Description

5G 통신 중계 장치5G communication relay device
본 발명은 5G 통신 중계 장치에 관한 것이다. 보다 상세하게는, 5G 기지국과 전자 기기 간에 5G 무선 신호를 전달하는 5G CPE (Customer Premises Equipment) 및 그 제어 방법에 관한 것이다.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.
전자기기(electronic devices)는 이동 가능여부에 따라 이동 단말기(mobile/portable terminal) 및 고정 단말기(stationary terminal)로 나뉠 수 있다. 다시 전자기기는 사용자의 직접 휴대 가능 여부에 따라 휴대(형) 단말기(handheld terminal) 및 거치형 단말기(vehicle mounted terminal)로 나뉠 수 있다. 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.
전자기기의 기능은 다양화되고 있다. 예를 들면, 데이터와 음성통신, 카메라를 통한 사진촬영 및 비디오 촬영, 음성녹음, 스피커 시스템을 통한 음악파일 재생 그리고 디스플레이부에 이미지나 비디오를 출력하는 기능이 있다. 일부 단말기는 전자게임 플레이 기능이 추가되거나, 멀티미디어 플레이어 기능을 수행한다. 특히 최근의 이동 단말기는 방송과 비디오나 텔레비전 프로그램과 같은 시각적 컨텐츠를 제공하는 멀티캐스트 신호를 수신할 수 있다. 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.
이와 같은 전자기기는 기능이 다양화됨에 따라 예를 들어, 사진이나 동영상의 촬영, 음악이나 동영상 파일의 재생, 게임, 방송의 수신 등의 복합적인 기능들을 갖춘 멀티미디어 기기(Multimedia player) 형태로 구현되고 있다. As such electronic devices are diversified, they are implemented in the form of a multimedia player with complex functions such as, for example, taking photos or videos, playing music or video files, and receiving games and broadcasts. have.
이러한 전자기기의 기능 지지 및 증대를 위해, 단말기의 구조적인 부분 및/또는 소프트웨어적인 부분을 개량하는 것이 고려될 수 있다.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.
상기 시도들에 더하여, 최근 전자기기는 LTE 통신 기술을 이용한 무선 통신 시스템이 상용화되어 다양한 서비스를 제공하고 있다. 또한, 향후에는 5G 통신 기술을 이용한 무선 통신 시스템이 상용화되어 다양한 서비스를 제공할 것으로 기대된다. 한편, LTE 주파수 대역 중 일부를 5G 통신 서비스를 제공하기 위하여 할당될 수 있다. 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.
이와 관련하여, 이동 단말기는 5G 통신 서비스를 다양한 주파수 대역에서 제공하도록 구성될 수 있다. 최근에는 6GHz 대역 이하의 Sub6 대역을 이용하여 5G 통신 서비스를 제공하기 위한 시도가 이루어지고 있다. 하지만, 향후에는 보다 빠른 데이터 속도를 위해 Sub6 대역 이외에 밀리미터파(mmWave) 대역을 이용하여 5G 통신 서비스를 제공할 것으로 예상된다.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.
한편, 이러한 밀리미터파(mmWave) 대역에서의 5G 통신 서비스를 위해 할당될 주파수 대역은 28GHz 대역, 39GHz 및 64 GHz 대역이 고려되고 있다. 한편, 이와 같은 28GHz 대역, 39GHz 및 64 GHz 대역에서는 파장의 길이가 짧아 해당 통신 서비스를 제공하는 셀 커버리지가 감소한다는 문제점이 있다. 이러한 문제점을 해결하기 위해, 밀리미터파(mmWave) 대역에서는 기지국과 전자 기기 간의 5G 무선 신호를 중계하는 5G 통신 중계 장치(communication relay apparatus), 즉 5G CPE (Customer Premises Equipment)를 사용하는 것을 고려할 수 있다.Meanwhile, the frequency bands to be allocated for 5G communication services in the millimeter wave (mmWave) band are the 28 GHz band, 39 GHz and 64 GHz bands. On the other hand, in the 28 GHz band, 39 GHz and 64 GHz band, the length of the wavelength is short, and thus there is a problem that the cell coverage providing the communication service is reduced. In order to solve this problem, it may be considered to use a 5G communication relay apparatus, that is, a 5G CPE (Customer Premises Equipment), which relays 5G radio signals between a base station and an electronic device in the mmWave band. .
특히, 전자 기기를 실내에서 사용하는 경우, 5G 무선 신호는 파장이 짧아서 건물 등 구조물을 통과하는 것이 어려울 수 있다. 다만, 5G 무선 신호는 건물의 유리창(window) 등 일부 구조물을 통과할 수 있다. 따라서, 5G 통신 중계 장치, 즉 5G CPE를 건물의 유리창 영역에 인접하게 배치하여야 한다. 특히, 5G 기지국으로부터 5G 무선 신호는 지향성(directivity)이 있으므로, 5G CPE를 특정 위치에서 5G 무선 신호 방향으로 특정 각도로 배치할 필요가 있다.In particular, when electronic devices are used indoors, it may be difficult to pass through structures such as buildings because the 5G radio signal has a short wavelength. However, the 5G radio signal may pass through some structures such as windows of a building. 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.
이와 같이, 5G CPE를 건물 내 실내 공간에서 최적 위치와 방향으로 사용자 또는 설치 관리자가 설치하는 경우, 5G CPE가 5G 무선 신호를 송신하면 사용자 또는 설치 관리자는 5G 무선 신호에 노출되는 문제점이 있다.In this way, when a user or an installer installs a 5G CPE in an optimal position and direction in an indoor space of a building, when the 5G CPE transmits a 5G radio signal, the user or installer is exposed to the 5G radio signal.
본 발명은 전술한 문제 및 다른 문제를 해결하는 것을 목적으로 한다. 또한, 본 발명의 다른 일 목적은 5G 통신 중계 장치의 테스트 모드에서 사용자 또는 설치 관리자가 5G 무선 신호에 노출되는 것을 방지하기 위한 것이다.It is an object of the present invention to solve the above and other problems. In addition, another object of the present invention is to prevent a user or an installer from being exposed to a 5G radio signal in a test mode of a 5G communication relay device.
또한, 본 발명의 다른 일 목적은, 5G 통신 중계 장치의 테스트 모드에서 5G 무선 신호를 송신하는 것을 제한하는 방법을 제공하기 위한 것이다.Another object of the present invention is to provide a method for limiting transmission of 5G radio signals in a test mode of a 5G communication relay device.

The 5G communication relay device includes a transceiver configured to transmit and receive a radio signal, and a control unit connected to the transceiver and configured to provide a radio signal received from a base station to an electronic device. . Meanwhile, when a cell search is initiated in a test mode, the control unit controls a radio signal not to be transmitted through the transmission/reception unit, and is exposed to the body of the user or the installer in the test mode.

The TX disable process can be performed so that it is not. Accordingly, it is possible to limit Tx transmission in the test mode after receiving the minimum control data for 5G wireless connection. Therefore, there is an advantage in that it is possible to avoid harmful effects of high frequency signals without deteriorating the 5G radio connection probability.

According to an embodiment, when it is determined that the installation of the 5G communication relay device is completed, the control unit may perform a TX activation process so that a radio signal can be transmitted through the transmission/reception unit.
일 실시 예에 따르면, 상기 제어부는 무선 자원 제어(radio resource control: RRC) 연결(connection)이 실패(fail)한 경우, RRC 재설정(re-establishment)을 위한 제어 신호는 송신될 수 있도록 제어할 수 있다. 이에 따라, 5G 무선 연결이 실패한 경우 테스트 모드에서 최소한의 제어 데이터는 송신하여 5G 무선 연결 가능성을 향상시킬 수 있다.According to an embodiment, the control unit may control a control signal for RRC re-establishment to be transmitted when a radio resource control (RRC) connection fails. have. Accordingly, when the 5G wireless connection fails, the minimum control data is transmitted in the test mode, thereby improving the possibility of 5G wireless connection.
일 실시 예에 따르면, 상기 제어부는 RRC 연결이 성공하여 RRC 연결 상태(RRC-connected state)가 된 경우, 상기 테스트 모드에 따른 테스트 과정이 완료될 때까지 무선 신호가 상기 송수신부를 통해 송신되지 않도록 제어할 수 있다.According to an embodiment, when the RRC connection is successful and the RRC-connected state is established, the control unit controls a radio signal not to be transmitted through the transceiver until the test process according to the test mode is completed. can do.
일 실시 예에 따르면, 상기 제어부는 RRC 연결 상태(RRC-connected state)에서 RRC 상태 보고(state report)를 위한 제어 데이터를 위한 제1 무선 신호는 송신되고, 사용자 데이터(user data)를 위한 제2 무선 신호는 송신되지 않도록 상기 송수신부를 제어할 수 있다. 이에 따라, 5G 무선 연결이 이루어진 경우 5G 무선 연결을 유지하기 위한 최소한의 시그널링을 송신하면서, 고주파 신호의 유해한 영향을 회피할 수 있다는 장점이 있다.According to an embodiment, the control unit transmits a first radio signal for control data for an RRC state report in an RRC-connected state, and transmits a second radio signal for user data. The transmission/reception unit may be controlled so that no radio signal is transmitted. Accordingly, when a 5G wireless connection is made, there is an advantage in that it is possible to avoid harmful effects of a high frequency signal while transmitting minimum signaling for maintaining the 5G wireless connection.
일 실시 예에 따르면, 상기 제어부는, LTE에서 new radio (NR)로 무선 인터페이스가 변경되어 NR 셀 탐색(NR cell search)이 개시된 경우, 무선 신호가 상기 송수신부를 통해 송신되지 않도록 제어할 수 있다. According to an embodiment, when a radio interface is changed from LTE to a new radio (NR) and NR cell search is started, the controller may control a radio signal not to be transmitted through the transceiver.
일 실시 예에 따르면, 상기 제어부는 5G non-stand-alone(NSA) 구조 및 5G stand-alone(SA) 구조에서 LTE에서 new radio (NR)로 무선 인터페이스가 변경되어 NR 셀 탐색(NR cell search)이 개시된 경우, 물리 하향링크 공유 채널(physical downlink shared channel: PDSCH)를 통해 시스템 정보 블록(system information block: SIB)을 수신할 수 있다. 또한, 상기 SIB가 수신된 경우, 상기 테스트 모드에 따른 테스트 과정이 완료될 때까지 무선 신호가 상기 송수신부를 통해 송신되지 않도록 제어할 수 있다.According to an embodiment, the control unit changes the radio interface from LTE to new radio (NR) in a 5G non-stand-alone (NSA) structure and a 5G stand-alone (SA) structure to search for NR cells (NR cell search). In this case, a system information block (SIB) may be received through a physical downlink shared channel (PDSCH). In addition, when the SIB is received, it is possible to control so that a radio signal is not transmitted through the transceiver until a test process according to the test mode is completed.
일 실시 예에 따르면, 상기 제어부는 5G stand-alone(SA) 구조에서 new radio (NR)로 초기 액세스(initial access)를 수행하는 경우, RRC 연결이 성공하여 RRC 연결 상태(RRC-connected state)가 되면 상기 테스트 모드에 따른 테스트 과정이 완료될 때까지 무선 신호가 상기 송수신부를 통해 송신되지 않도록 제어할 수 있다.According to an embodiment, when performing initial access to a new radio (NR) in a 5G stand-alone (SA) structure, the RRC connection is successful and the RRC-connected state is If so, it is possible to control so that a radio signal is not transmitted through the transceiver until the test process according to the test mode is completed.
일 실시 예에 따르면, 상기 제어부는 무선 신호가 상기 송수신부를 통해 송신되지 않는 TX 비활성화(Disable) 과정에서 수신 신호 품질(received signal quality)에 기반하여, TX 활성화(Enable) 절차, 틸팅(Tilting) 절차, 재설치 절차 중 하나를 수행하도록 제어할 수 있다.According to an embodiment, the control unit is based on a received signal quality in a TX disable process in which a radio signal is not transmitted through the transmission/reception unit, a TX activation procedure, a tilting procedure , You can control to perform one of the reinstallation procedures.

도 2를 참조하면, 전자 기기 또는 5G 통신 중계 장치는 제1 전력 증폭기(210), 제2 전력 증폭기(220) 및 RFIC(250)를 더 포함한다. 또한, 전자 기기는 모뎀(Modem, 400) 및 어플리케이션 프로세서(AP: Application Processor, 500)를 더 포함할 수 있다. 여기서, 모뎀(Modem, 400)과 어플리케이션 프로세서(AP, 500)와 물리적으로 하나의 chip에 구현되고, 논리적 및 기능적으로 분리된 형태로 구현될 수 있다. 하지만, 이에 한정되지 않고 응용에 따라 물리적으로 분리된 chip의 형태로 구현될 수도 있다.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 500 may be physically implemented in one chip, and may be implemented in a logically and functionally separate form. However, the present invention is not limited thereto and may be implemented in the form of physically separated chips depending on the application.
한편, 전자 기기 또는 5G 통신 중계 장치는 수신부에서 복수의 저잡음 증폭기(LNA: Low Noise Amplifier, 410 내지 440)을 포함한다. 여기서, 제1 전력 증폭기(210), 제2 전력 증폭기(220), 제어부(250) 및 복수의 저잡음 증폭기(310 내지 340)는 모두 제1 통신 시스템과 제2 통신 시스템에서 동작 가능하다. 이때, 제1 통신 시스템과 제2 통신 시스템은 각각 4G 통신 시스템과 5G 통신 시스템일 수 있다.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.
도 2에 도시된 바와 같이, RFIC(250)는 4G/5G 일체형으로 구성될 수 있지만, 이에 한정되지 않고 응용에 따라 4G/5G 분리형으로 구성될 수 있다. RFIC(250)가 4G/5G 일체형으로 구성되는 경우, 4G/5G 회로 간 동기화 (synchronization) 측면에서 유리할 뿐만 아니라, 모뎀(400)에 의한 제어 시그널링이 단순화될 수 있다는 장점이 있다. 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.
한편, RFIC(250)가 4G/5G 분리형으로 구성되는 경우, 4G RFIC 및 5G RFIC로 각각 지칭될 수 있다. 특히, 5G 대역이 밀리미터파 대역으로 구성되는 경우와 같이 5G 대역과 4G 대역의 대역 차이가 큰 경우, RFIC(250)가 4G/5G 분리형으로 구성될 수 있다. 이와 같이, RFIC(250)가 4G/5G 분리형으로 구성되는 경우, 4G 대역과 5G 대역 각각에 대하여 RF 특성을 최적화할 수 있다는 장점이 있다.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.
한편, RFIC(250)가 4G/5G 분리형으로 구성되는 경우에도 4G RFIC 및 5G RFIC가 논리적 및 기능적으로 분리되고 물리적으로는 하나의 chip에 구현되는 것도 가능하다.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.
한편, 어플리케이션 프로세서(AP, 500)는 전자 기기의 각 구성부의 동작을 제어하도록 구성한다. 구체적으로, 어플리케이션 프로세서(AP, 500)는 모뎀(400)을 통해 전자 기기의 각 구성부의 동작을 제어할 수 있다. Meanwhile, the application processor (AP) 500 is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP) 500 may control the operation of each component of the electronic device through the modem 400.
예를 들어, 전자 기기의 저전력 동작(low power operation)을 위해 전력 관리 IC (PMIC: Power Management IC)를 통해 모뎀(400)을 제어할 수 있다. 이에 따라, 모뎀(400)은 RFIC(250)를 통해 송신부 및 수신부의 전력 회로를 저전력 모드에서 동작시킬 수 있다.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.
이와 관련하여, 어플리케이션 프로세서(AP, 500)는 전자 기기가 대기 모드(idle mode)에 있다고 판단되면, 모뎀(300)을 통해 RFIC(250)를 다음과 같이 제어할 수 있다. 예를 들어, 전자 기기가 대기 모드(idle mode)에 있다면, 제1 및 제2 전력 증폭기(110, 120) 중 적어도 하나가 저전력 모드에서 동작하거나 또는 오프(off)되도록 모뎀(300)을 통해 RFIC(250)를 제어할 수 있다. In this regard, when it is determined that the electronic device is in the idle mode, the application processor AP 500 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.
다른 실시 예에 따르면, 어플리케이션 프로세서(AP, 500)는 전자 기기가 low battery mode이면, 저전력 통신이 가능한 무선 통신을 제공하도록 모뎀(300)을 제어할 수 있다. 예를 들어, 전자 기기가 4G 기지국, 5G 기지국 및 액세스 포인트 중 복수의 엔티티와 연결된 경우, 어플리케이션 프로세서(AP, 500)는 가장 저전력으로 무선 통신이 가능하도록 모뎀(400)을 제어할 수 있다. 이에 따라, 스루풋을 다소 희생하더라도 어플리케이션 프로세서(AP, 500)는 근거리 통신 모듈(113)만을 이용하여 근거리 통신을 수행하도록 모뎀(400)과 RFIC(250)를 제어할 수 있다.According to another embodiment, when the electronic device is in a low battery mode, the application processor (AP) 500 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) 500 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) 500 may control the modem 400 and the RFIC 250 to perform short-range communication using only the short-range communication module 113.
또 다른 실시 예에 따르면, 전자 기기의 배터리 잔량이 임계치 이상이면, 최적의 무선 인터페이스를 선택하도록 모뎀(400)을 제어할 수 있다. 예를 들어, 어플리케이션 프로세서(AP, 450)는 배터리 잔량과 가용 무선 자원 정보에 따라 4G 기지국 및 5G 기지국 모두를 통해 수신할 수 있도록 모뎀(400)을 제어할 수 있다. 이때, 어플리케이션 프로세서(AP, 500)는 배터리 잔량 정보는 PMIC로부터 수신하고, 가용 무선 자원 정보는 모뎀(400)으로부터 수신할 수 있다. 이에 따라, 배터리 잔량과 가용 무선 자원이 충분하면, 어플리케이션 프로세서(AP, 500)는 4G 기지국 및 5G 기지국 모두를 통해 수신할 수 있도록 모뎀(400)과 RFIC(250)를 제어할 수 있다.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. In this case, the application processor (AP, 500) may receive the remaining battery level information from the PMIC, and 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, 500) may control the modem 400 and the RFIC 250 to receive reception through both the 4G base station and the 5G base station.
한편, 도 2의 다중 송수신 시스템(multi-transceiving system)은 각각의 무선 시스템(radio System)의 송신부와 수신부를 하나의 송수신부로 통합할 수 있다. 이에 따라, RF 프론트 엔드(Front-end)에서 두 종류의 시스템 신호를 통합하는 회로부분을 제거할 수 있다는 장점이 있다. 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.
또한, 프론트 엔드 부품을 통합된 송수신부로 제어 가능하므로, 송수신 시스템이 통신 시스템 별로 분리되었을 경우보다 효율적으로 프론트 엔드 부품을 통합할 수 있다.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.
또한, 통신 시스템 별로 분리되는 경우, 필요에 따라 다른 통신 시스템을 제어하는 것이 불가능하거나, 이로 인한 시스템 지연(system delay)를 가중시키기 때문에 효율적인 자원 할당이 불가능하다. 반면에, 도 2와 같은 다중 송수신 시스템은, 필요에 따라 다른 통신 시스템을 제어하는 것이 가능하고, 이로 인한 시스템 지연을 최소화할 수 있어 효율적인 자원 할당이 가능한 장점이 있다.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.
한편, 제1 전력 증폭기(210)와 제2 전력 증폭기(220)는 제1 및 제2 통신 시스템 중 적어도 하나에서 동작할 수 있다. 이와 관련하여, 5G 통신 시스템이 4G 대역 또는 Sub6 대역에서 동작하는 경우, 제1 및 제2 전력 증폭기(220)는 제1 및 제2 통신 시스템에서 모두 동작 가능하다. 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.
반면에, 5G 통신 시스템이 밀리미터파(mmWave) 대역에서 동작하는 경우, 제1 및 제2 전력 증폭기(210, 220)는 어느 하나는 4G 대역에서 동작하고, 다른 하나는 밀리미터파 대역에서 동작할 수 있다. 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.
한편, 송수신부와 수신부를 통합하여, 송수신 겸용 안테나를 이용하여 하나의 안테나로 2개의 서로 다른 무선 통신 시스템을 구현할 수 있다. 이때, 도 2와 같이 4개의 안테나를 이용하여 4x4 MIMO 구현이 가능하다. 이때, 하향링크(DL)를 통해 4x4 DL MIMO가 수행될 수 있다. 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. In this case, 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).
한편, 5G 대역이 Sub6 대역이면, 제1 내지 제4 안테나(ANT1 내지 ANT4)는 4G 대역과 5G 대역에서 모두 동작하도록 구성될 수 있다. 반면에, 5G 대역이 밀리미터파(mmWave) 대역이면, 제1 내지 제4 안테나(ANT1 내지 ANT4)는 4G 대역과 5G 대역 중 어느 하나의 대역에서 동작하도록 구성될 수 있다. 이때, 5G 대역이 밀리미터파(mmWave) 대역이면, 별도의 복수 안테나 각각이 밀리미터파 대역에서 배열 안테나로 구성될 수 있다.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.
한편, 4개의 안테나 중 제1 전력 증폭기(210)와 제2 전력 증폭기(220)에 연결된 2개의 안테나를 이용하여 2x2 MIMO 구현이 가능하다. 이때, 상향링크(UL)를 통해 2x2 UL MIMO (2 Tx)가 수행될 수 있다. 또는, 2x2 UL MIMO에 한정되는 것은 아니고, 1 Tx 또는 4 Tx로 구현 가능하다. 이때, 5G 통신 시스템이 1 Tx로 구현되는 경우, 제1 및 제2 전력 증폭기(210, 220) 중 어느 하나만 5G 대역에서 동작하면 된다. 한편, 5G 통신 시스템이 4Tx로 구현되는 경우, 5G 대역에서 동작하는 추가적인 전력 증폭기가 더 구비될 수 있다. 또는, 하나 또는 두 개의 송신 경로 각각에서 송신 신호를 분기하고, 분기된 송신 신호를 복수의 안테나에 연결할 수 있다.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.
한편, RFIC(250)에 해당하는 RFIC 내부에 스위치 형태의 분배기(Splitter) 또는 전력 분배기(power divider)가 내장되어 있어, 별도의 부품이 외부에 배치될 필요가 없고 이로 인해 부품 실장성을 개선시킬 수 있다. 구체적으로, 제어부(250)에 해당하는 RFIC 내부에 SPDT (Single Pole Double Throw) 형태의 스위치를 사용하여 2개의 서로 다른 통신 시스템의 송신부(TX) 선택이 가능하다.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. 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.
또한, 본 발명에 따른 복수의 무선 통신 시스템에서 동작 가능한 전자 기기는 듀플렉서(duplexer, 231), 필터(232) 및 스위치(233)를 더 포함할 수 있다.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.
듀플렉서(231)는 송신 대역과 수신 대역의 신호를 상호 분리하도록 구성된다. 이때, 제1 및 제2 전력 증폭기(210, 220)를 통해 송신되는 송신 대역의 신호는 듀플렉서(231)의 제1 출력 포트를 통해 안테나(ANT1, ANT4)에 인가된다. 반면에, 안테나(ANT1, ANT4)를 통해 수신되는 수신 대역의 신호는 듀플렉서(231)의 제2 출력포트를 통해 저잡음 증폭기(310, 340)로 수신된다. 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.
필터(232)는 송신 대역 또는 수신 대역의 신호를 통과(pass)시키고 나머지 대역의 신호는 차단(block)하도록 구성될 수 있다. 이때, 필터(232)는 듀플렉서(231)의 제1 출력 포트에 연결되는 송신 필터와 듀플렉서(231)의 제2 출력포트에 연결되는 수신 필터로 구성될 수 있다. 대안적으로, 필터(232)는 제어 신호에 따라 송신 대역의 신호만을 통과시키거나 또는 수신 대역의 신호만을 통과시키도록 구성될 수 있다.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.
스위치(233)는 송신 신호 또는 수신 신호 중 어느 하나만을 전달하도록 구성된다. 본 발명의 일 실시 예에서, 스위치(233)는 시분할 다중화(TDD: Time Division Duplex) 방식으로 송신 신호와 수신 신호를 분리하도록 SPDT (Single Pole Double Throw) 형태로 구성될 수 있다. 이때, 송신 신호와 수신 신호는 동일 주파수 대역의 신호이고, 이에 따라 듀플렉서(231)는 서큘레이터(circulator) 형태로 구현될 수 있다.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.
한편, 본 발명의 다른 실시 예에서, 스위치(233)는 주파수 분할 다중화(FDD: Time Division Duplex) 방식에서도 적용 가능하다. 이때, 스위치(233)는 송신 신호와 수신 신호를 각각 연결 또는 차단할 수 있도록 DPDT (Double Pole Double Throw) 형태로 구성될 수 있다. 한편, 듀플렉서(231)에 의해 송신 신호와 수신 신호의 분리가 가능하므로, 스위치(233)가 반드시 필요한 것은 아니다. 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.
한편, 본 발명에 따른 전자 기기는 제어부에 해당하는 모뎀(400)을 더 포함할 수 있다. 이때, RFIC(250)와 모뎀(400)을 각각 제1 제어부 (또는 제1 프로세서)와 제2 제어부(제2 프로세서)로 지칭할 수 있다. 한편, RFIC(250)와 모뎀(400)은 물리적으로 분리된 회로로 구현될 수 있다. 또는, RFIC(250)와 모뎀(400)은 물리적으로 하나의 회로에 논리적 또는 기능적으로 구분될 수 있다.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.
모뎀(400)은 RFIC(250)를 통해 서로 다른 통신 시스템을 통한 신호의 송신과 수신에 대한 제어 및 신호 처리를 수행할 수 있다. 모뎀(400)은 4G 기지국 및/또는 5G 기지국으로부터 수신된 제어 정보(Control Information)을 통해 획득할 수 있다. 여기서, 제어 정보는 물리 하향링크 제어 채널(PDCCH: Physical Downlink Control Channel)을 통해 수신될 수 있지만, 이에 한정되는 것은 아니다. 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.
모뎀(400)은 특정 시간 및 주파수 자원에서 제1 통신 시스템 및/또는 제2 통신 시스템을 통해 신호를 송신 및/또는 수신하도록 RFIC(250)를 제어할 수 있다. 이에 따라, RFIC(250)는 특정 시간 구간에서 4G 신호 또는 5G 신호를 송신하도록 제1 및 제2 전력 증폭기(210, 220)를 포함한 송신 회로들을 제어할 수 있다. 또한, RFIC(250)는 특정 시간 구간에서 4G 신호 또는 5G 신호를 수신하도록 제1 내지 제4 저잡음 증폭기(310 내지 340)를 포함한 수신 회로들을 제어할 수 있다.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.
한편, 도 2와 같은 다중 송수신 시스템이 구비된 전자 기기로 5G 무선 신호를 전달하는 5G 통신 중계 장치, 즉 5G CPE (Customer Premises Equipment) 및 그 제어 방법에 대해 살펴보기로 한다.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.
이와 관련하여, 기존 브로드 밴드 망(broadband network)의 속도가 낮고, 새로운 기가 네트워크를 설치하기 위해서는 막대한 비용이 발생하기 때문에, 5G CPE가 필요하다. 또한, 새로운 가입자가 생기더라도 각 세대별 거리가 멀기 때문에 케이블을 매설하고, 엔지니어들이 방문해서 설치하는데 많은 비용이 발생할 수 있다. 이러한 문제점을 해결하기 위해 5G 통신 서비스는 실내에서 5G CPE를 통해 제공되는 것이 바람직하다.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.
4G LTE 이후 새로운 비즈니스를 창출하고자 하는 망 사업자들이 경쟁적으로 5G 망 구축을 진행하고 있다. 하지만, 5G 망이 4G 망보다 빠르다는 장점만으로 새로운 비즈니스를 창출하기는 어려운 상황이다. 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.
따라서, 사업자(operator)들은 기존의 케이블로 인터넷 서비스를 제공하는 대신, 초고속 통신망을 활용하여 무선으로 각 가정으로 인터넷을 공급하는 방안을 고려할 수 있다.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.
하지만, 기존 LTE나 3G에서 사용한 주파수와 비교하면, 5G는 초고속 통신망으로 매우 높은 주파수 대역을 사용한다. 따라서, 5G 무선 신호는 건물, 나무 등 주변의 오브젝트에 기인하여 RF 손실이 크게 발생한다.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 significant RF loss due to surrounding objects such as buildings and trees.
사업자는 5G CPE를 제공하고, 사용자가 self-install을 하여 엔지니어가 방문하거나 케이블을 따로 매설하지 않기를 원할 수 있다. 하지만, 5G NR radio 특성상 설치를 위한 5G CPE의 최적 설치 각도 및 위치를 파악하기 힘들다는 문제점이 있다.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.
따라서, 본 발명에 따른 5G 통신 중계 장치, 즉 5G CPE는 전술한 문제점을 해결하기 위해 다음과 같은 기술적 특징이 구현될 수 있다.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) 높은 전력 등급, 즉 Power class 1(예: 48dBm)을 지원하는 안테나를 사용하여 indoor용 CPE를 제안한다.1) We propose an indoor CPE using an antenna that supports high power class, that is, Power class 1 (eg, 48dBm).
2) 지향성 안테나와 빔포밍 방식 사용하여 5G CPE의 5G 서비스 coverage를 확장한다.2) Extend 5G service coverage of 5G CPE using a directional antenna and beamforming method.
3) 지향성 안테나를 사용하는 경우 5G 서비스를 제공하는 각도 영역(angular region)이 제한되는 이슈를 커버하기 위한 방안을 적용한다3) When using a directional antenna, apply a method to cover the issue of limited angular regions providing 5G services.
4) 높은 주파수를 사용하는 경우 인체에 해로운 영향이 발생하지 않도록 safety 방안을 적용한다.4) When using a high frequency, apply safety measures to prevent harmful effects on the human body.
이러한 본 발명에 따른 5G 통신 중계 장치, 즉 5G CPE의 기술적 특징을 구현하기 위한 구체적인 방식은 다음과 같다.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) 고주파 특성을 갖는 5G 무선 신호는 직진성이 강하므로, 실내에서 신호가 포착(capture)되는 영역을 탐색하기 어렵다. 따라서, 실내에서 신호를 수신 및 포착하기 위해 5G CPE에 대한 적절한 포지셔닝(positioning)이 필요하다.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) 고주파 특성에 따라 파장이 짧아 신호의 도달 거리가 짧기 때문에, 기지국 방향, 즉 최적 신호 방향으로 빔포밍을 수행하여야 5G 수신 성능을 만족할 수 있다. 따라서, 5G CPE와 기지국 간 최적 신호 방향을 탐색하는 틸팅(tilting) 동작이 필요하다.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, 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.
이와 관련하여, 도 3은 본 발명에 따른 5G 통신 중계 장치, 즉 5G CPE의 설치 방법에 대한 개념도이다. 한편, 도 4a 및 도 4b는 본 발명에 따른 5G 통신 중계 장치, 즉 5G CPE에서 수행되는 제어 동작의 흐름도를 나타낸다. 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.
도 3의 (a)를 참조하면, 5G NR(New Radio) 신호 강도(signal strength)를 측정할 수 있다. 이와 관련하여 도 4a를 참조하면, 5G NR 측정을 수행하는 동안 테스트 모드가 수행(S110)될 수 있다. 한편, 테스트 모드가 수행(S110)됨에 따라, TX 비활성화(Disable) 절차가 수행(S120)될 수 있다. 이와 관련하여, 테스트 모드가 수행(S110)되고, TX 비활성화(Disable) 절차가 수행(S120)되는 동안 5G NR 기지국과는 아직 연결 상태가 아니다. 따라서, 도 4a에 도시된 바와 같이, Test Tool에 해당하는 전자 기기를 통해 'No NR Connection'임을 표시할 수 있다. 여기서, No NR Connection은 무선 자원 제어(radio resource control: RRC) 연결(connection) 상태가 아님을 의미한다.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.
한편, 이러한 테스트 모드는 주로 5G CPE의 초기 설치 시에 이루어진다. 하지만, 이에 한정되는 것은 아니고, 전파 환경 변화에 따라 사용자에게 이를 통지하고 사용자가 테스트 모드를 선택하는 경우에 수행될 수 있다. TX 비활성화(Disable) 절차가 수행(S120)되는 동안 5G CPE는 기지국 또는 주변 전자 기기로의 임의의 신호 송신 절차를 수행하지 않는다. 하지만, 5G NR 신호 측정에 따른 NR 측정 보고를 위해 제어 신호 송신은 예외적으로 수행될 수 있다. 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.
5G NR 신호 강도가 일정 수준 이상이 되지 않으면, 도 3(b)와 같이 실내의 다른 위치로 5G CPE를 이동시킬 수 있다. 이와 같이 실내의 다른 위치에서 5G NR 신호 강도가 일정 수준 이상이 되면, NR 연결(connection)이 수행된다. 이와 관련하여 도 4a를 참조하면, TX 비활성화(Disable) 절차가 수행(S120)되는 동안에도 5G NR 신호 측정에 따른 NR 측정이 수행(S130)될 수 있다. 이와 관련하여, NR 측정이 수행(S130)됨에 따라 NR 연결(connection)이 이루어질 수 있다. 따라서, 도 4a에 도시된 바와 같이, Test Tool에 해당하는 전자 기기를 통해 'NR Connection'임을 표시할 수 있다. 여기서, NR Connection은 무선 자원 제어(radio resource control: RRC) 연결(connection) 상태임을 의미한다.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.
NR 연결이 이루어지면, 도 3(c)와 같이 틸팅(tilting) 동작을 통해 적절한 고도(altitude) 검출을 수행할 수 있다. 이러한 틸팅 동작은 기계적 틸팅 동작 이외에 미세한 각도 또는 높이 조정을 위해 빔 포밍 등을 통해 전기적 틸팅 동작도 가능하다.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.
도 3(c)를 참조하면, 수평 방향(horizontal direction)에서 5G CPE를 일정 각도만큼 회전(S141)시킬 수 있다. 예를 들어, 수평 방향에서 ±30도의 방위각(azimuth angle) 범위 내에서 5G CPE를 회전시킬 수 있다. 하지만, 방위각 회전 각도는 이에 한정되는 것은 아니고 응용에 따라 임의의 회전 각도일 수 있다. 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.
또한, 도 3(c)를 참조하면, 수직 방향(vertical direction)에서 5G CPE를 일정 각도만큼 회전(S142)시킬 수 있다. 예를 들어, 수직 방향에서 ±30도의 고도각(elevation angle) 범위 내에서 5G CPE를 회전시킬 수 있다. 하지만, 고도각 회전 각도는 이에 한정되는 것은 아니고 응용에 따라 임의의 회전 각도일 수 있고, 방위각 회전 각도와 상이한 값일 수 있다. 또한, 수직 방향에서 5G CPE를 일정 각도만큼 회전시키는 것에 대신하여 5G CPE가 설치된 설치 기구의 높이를 조절할 수 있다. 따라서, 5G CPE를 수평 방향 및 수직 방향에서 최적의 신호 수신 방향으로 배치시킬 수 있다. 이에 따라, 5G CPE는 테스트 모드를 오프하고 기지국으로부터 수신된 신호를 전자 기기로 전달하고, 전자 기기로부터 수신된 신호를 기지국으로 전달할 수 있다.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.
따라서, 본 발명에 따른 5G CPE 제어 동작은 다음과 같이 2 단계로 이루어질 수 있다.Therefore, the 5G CPE control operation according to the present invention can be performed in two steps as follows.
1단계: 설치 시 사용자 또는 설치 관리자의 안전을 보장하기 위한 Tx disable 알고리즘 적용Step 1: Apply the Tx disable algorithm to ensure the safety of users or installers during installation
2단계: 설치 시 어느 방향이 최적의 Tilt 방향인지 빠르게 감지하는 알고리즘 적용Step 2: Apply an algorithm that quickly detects which direction is the optimal tilt direction during installation
이와 관련하여, Tx disable 알고리즘 적용은 테스트 모드가 수행(S110)되고, TX 비활성화(Disable) 절차가 수행(S120)되는 동안 이루어진다. 한편, NR connection이 이루어진 경우에도 Tx disable 알고리즘은 테스트 모드가 종료되기 전까지 이루어질 수 있다. 한편, 설치 시 어느 방향이 최적의 Tilt 방향인지 빠르게 감지하는 알고리즘 적용은 수평 회전 단계(S141) 및 수직 회전 단계(S142)를 통해 이루어진다.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. 5A 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. In addition, FIG. 5B shows a detailed configuration of a 5G CPE and an electronic device according to the present invention.
도 5a를 참조하면, Test Tool은 5G CPE를 통해 기지국과 5G 통신을 수행하는 전자 기기이다. 한편, BT는 5G CPE와 전자 기기 간의 근거리 통신을 수행하기 위한 무선 인터페이스로, 예를 들어 블루투스일 수 있다. 하지만, 블루투스에 한정되는 것은 아니고 와이파이, 지그비 등 임의의 근거리 통신 무선 인터페이스일 수 있다. 한편, RF/Protocol은 5G CPE의 송수신부에 해당하고, 5G CPE의 제어부 (프로세서)에 의해 제어 동작이 수행될 수 있다. 또한, LED는 5G CPE에 구비되고, 5G CPE의 설치 상태 및 5G 신호 품질 등을 표시할 수 있다.5A, 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.
도 5b를 참조하면, 5G CPE(500)는 제어부 (프로세서)(510), 송수신부(transceiver, 520), 제2 송수신부(530) 및 표시부(540)를 포함한다. 한편, 전자 기기(100)는 무선 통신부에 해당하는 송수신부(110), 출력부(150) 및 제어부(180)를 포함한다. Referring to FIG. 5B, 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.
또한, 본 발명에 따른 5G 통신 시스템은 4G 기지국(600) 및 5G 기지국(700)을 포함하도록 구성 가능하다. 이와 관련하여, 5G CPE(500)는 5G 기지국(700)으로부터 5G 무선 신호를 수신하여 전자 기기(100)로 중계할 수 있다. 또한, 5G CPE(500)는 전자 기기(100)로부터 5G 무선 신호를 수신하여 5G 기지국(700)으로 전달할 수 있다. 이와 관련하여, 5G NSA (non-stand-alone) 구조에서, 5G CPE(500)는 4G 기지국(600) 및 5G 기지국(700)과 이중 연결 상태(EN-DC)를 유지할 수 있다. 또한, 5G NSA 구조에서, 5G CPE(500)는 일부 제어 정보를 4G 기지국(600) 및 5G 기지국(700)으로 모두 전달할 수 있다.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.

도 3 내지 도 5b를 참조하면, 본 발명에 따른 5G CPE 제어 동작은 다음과 같이 2 단계로 이루어질 수 있다.3 to 5B, the 5G CPE control operation according to the present invention may be performed in two steps as follows.

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.
도 5b를 참조하면, Test Tool은 전자 기기(100)에 해당한다. 한편, RF/Protocol은 5G CPE의 송수신부 또는 제어부에 해당할 수 있다. 설명의 편의를 위해, RF/Protocol은 5G CPE의 제어부(510)에 해당하는 것으로 지칭한다. 한편, BT는 전자 기기(100)와 근거리 통신을 수행하기 위한 제2 무선 인터페이스를 제공하는 5G CPE의 제2 송수신부(530)로 지칭한다. 또한, LED는 5G CPE의 설치 상태 및 5G 신호 품질 등을 표시 표시부(540)로 지칭한다. Referring to FIG. 5B, the test tool corresponds to the 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.
5G CPE의 제어부(510)는 통신 기능 활성화(activation)를 통해 LTE 기지국과 LTE 연결(LTE connection) 상태가 되도록 제어할 수 있다. LTE 연결 상태에서 NR 기지국으로부터 수신되는 수신 신호에 대한 NR 측정 (NR measurement)을 수행할 수 있다. 이와 관련하여, NR 측정은 5G NR Disable 과정(S120) 동안에도 수행될 수 있다. 또한, NR 측정은 최적 Tilt 제어 과정(S140) 동안에도 수행될 수 있다.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).
한편, 5G CPE의 제어부(510)는 5G CPE를 설치(install)하려는 사용자 입력이 수신(예: Button On)되면, 테스트 모드를 수행(S110) 할 수 있다. 또한, 제어부(510)는 테스트 모드에 진입 (즉, 테스트 모드라고 판단)한 경우 제2 송수신부(530)를 통해 전자 기기(100)와 페어링 되도록 제어할 수 있다. 테스트 모드에서 전자 기기(100)와 페어링을 위해, 주변 전자 기기와의 Advertising 과정을 통해 주변 전자 기기를 인식할 수 있다.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.
5G NR Disable 과정(S120)과 관련하여, 제어부(510)는 5G 기지국으로부터 특정 제어 신호가 수신되거나 또는 RRC 연결 상태인 경우, 무선 신호가 송수신부(520)를 통해 송신되지 않도록 TX 비활성화(Disable) 과정(process)을 수행한다. 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.
최적 Tilt 제어 과정(S140)과 관련하여, 제어부(510)는 수평 방향 및/또는 수직 방향에서 5G 기지국으로부터 수신되는 신호의 최적 방향을 탐색할 수 있다. 이에 따라, 제어부(510)는 5G 기지국으로부터의 수신 신호 품질(received signal quality)에 기반하여, TX 활성화(Enable) 절차(S150), 틸팅(Tilting) 절차, 재설치 절차 중 하나를 수행할 수 있다. 따라서, 수신 신호 품질이 양호한 경우, 제어부(510)는 5G CPE가 해당 위치에서 설치 가능함을 표시부(540)를 통해 표시할 수 있다. 즉, 제어부(510)는 5G CPE가 해당 위치에서 설치 가능한지 여부와 관련된 정보 또는 NR 상태(status)를 표시부(540)로 전달할 수 있다. 이에 따라, 표시부(540)는 NR 상태(status)를 각각 Red, Yellow, Green 등으로 표시할 수 있다. 예를 들어, LED가 Green으로 표시되면 5G 신호 강도가 양호한 상태(good state)이고, 5G CPE가 해당 위치에서 정상 설치 가능함을 나타내다. 반면에, LED가 Yellow로 표시되면 5G 신호 강도가 일반 상태(normal state)이고, 5G CPE를 수평 및/수직 방향에서 최적 틸트 하지 않으면 설치가 불가능함을 나타낸다. 반면에, LED가 Red로 표시되면 5G 신호 강도가 취약 상태(weak state)로, 5G CPE를 다른 위치로 이동하지 않으면 설치가 불가능함을 나타낸다.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.
TX 활성화(Enable) 절차(S150)가 수행되면, 제어부(510)는 5G 네트워크로의 ping 동작을 통해 5G 네트워크에 액세스하고, 테스트 모드를 종료한다. 이와 관련하여, 제어부(510)는 PDN (Packet Data Network) 어태치(attach)가 완료된 경우, 테스트 모드를 종료하고 사용자 데이터를 송신할 수 있다. 이에 따라, 5G CPE는 5G 기지국 및 5G 네트워크에 모두 연결 상태가 된다.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.
전술한 바와 같이, 테스트 모드가 수행(S110)되면, 제2 송수신부(530)는 전자 기기(100)와 페어링 동작 수행할 수 있다. 전자 기기(100)와 페어링이 이루어지면, 제2 송수신부(530)는 수신 신호 품질, 예를 들어 RSRP(Reference Signal Received Power)를 전자 기기(100)로 전달할 수 있다. 한편, 테스트 모드가 종료되면, 전자 기기(100)와 5G CPE와의 정보 전달이 종료될 수 있다.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.
한편, 도 6은 본 발명에 따른 5G CPE의 포지셔닝 및 틸팅 제어 방법의 흐름도를 나타낸다. 도 5a 및 도 6을 참조하면, 5G CPE의 포지셔닝 및 틸팅 제어 방법은 제어부(510)가 송수신부를 통해 5G 기지국으로부터 수신된 신호를 기반으로 수행될 수 있다. 이와 관련하여, 5G CPE의 포지셔닝 및 틸팅 제어 방법은 기계적 방식 또는 전기적 방식으로 수행될 수 있다.Meanwhile, FIG. 6 shows a flowchart of a method for controlling positioning and tilting of a 5G CPE according to the present invention. 5A and 6, the positioning and tilting control method of the 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.
도 6을 참조하면, 제어부(510)는 해당 위치에서 5G NR 측정(S130)을 수행할 수 있다. 5G NR 측정(S130)에 따라 5G 네트워크에 어태치(attach)가 가능하지 않다고 판단되면 LED를 Red로 표시할 수 있다. 이러한 RRC 연결 실패와 같은 상황이 영구적이라고 판단되면, 해당 위치가 아닌 다른 위치로 5G CPE를 포지셔닝 하도록 포지션 제어(S101)를 수행할 수 있다. 이와 관련하여, 5G CPE가 이동 가능 범위 내에서 자율적으로 포지션 제어(S101)를 수행할 수 있다. 대안으로, 5G CPE는 LED 등 표시부를 통해 또는 사용자 단말 등 주변 전자 기기를 통해 포지션 제어(S101)가 필요함을 표시할 수 있다.Referring to FIG. 6, 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.
한편, 5G NR 측정(S130)을 통한 수신 신호 품질, 예를 들어 RSRP에 따라 수평 방향 회전 (틸트) 제어(S140) 및/또는 수직 방향 회전 (틸트) 제어(S150) 동작을 수행할 수 있다. 이와 관련하여, 수평 방향 회전 (틸트) 제어(S140) 및/또는 수직 방향 회전 (틸트) 제어(S150) 동작은 각각 좌우 회전 (틸트) 및/또는 상하 회전 (틸트)에 해당할 수 있다.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.
이와 관련하여, 5G NR 측정(S130)을 통한 수신 신호 품질인 임계치 이하이면, 수평 방향 회전 (틸트) 제어(S141)를 수행할 수 있다. 수평 방향 회전 (틸트) 제어(S141)를 통해서도 통한 수신 신호 품질인 임계치 이하이면, 수직 방향 회전 (틸트) 제어(S142) 동작을 수행할 수 있다. 이와 관련하여, 수신 신호 품질인 임계치는 3 level에 해당할 수 있다. 여기서, 3 level은 LED가 Green으로 표시되는 5G 신호 강도가 양호한 상태(good state)이고, 5G CPE가 해당 위치에서 정상 설치 가능함을 나타내다. 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.
이와 관련하여, 5G CPE 내의 배열 안테나의 수평 방향의 안테나 개수가 수직 방향의 안테나 개수보다 더 많도록 설정될 수 있다. 따라서, 수평 방향으로 안테나 빔을 정밀하게 조정하고, 수직 방향으로 안테나 빔을 다시 조정할 수 있다. 이와 관련하여, 수평 방향 회전 (틸트) 제어(S140)를 통해서 수신 신호 품질이 임계치 이상이면 더 이상 수직 방향 회전 (틸트) 제어(S150) 동작을 수행할 필요가 없다는 장점이 있다. 따라서, 5G CPE의 수직 방향 회전 (틸트)를 가능한 수행하지 않아 5G CPE의 기구적 안정성을 향상시킬 수 있다는 장점이 있다. 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.
따라서, 해당 위치 및 각도에서 수신 신호 품질이 임계치 이상이면 강 전계(strong electric field) 상태로 판단하고 틸트 등 조정 절차를 중단(stop adjustment)할 수 있다. 또한, 수평 방향 회전 (틸트) 제어(S141)를 통해 수신 신호 품질이 임계치 이상이면 강 전계(strong electric field) 상태로 판단하고 틸트 등 조정 절차를 중단(stop adjustment)할 수 있다. 또한 수직 방향 회전 (틸트) 제어(S142)를 통해 수신 신호 품질이 임계치 이상이면 강 전계(strong electric field) 상태로 판단하고 틸트 등 조정 절차를 중단(stop adjustment)할 수 있다.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.
반면에, 수직 방향 회전 (틸트) 제어(S142)를 통해서도 수신 신호 품질이 임계치 미만이면 약 전계(weak electric field) 상태로 판단할 수 있다. 이에 따라, LED를 Yellow로 표시하여 5G 신호 강도가 일반 상태(normal state)이고, 5G CPE를 수평 및/수직 방향에서 최적 틸트 하지 않으면 설치가 불가능함을 표시할 수 있다. 한편, 5G 신호 강도에 따라, LED를 Red로 표시하여 5G 신호 강도가 취약 상태(weak state)로, 5G CPE를 다른 위치로 이동하지 않으면 설치가 불가능함을 표시할 수 있다. 구체적으로, 수신 신호 품질이 상기 제1 임계치 미만이고 제2 임계치 이상 (2 level)이면, 틸팅 절차를 수행하도록 제어할 수 있다. 반면에, 수신 신호 품질이 상기 제2 임계치 미만 (1 level)이면, 설치 장소를 이동하여 재설치 절차를 수행하도록 제어할 수 있다.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.
이하에서는, 본 발명에 따른 5G CPE 설치 시 최적 틸팅 방향 예측 방법에 대해 살펴보기로 한다. 이와 관련하여, 도 7은 본 발명에 따른 5G CPE에 구비되는 다양한 LED를 나타낸다. 도 7를 참조하면, 5G CPE는 5G NR 신호 강도를 나타내는 LED(540)를 포함한다. LED(540)는 설치 관리자가 5G NR 신호 품질을 용이하게 인식하기 위해 상부 측면에 배치될 수 있지만, 이에 한정되는 것은 아니고 응용에 따라 변경 가능하다. 이에 따라, LED(540)는 NR 상태(status)를 각각 Red, Yellow, Green 등으로 표시할 수 있다. 예를 들어, LED(540)가 Green으로 표시되면 5G 신호 강도가 양호한 상태(good state)이고, 5G CPE가 해당 위치에서 정상 설치 가능함을 나타내다. 반면에, LED(540)가 Yellow로 표시되면 5G 신호 강도가 일반 상태(normal state)이고, 5G CPE를 수평 및/수직 방향에서 최적 틸트 하지 않으면 설치가 불가능함을 나타낸다. 반면에, LED(540)가 Red로 표시되면 5G 신호 강도가 취약 상태(weak state)로, 5G CPE를 다른 위치로 이동하지 않으면 설치가 불가능함을 나타낸다.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 7 shows a variety of LEDs provided in the 5G CPE according to the present invention. Referring to FIG. 7, 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.
5G CPE는 좌우 틸트에 따라 좌측/우측으로 방향을 가이드하는 제1 LED(541)를 더 포함할 수 있다. 또한, 5G CPE는 상하 틸트에 따라 상부/하부로 방향을 가이드하는 제2 LED(542)를 더 포함할 수 있다. 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.
한편, 사용자 또는 설치 관리자가 5G CPE를 설치하기 위해 테스트 모드, 즉 설치 모드로 진입하기 위해 해당 버튼을 선택할 수 있다. 이러한 테스트 모드, 즉 설치 모드로 진입하기 위해 해당 버튼은 5G CPE 또는 5G CPE와 페어링된 전자 기기에 물리적으로 구비되거나 또는 디스플레이 상에 표시될 수 있다. 이와 관련하여, 5G CPE는 테스트 모드, 즉 설치 모드 진입 시 다음과 같은 기능을 활성화할 수 있다.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) 5G CPE 설치 시 5G NR 유해 전파로부터 인체를 보호하기 위하여 TX power disable, RX Only mode로 진입할 수 있다.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) 최적 설치 위치, 각도를 찾기 위한 알고리즘을 적용할 수 있다.2) Algorithm to find the optimum installation position and angle can be applied.
3) 설치 보조수단으로 전자 기기와 BT pairing 이 가능하게 CPE Side BT advertise mode가 ON 상태가 되도록 제어할 수 있다.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.
한편, 5G CPE 설치 시, 5G 신호를 측정하고, 최적의 수신 각도를 찾기 위하여 5G CPE를 정지 상태로 유지하도록 할 수 있다. 이를 위해, 5G NR 신호 강도를 표시하는 LED(240)를 Blinking 상태로 표시할 수 있다. 이에 따라, LED(240)를 다른 색, 예컨대 흰색 Blinking으로 표시하여, 사용자 또는 설치 관리자에게 해당 위치에서 5G CPE를 이동시키지 않을 것을 알려줄 수 있다.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.
이하에서는, 본 발명에 따른 셀 선택 및 NR 측정 시나리오에 대해 설명하기로 한다. 이와 관련하여, 도 8a는 본 발명에 따른 5G CPE에서의 셀 선택 및 NR 측정 방법의 흐름도를 나타낸다. 한편, 도 8b는 본 발명의 일 실시 예에 따른 5G CPE에서의 송신 제어 동작의 흐름도를 나타낸다.Hereinafter, a cell selection and NR measurement scenario according to the present invention will be described. In this regard, FIG. 8A shows a flowchart of a cell selection and NR measurement method in 5G CPE according to the present invention. Meanwhile, FIG. 8B is a flowchart of a transmission control operation in 5G CPE according to an embodiment of the present invention.
도 8a를 참조하면, 5G CPE에서의 셀 선택 및 NR 측정 방법은 Power On 단계(S310), 주파수 스캐닝 단계(S321), PSS/SSS 동기화 단계(S322), MIB 수신 단계(S323) 및 SIB 수신 단계(S324)를 포함한다. 전술한 단계의 기술적 특징은 다음과 같다.Referring to FIG. 8A, the cell selection and NR measurement method in 5G CPE includes a Power On step (S310), a frequency scanning step (S321), a PSS/SSS synchronization step (S322), an MIB receiving step (S323), and a SIB receiving step. It includes (S324). The technical characteristics of the above steps are as follows.
1) Power On 단계(S310)1) Power On step (S310)
5G CPE는 이미 액세스된 cell이 있는 경우 저장되어 있는 cell information을 사용하고, 액세스된 cell이 없는 경우 cell search를 진행한다.5G CPE uses the stored cell information when there is an already accessed cell, and proceeds with a cell search when there is no accessed cell.
2) Cell search - Frequency scanning 단계(S321)2) Cell search-Frequency scanning step (S321)
5G CPE가 기지국이 속한 셀과의 시간 및 주파수 동기화를 획득하고 셀의 물리 계층 셀 ID를 검출하는 절차이다. 따라서, cell search을 통해 5G CPE는 기지국과 통신을 시작한다. This is a procedure in which the 5G CPE acquires time and frequency synchronization with the cell to which the base station belongs and detects the physical layer cell ID of the cell. Therefore, the 5G CPE starts communicating with the base station through cell search.
3) PSS/SSS synchronization 단계(S322)3) PSS/SSS synchronization step (S322)
5G CPE는 PSS(Primary synchronization signal)과 SSS(secondary synchronization signal)을 통해 PSS/SSS synchronization를 수행하여, cell selection이 가능하다.The 5G CPE performs PSS/SSS synchronization through a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), enabling cell selection.
4) MIB 수신 단계 (S323) 및 SIB 수신 단계 (S324)4) MIB receiving step (S323) and SIB receiving step (S324)
기지국은 동기신호(예. PSS, SSS)와 셀 공통신호(예. CRS)를 주기적으로 전송하고, PBCH도 주기적으로 전송한다.The base station periodically transmits synchronization signals (eg PSS, SSS) and cell common signals (eg CRS), and also periodically transmits PBCH.
5G CPE는 PSS, SSS, CRS, PBCH를 수신하여 동기를 획득하고, PBCH에 포함된 MIB(Master information block)을 복호하고, 이를 PDSCH 탐색과 SIB 수신하기 위해 사용한다.The 5G CPE acquires synchronization by receiving PSS, SSS, CRS, and PBCH, and decodes the MIB (Master information block) included in the PBCH, and uses it for PDSCH discovery and SIB reception.
MIB는 PBCH를 통해 전송되고, 망 접속에 필요한 기본 정보, Broadcast downlink 대역폭 정보 및 SFN(System frame number)를 포함한다MIB is transmitted through PBCH and includes basic information required for network access, broadcast downlink bandwidth information, and SFN (System frame number).
SIB는 PDSCH를 통해 전송되고, SIB message는 종류에 따라 전송 주기가 다르다. 한편, 전송 주기가 같은 SIB message를 하나의 SI(system information) 메시지로 결합하여 전송될 수 있다.The SIB is transmitted through the PDSCH, and the transmission period of the SIB message is different according to the type. Meanwhile, an SIB message having the same transmission period may be combined and transmitted as a single system information (SI) message.
도 8b를 참조하면, 본 발명에 따른 5G CPE의 5G NR 신호 송신 제어 방법의 주요 특징을 나타낸다. Referring to FIG. 8B, it shows the main features of the 5G NR signal transmission control method of the 5G CPE according to the present invention.
이와 관련하여, 5G NR에서 사용하는 6GHz 이상의 5G NR 신호는 기존 통신 신호 대비 FCC 규격이 엄격하다. 따라서, 5G NR에서 사용하는 6GHz 이상의 고 주파수 대역의 Tx power가 인체에 유해한 영향을 미칠 수 있다. 이러한 문제점을 해결하기 위해, 본발명에서는 다음과 같은 2가지 Tx disable 방법을 제안한다.In this regard, 5G NR signals of 6 GHz or higher used in 5G NR have strict FCC standards compared to conventional communication signals. Therefore, the Tx power of a high frequency band of 6 GHz or higher used in 5G NR may have a harmful effect on the human body. To solve this problem, the present invention proposes the following two Tx disable methods.
방법1 Method 1 . Cell selection 이전에 Tx 신호를 완전히 제한(restrict)하는 방법. How to completely restrict the Tx signal before cell selection
Control을 위한 최소한의 Tx 신호도 전송하는 것을 제한하고, PBCH 정보만을 활용한다. 이 경우에도, RRC 연결 Fail 시 재시도가 추가되지만, 5G NR 송신 신호 노출에 대한 높은 safety 레벨을 제공할 수 있다.It limits transmission of the minimum Tx signal for control and utilizes only PBCH information. Even in this case, a retry is added when the RRC connection fails, but a high safety level for 5G NR transmission signal exposure can be provided.
방법2 Method 2 . RRC 연결 이후 최소한의 Tx 신호 전송만 허용하는 방법. How to allow only minimum Tx signal transmission after RRC connection
RRC 연결(connection)된 경우, 수신 신호 품질, 예컨대, RSRP를 활용한다. 구체적으로, RRC 상태 보고(report)를 위한 Tx 신호 전송만 허용하고, internet service 등을 위한 user data 전송은 5G CPE 설치가 완료된 경우에만 허용한다.In the case of RRC connection, the received signal quality, for example, RSRP is utilized. Specifically, only Tx signal transmission for RRC status report is allowed, and user data transmission for internet service, etc. is allowed only when 5G CPE installation is completed.
짧은 시간 동안 특정 제어 정보에 대한 Tx 신호 전송은 허용하므로, 방법 1에 비해 완전한 Tx disable 방식은 아니다. 하지만, 링크 품질이 양호하지 않은 경우에도 링크 연결을 유지할 수 있다. 또한, 5G CPE의 포지셔닝 및 틸트와 같은 위치 선정 시, 5G CPE 설치의 높은 성공률을 제공할 수 있다.Since Tx signal transmission for specific control information for a short time is allowed, it is not a complete Tx disable method compared to Method 1. However, the link connection can be maintained even when the link quality is not good. In addition, when selecting a location such as positioning and tilting of 5G CPE, it can provide a high success rate of 5G CPE installation.
한편, 도 5a, 도 5b 및 도 8b를 참조하여, 본 발명에 따른 5G 통신 중계 장치, 즉 5G CPE의 제어 동작에 대해 설명하면 다음과 같다. 이와 관련하여, 송수신부(520)는 무선 신호, 특히 5G NR 신호를 송신 및 수신하도록 구성된다. 한편, 제어부(510)는 송수신부(520)와 연결되고, 기지국으로부터 수신된 무선 신호를 전자 기기(100)로 제공하도록 구성된다. 또한, 제어부(510)는 테스트 모드(test mode)에서 셀 탐색(cell search)이 개시(initiate)된 경우, 무선 신호가 송수신부(520)를 통해 송신되지 않도록 제어할 수 있다.Meanwhile, a control operation of a 5G communication relay device, that is, a 5G CPE, according to the present invention will be described with reference to FIGS. 5A, 5B, and 8B. In this regard, the transceiving unit 520 is configured to transmit and receive radio signals, in particular 5G NR signals. Meanwhile, the control unit 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. In addition, when a cell search is initiated in a test mode, the controller 510 may control a radio signal not to be transmitted through the transmission/reception unit 520.
이와 관련하여, 제어부(510)는 물리 하향링크 공유 채널(physical downlink shared channel: PDSCH)를 통해 시스템 정보 블록(system information block: SIB)을 수신(S324)할 수 있다. 이에 따라, 제어부(510)는 SIB가 수신된 경우, 무선 신호가 송수신부(520)를 통해 송신되지 않도록 TX 비활성화(Disable) 과정(process)을 수행할 수 있다.In this regard, the controller 510 may receive a system information block (SIB) through a physical downlink shared channel (PDSCH) (S324). Accordingly, when the SIB is received, the controller 510 may perform a TX disable process so that the radio signal is not transmitted through the transceiver 520.
한편, TX 비활성화(Disable)가 개시되는 시점이 SIB가 수신된 시점으로 한정되는 것은 아니다. 대안으로, TX 비활성화(Disable)가 개시되는 시점이 MIB가 수신된 시점에서 이루어질 수 있다. 이와 관련하여, 제어부(510)는 물리 방송 채널(physical broadcast channel: PBCH)를 통해 마스터 정보 블록(master information block: MIB)을 수신(S323)할 수 있다. 이에 따라, 제어부(510)는 MIB가 수신된 경우, 무선 신호가 송수신부(520)를 통해 송신되지 않도록 TX 비활성화(Disable) 과정(process)을 수행할 수 있다.Meanwhile, the timing at which TX disable is initiated is not limited to the timing at which the SIB is received. Alternatively, a time point at which TX disable is initiated may be made at a time point at which the MIB is received. In this regard, the control unit 510 may receive (S323) a master information block (MIB) through a physical broadcast channel (PBCH). Accordingly, when the MIB is received, the controller 510 may perform a TX disable process so that the radio signal is not transmitted through the transceiver 520.
이러한 TX 비활성화(Disable) 과정은 5G 통신 중계 장치의 설치(installation)가 완료되면 종료될 수 있다. 이에 따라, 5G 통신 중계 장치의 설치가 완료되면, TX 활성화(Enable) 과정이 수행될 수 있다. 따라서, 제어부(510)는 5G 통신 중계 장치의 설치(installation)가 완료된 것으로 판단되면 무선 신호가 송수신부(520)를 통해 송신될 수 있도록 TX 활성화(Enable) 과정을 수행할 수 있다.This TX disable process may be terminated when the installation of the 5G communication relay device is completed. Accordingly, when the installation of the 5G communication relay device is completed, a TX activation process may be performed. Accordingly, when it is determined that the installation of the 5G communication relay device has been completed, the controller 510 may perform a TX activation process so that a radio signal can be transmitted through the transceiver 520.
한편, 전술한 방법 1이 사용되는 경우에도, 무선 자원 제어(radio resource control: RRC) 연결(connection)이 실패(fail)한 경우, RRC 재설정(re-establishment)을 위한 제어 신호는 송신될 수 있다. 이를 위해, 제어부(510)는 무선 자원 제어(radio resource control: RRC) 연결(connection)이 실패(fail)한 경우, RRC 재설정(re-establishment)을 위한 제어 신호는 송신될 수 있도록 제어할 수 있다. Meanwhile, even when the above-described Method 1 is used, when a radio resource control (RRC) connection fails, a control signal for RRC re-establishment may be transmitted. . To this end, the control unit 510 may control a control signal for RRC re-establishment to be transmitted when a radio resource control (RRC) connection fails. .
구체적으로, 제어부(510)는 무선 자원 제어(radio resource control: RRC) 연결(connection)이 실패(fail)한 경우, RRC 재설정(re-establishment)을 위한 제어 신호는 송신될 수 있도록 기지국으로 RRC 재설정 요청을 송수신부(520)를 통해 기지국으로 전송할 수 있다. 이러한 RRC 재설정 요청은 5G 기지국으로 전송되지만, 5G non-stand-alone(NSA) 구조에서는 4G 기지국 및/또는 5G 기지국으로 전송될 수 있다. 이에 따라, RRC 연결 요청의 신뢰성을 향상시키고 빠른 시간 내에 RRC 연결이 재설정될 수 있다는 장점이 있다.Specifically, the control unit 510 resets the RRC to the base station so that when a radio resource control (RRC) connection fails, a control signal for re-establishment can be transmitted. The request may be transmitted to the base station through the transceiver 520. The RRC reconfiguration request is transmitted to the 5G base station, but may be transmitted to the 4G base station and/or the 5G base station in the 5G non-stand-alone (NSA) structure. Accordingly, there is an advantage in that the reliability of the RRC connection request can be improved and the RRC connection can be reset within a short time.
이에 따라, RRC 연결이 성공하여 RRC 연결 상태(RRC-connected state)가 된 경우, 다시 TX 비활성화(Disable) 상태를 유지할 필요가 있다. 따라서, 제어부(510)는 RRC 연결이 성공하여 RRC 연결 상태(RRC-connected state)가 된 경우, 테스트 모드에 따른 테스트 과정이 완료될 때까지 무선 신호가 송수신부(520)를 통해 송신되지 않도록 제어할 수 있다.Accordingly, when the RRC connection is successful and becomes an RRC-connected state, it is necessary to maintain the TX disabled state again. Therefore, when the RRC connection is successful and the RRC-connected state is reached, the control unit 510 controls the radio signal to not be transmitted through the transceiver 520 until the test process according to the test mode is completed. can do.
한편, 방법 2와 같이 예외적으로 특정 제어 정보의 송신은 허용하는 경우, 제어 정보와 사용자 데이터에 대해 다른 방식이 적용될 수 있다. 이와 관련하여, 제어부(510)는 RRC 연결 상태(RRC-connected state)에서 RRC 상태 보고(state report)를 위한 제어 데이터를 위한 제1 무선 신호는 송신되도록 송수신부(520)를 제어할 수 있다. 반면에, 제어부(510)는 사용자 데이터(user data)를 위한 제2 무선 신호는 송신되지 않도록 송수신부(520)를 제어할 수 있다.On the other hand, when the transmission of specific control information is exceptionally allowed as in Method 2, different methods may be applied to the control information and user data. In this regard, the control unit 510 may control the transmission/reception unit 520 to transmit the first radio signal for control data for an RRC state report in an RRC-connected state. On the other hand, the control unit 510 may control the transmission/reception unit 520 so that the second radio signal for user data is not transmitted.
이와 관련하여, '송수신부(520)를 제어'의 의미는 제어부(510)가 데이터를 포함하는 신호를 생성하지 않는다는 의미로 해석 가능하다. 또한, 제어부(510)가 데이터를 포함하는 신호를 생성하지만 데이터를 포함하는 신호를 송수신부(520)로 전달하지 않는다는 의미로 해석 가능하다. 또한, 제어부(510)가 데이터를 포함하는 신호를 전달하지만, 송수신부(520)가 상기 신호를 안테나를 통해 기지국 또는 주변 전달기기로 송신하지 않는다는 의미로 해석 가능하다. 이와 관련하여, 송수신부(520)의 전력 증폭기 전단 또는 후단에 구비되는 스위치를 오프(OFF)하여 상기 신호가 증폭되지 않거나 안테나를 통해 송신되지 않도록 제어할 수 있다.In this regard, the meaning of “controlling the transmission/reception unit 520” can be interpreted as meaning that the controller 510 does not generate a signal including data. In addition, it can be interpreted as meaning that the control unit 510 generates a signal including data, but does not transmit a signal including data to the transmission/reception unit 520. In addition, it can be interpreted as meaning that the control unit 510 transmits a signal including data, but the transmission/reception unit 520 does not transmit the signal to a base station or a peripheral transmission device through an antenna. In this regard, by turning off a switch provided at the front or rear end of the power amplifier of the transmission/reception unit 520, the signal may not be amplified or transmitted through an antenna.
한편, 본 발명에 따른 5G CPE의 신호 송신 제어 방법은 5G non-stand-alone(NSA) 구조 및 5G stand-alone(SA) 구조에서 모두 지원될 수 있다. 이와 관련하여, 도 9a는 5G NSA 구조에서 무선 인터페이스 간 핸드오버를 나타낸다. 반면에, 도 9b는 5G SA 구조에서 무선 인터페이스 간 핸드오버를 나타낸다.Meanwhile, the method for controlling signal transmission of 5G CPE according to the present invention may be supported in both a 5G non-stand-alone (NSA) structure and a 5G stand-alone (SA) structure. In this regard, FIG. 9A shows handover between air interfaces in a 5G NSA structure. On the other hand, FIG. 9B shows handover between air interfaces in a 5G SA structure.
도 9a (a)는 NSA 구조에서 5G UE 또는 5G CPE가 4G 기지국에서 5G 기지국으로 핸드오버 하는 일 실시예를 나타낸다. 여기서, LTE는 4G 기지국을 의미하고, eNB로 지칭할 수 있다. 반면에, gNB는 5G NR 기지국에 해당한다. 도 9a (a)를 참조하면, NSA 네트워크(NW)에 의한 LTE-NR 핸드오버가 evolved packet core (EPC) 제어 하에 이루어진다. 여기서, EPC는 4G 코어 네트워크에 해당하고, 4G 기지국과 5G 기지국이 모두 EPC에 연결될 수 있다. 한편, 5G UE 또는 5G CPE가 5G 기지국으로 핸드오버 된 경우에도, 5G UE 또는 5G CPE는 eNB와 gNB를 통해 이중 연결 상태, 즉 EUTRAN NR Dual Connectivity (EN-DC)를 유지할 수 있다.9a (a) shows an embodiment in which a 5G UE or 5G CPE handovers from a 4G base station to a 5G base station in an NSA structure. Here, LTE refers to a 4G base station and may be referred to as an eNB. On the other hand, gNB corresponds to a 5G NR base station. 9A (a), LTE-NR handover by an NSA network (NW) is performed under evolved packet core (EPC) control. Here, the EPC corresponds to a 4G core network, and both the 4G base station and the 5G base station may be connected to the EPC. On the other hand, even when the 5G UE or 5G CPE is handed over to the 5G base station, the 5G UE or 5G CPE can maintain a dual connectivity state, that is, EUTRAN NR Dual Connectivity (EN-DC) through the eNB and gNB.
반면에, 도 9a (b)는 NSA 구조에서 5G UE 또는 5G CPE가 4G 기지국에서 5G 기지국으로 핸드오버 하는 다른 실시예를 나타낸다. 여기서, eLTE는 4G 기지국을 의미하고, eNB로 지칭할 수 있다. 반면에, gNB는 5G NR 기지국에 해당한다. 도 9a (b)를 참조하면, NSA 네트워크(NW)에 의한 LTE-NR 핸드오버가 5G Core (5GC) 제어 하에 이루어진다. 여기서, 5GC는 5G 코어 네트워크에 해당하고, 4G 기지국과 5G 기지국이 모두 5GC에 연결될 수 있다. 한편, 5G UE 또는 5G CPE가 5G 기지국으로 핸드오버 된 경우에도, 5G UE 또는 5G CPE는 eNB와 gNB를 통해 이중 연결 상태, 즉 EUTRAN NR Dual Connectivity (EN-DC)를 유지할 수 있다.On the other hand, Figure 9a (b) shows another embodiment of a 5G UE or 5G CPE handover from a 4G base station to a 5G base station in the NSA structure.

For example, the controller 510 may control the transceiver 520 to transmit control information for searching and selecting an NR cell through a 4G radio signal.
전술한 방법 1과 관련하여, 5G non-stand-alone(NSA) 구조 및 5G stand-alone(SA) 구조에서 다음과 같은 방식으로 Tx 신호 송신을 제한할 수 있다. 구체적으로, 5G non-stand-alone(NSA) 구조 및 5G stand-alone(SA) 구조에서 LTE에서 new radio (NR)로 무선 인터페이스가 변경되어 NR 셀 탐색(NR cell search)이 개시된 경우, 제어부(510)는 다음과 같이 동작을 수행할 수 있다. 이와 관련하여, 제어부(510)는 물리 하향링크 공유 채널(physical downlink shared channel: PDSCH)를 통해 시스템 정보 블록(system information block: SIB)을 수신할 수 있다. 또한, 제어부(510)는 SIB가 수신된 경우, 상기 테스트 모드에 따른 테스트 과정이 완료될 때까지 무선 신호가 송수신부(520)를 통해 송신되지 않도록 제어할 수 있다. 이와 관련하여, 전술한 방법 1과 같은 방식을 사용하여 5G Tx 신호의 송신을 가능한 방지할 수 있다는 장점이 있다.Regarding the above-described Method 1, in the 5G non-stand-alone (NSA) structure and the 5G stand-alone (SA) structure, Tx signal transmission may be restricted in the following manner. Specifically, when the radio interface is changed from LTE to new radio (NR) in the 5G non-stand-alone (NSA) structure and the 5G stand-alone (SA) structure, and NR cell search is initiated, the controller ( 510 may perform an operation as follows. In this regard, the controller 510 may receive a system information block (SIB) through a physical downlink shared channel (PDSCH). In addition, when the SIB is received, the controller 510 may control a radio signal not to be transmitted through the transceiving unit 520 until a test process according to the test mode is completed.

반면에, LTE Attach 및 PDN 셋업 단계(S330)를 통해 PDN (Packet Data Network) 어태치(attach)가 완료되기 이전에도 RRC 연결 상태(RRC-connected state)에서 NR 측정(measurement) 및 NR 측정 보고를 위한 제어 데이터는 전송될 수 있다. 여기서, 제어 데이터는 물리 상향링크 제어 채널(physical uplink control channel: PUCCH)을 통해 제1 무선 신호로 전송될 수 있다. 따라서, 제어부(510)는 RRC 연결 상태(RRC-connected state)에서 NR 측정(measurement) 및 NR 측정 보고를 위한 제어 데이터를 제1 무선 신호를 통해 송신할 수 있다.On the other hand, even before the PDN (Packet Data Network) attach is completed through the LTE Attach and PDN setup step (S330), NR measurement and NR measurement report are performed in the RRC-connected state. Control data for can be transmitted. Here, the control data may be transmitted as a first radio signal through a physical uplink control channel (PUCCH). Accordingly, the controller 510 may transmit control data for NR measurement and NR measurement report through the first radio signal in the RRC-connected state.
도 12b를 참조하면, 5G UE 또는 5G CPE가 LTE 연결 상태에서, NR coverage에 진입한 경우, 5G UE 또는 5G CPE는 eNB로부터 RRCConnectionReconfiguration 메시지를 수신한다. 이와 관련하여, 도 10b의 전술된 방법 1에서는 Control data 전송을 포함하여 모든 Tx 전송을 제한한다. 하지만, 도 12b의 방법 2에서는 짧은 시간 동안 특정 control data 전송은 허용한다.Referring to FIG. 12B, when a 5G UE or 5G CPE enters NR coverage in an LTE connection state, the 5G UE or 5G CPE receives an RRCConnectionReconfiguration message from the eNB. In this regard, in Method 1 described above of FIG. 10B, all Tx transmissions including control data transmission are restricted. However, in Method 2 of FIG. 12B, specific control data transmission is allowed for a short time.
도 10b의 방법 1과 도 12b의 방법 2에 의한 차이점은 control data의 전송 여부이다. 반면에, 도 10b의 방법 1과 도 12b의 방법 2의 공통점은 5G CPE의 최적 설치 위치와 방향을 탐색하는 동안 user data의 전송은 차단된다는 것이다.The difference between Method 1 of FIG. 10B and Method 2 of FIG. 12B is whether control data is transmitted. On the other hand, the common point between Method 1 of FIG. 10B and Method 2 of FIG. 12B is that transmission of user data is blocked while searching for the optimal installation location and direction of 5G CPE.
구체적으로, 도 12b를 참조하면, 5G UE 또는 5G CPE는 제1 기지국, 즉 마스터 기지국(MeNB)을 통해 RRCConnectionReconfiguration 메시지를 수신할 수 있다. 여기서, 제1 기지국, 즉 마스터 기지국(MeNB)은 4G LTE 기지국일 수 있다. 이에 따라, RRCConnectionReconfiguration 메시지를 수신한 5G UE 또는 5G CPE는 NR Measurements를 수행할 수 있다. Specifically, referring to FIG. 12B, a 5G UE or a 5G CPE may receive an RRCConnectionReconfiguration message through a first base station, that is, a master base station (MeNB). Here, the first base station, that is, the master base station (MeNB) may be a 4G LTE base station. Accordingly, the 5G UE or 5G CPE receiving the RRCConnectionReconfiguration message may perform NR Measurements.
이와 관련하여, 5G UE 또는 5G CPE의 제어부(510)는 NR Measurements 과정과 같이 Tx 비활성화(Disable) 절차 동안에도 특정 Control information 전송을 위한 Tx 신호 전송은 허용할 수 있다.In this regard, the control unit 510 of the 5G UE or 5G CPE may allow transmission of a Tx signal for transmission of specific control information even during a Tx disable procedure like the NR Measurements process.
따라서, 수신 신호 품질에 기반하여 5G CPE가 NR 셀에 등록(register) 가능한지 여부를 판단하지 않고, NR Measurements report를 제1 기지국을 통해 제2 기지국으로 전달할 수 있다. 여기서, NR Measurements report는 MeasurementReport 메시지를 통해 전달될 수 있다. 여기서, 제2 기지국, 즉 세컨더리 기지국(SeNB)은 5G NR 기지국일 수 있다. 5G NSA 구조에서 5G NR 기지국은 세컨더리 기지국(SeNB)으로 해석될 수 있다. 또한, MeasurementReport 메시지를 수신한 제1 기지국, 즉 마스터 기지국(MeNB)은 제2 기지국, 즉 세컨더리 기지국(SeNB)로 SCG 설정 정보 메시지, 즉 SCGConfigInfoGUTRA 메시지를 전달할 수 있다.Accordingly, the NR Measurements report may be transmitted to the second base station through the first base station without determining whether the 5G CPE can be registered in the NR cell based on the received signal quality. Here, the NR Measurements report may be delivered through a MeasurementReport message. Here, the second base station, that is, the secondary base station (SeNB) may be a 5G NR base station. In the 5G NSA structure, the 5G NR base station can be interpreted as a secondary base station (SeNB). In addition, the first base station receiving the MeasurementReport message, that is, the master base station (MeNB), may transmit the SCG configuration information message, that is, the SCGConfigInfoGUTRA message, to the second base station, that is, the secondary base station (SeNB).

NR 측정 과정(S130)에서, 수신 신호 품질, 즉 RSRP가 제1 임계치(Threshold #1) 이상이면, 테스트 모드를 종료하고 TX 활성화(Enable) 절차(S150)를 수행하도록 제어할 수 있다. TX 활성화(Enable) 절차(S150)에서, NR 측정 보고 과정이 수행될 수 있다. 5A, 5B, 6, 8A, 8B, 10A, and 13, the controller 510 of the 5G CPE may perform the NR measurement process (S130) in the Tx disable state. In the NR measurement process (S130), if the received signal quality, that is, RSRP is greater than or equal to the first threshold (Threshold #1), control to terminate the test mode and perform the TX enable procedure (S150). In the TX activation procedure (S150), an NR measurement report process may be performed.
한편, 수신 신호 품질, 즉 RSRP가 제1 임계치(Threshold #1) 미만이고 제2 임계치(Threshold #2) 이상이면, 제어부(510)는 틸팅 절차(S140)를 수행하도록 제어할 수 있다. 수신 신호 품질에 따라 LED 색을 변경하여 표시하는 LED 제어가 수행될 수 있다.On the other hand, if the received signal quality, that is, RSRP is less than the first threshold (Threshold #1) and the second threshold (Threshold #2) or more, the control unit 510 may control to perform the tilting procedure (S140). LED control that changes and displays the LED color according to the received signal quality can be performed.
반면에, 수신 신호 품질, 즉 RSRP가 제2 임계치(Threshold #2) 미만이면, 제어부(510)는 설치 장소를 이동하여 재설치 절차를 수행하도록 제어(S160)할 수 있다. 재설치 절차가 수행되어야 하는 것을 사용자 또는 설치 관리자에게 알리기 위해 수신 신호 품질에 따라 LED 색을 변경하여 표시하거나 또는 LED 색을 달리하여 blinking하는 LED 제어가 수행될 수 있다.On the other hand, if the received signal quality, that is, RSRP, is less than the second threshold (Threshold #2), the control unit 510 may move the installation location to perform a re-installation procedure (S160). In order to inform the user or the installer that the re-installation procedure should be performed, the LED control may be performed by changing the LED color according to the received signal quality and displaying or blinking by changing the LED color.
결론적으로, 도 11과 도 13의 5G CPE 동작은 NR measurement이후에 수행되는 CPE 동작 시퀀스라는 점에서 유사하다. 하지만, 도 13의 5G CPE 동작은 RSRP를 기반으로 5G CPE가 NR 커버리지 영역에 있는 지 여부를 판단하는 점에서 차별점이 있다.In conclusion, the 5G CPE operation of FIGS. 11 and 13 is similar in that it is a CPE operation sequence performed after NR measurement. However, the 5G CPE operation of FIG. 13 has a difference in determining whether the 5G CPE is in the NR coverage area based on RSRP.

OFDM 스트림은 다중 공간 스트림을 생성하기 위해 공간적으로 프리코딩된다. 각각의 공간 스트림은 개별 Tx/Rx 모듈(또는 송수신기,915)를 통해 상이한 안테나(916)에 제공될 수 있다. 각각의 Tx/Rx 모듈은 전송을 위해 각각의 공간 스트림으로 RF 반송파를 변조할 수 있다. 제 2 통신 장치에서, 각각의 Tx/Rx 모듈(또는 송수신기,925)는 각 Tx/Rx 모듈의 각 안테나(926)을 통해 신호를 수신한다. 각각의 Tx/Rx 모듈은 RF 캐리어로 변조된 정보를 복원하여, 수신(RX) 프로세서(923)에 제공한다. RX 프로세서는 layer 1의 다양한 신호 프로세싱 기능을 구현한다. RX 프로세서는 제 2 통신 장치로 향하는 임의의 공간 스트림을 복구하기 위해 정보에 공간 프로세싱을 수행할 수 있다. 만약 다수의 공간 스트림들이 제 2 통신 장치로 향하는 경우, 다수의 RX 프로세서들에 의해 단일 OFDMA 심볼 스트림으로 결합될 수 있다.

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 can 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.
UL(제 2 통신 장치에서 제 1 통신 장치로의 통신)은 제 2 통신 장치(920)에서 수신기 기능과 관련하여 기술된 것과 유사한 방식으로 제 1 통신 장치(910)에서 처리된다. 각각의 Tx/Rx 모듈(925)는 각각의 안테나(926)을 통해 신호를 수신한다. 각각의 Tx/Rx 모듈은 RF 반송파 및 정보를 RX 프로세서(923)에 제공한다. 프로세서 (921)는 프로그램 코드 및 데이터를 저장하는 메모리 (924)와 관련될 수 있다. 메모리는 컴퓨터 판독 가능 매체로서 지칭될 수 있다.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.
