modulate the RF carrier with each spatial stream for transmission. In the second communication device, each Tx/Rx module (or transceiver 925) receives a signal through each antenna 926 of each Tx/Rx module. Each Tx/Rx module restores information modulated with an RF carrier and provides the information to the receive (RX) processor 923. The RX processor implements a variety of layer 1 signal processing functions. The RX processor may perform spatial processing on the information to recover any spatial stream destined for the second communication device. If multiple spatial streams are directed to the second communication device, they can be combined into a single OFDMA symbol stream by multiple RX processors. The RX processor transforms the OFDMA symbol stream from time domain to frequency domain using Fast Fourier Transform (FFT). The frequency domain signal contains a separate OFDMA symbol stream for each subcarrier of the OFDM signal. The symbols and reference signal on each subcarrier are reconstructed and demodulated by determining the most probable signal constellation points transmitted by the first communication device. These soft decisions may be based on channel estimate values. The soft decisions are decoded and deinterleaved to restore the data and control signal originally transmitted by the first communication device on the physical channel. Corresponding data and control signals are provided to the processor 921.

The UL (communication from the second communication device to the first communication device) is handled in the first communication device 910 in a manner similar to that described with respect to the receiver function in the second communication device 920. Each Tx/Rx module 925 receives a signal through a respective antenna 926. Each Tx/Rx module provides an RF carrier and information to the RX processor 923. The processor 921 may be associated with a memory 924 that stores program code and data. The memory may be referred to as a computer-readable medium.
