Abstract

A synchronous block for controlling forward signal delay in a mobile communication base station and a synchronous signal supply method for controlling the forward signal delay in the base station are provided to allow the synchronous block to transmit the second frame synchronous signal for compensating delay to a modem, thus a complex operation due to a time advance function does not have to be performed when the modem is developed. A synchronization generator(211a) generates the first frame synchronous signal identical with frame synchronization of a forward signal, and sends the generated frame synchronous signal to a delayer and RF(Radio Frequency) block(214). A time advance unit(211b) generates the second frame synchronous signal by advancing the first frame synchronous signal outputted from the synchronization generator(211a) for a certain time, and sends the second frame synchronous signal to a modem(212).

본 발명은 이동통신 기지국에서 순방향 신호 딜레이 제어를 위한 동기블록 및 동기신호 제공 방법에 관한 것이다.The present invention relates to a synchronization block and a synchronization signal providing method for controlling a forward signal delay in a mobile communication base station.

일반적으로 이동통신 시스템에서는, 모뎀에서 출력되는 기저대역 신호를 RF(Radio Frequency : 무선주파수)블록에서 반송파에 실어 안테나를 통해 공중으로 전파하여 단말기에 전송한다. 또한 이러한 기지국의 설치에 의해서도 커버되지 않는 전파 음영지역에 서비스를 제공하기 위해 중계기를 사용하는데, 이러한 중계기의 설치는 기지국의 설치보다 비용면에서 훨씬 저렴하기 때문에 널리 보급되고 있다.In general, in a mobile communication system, a baseband signal output from a modem is mounted on a carrier wave in an RF block and propagated to the air through an antenna to be transmitted to a terminal. In addition, a repeater is used to provide a service in a radio shadow area which is not covered by the installation of such a base station. The installation of such a repeater is widely used because it is much cheaper than the installation of a base station.

중계기 연결 방식은 기지국의 RF블록의 전단 또는 후단에서 기지국의 순방향 신호를 분배하여 중계기측에 전달하여 전파음영지역의 단말기에 전송하는데, 이때 기지국의 안테나에서 출력되는 신호의 송신 시각과 중계기의 안테나에서 출력되는 신호의 송신 시각이 오차 허용범위 내에서 같아야 한다. 그러나 기지국 경로와 중계기 경로는 딜레이의 차이가 발생할 수 있으며, 특히 중계기 경로에서 발생하는 추가적인 딜레이가 서비스 반경을 제한하는 문제점을 발생시킬 수도 있다.The repeater connection method distributes the forward signal of the base station at the front end or the rear end of the base station's RF block and transmits it to the repeater side for transmission to the terminal of the radio shade area. The transmission time of the output signal should be the same within the tolerance. However, there may be a delay difference between the base station path and the repeater path, and in particular, an additional delay occurring in the repeater path may cause a problem of limiting the service radius.

이러한 문제점을 해결하기 위하여, 중계기 경로에서 지연되는 만큼의 시간을 기지국의 모뎀에서 미리 발생시키고(Time Advance), 기지국에서는 딜레이어를 구비하여 중계기 경로에서 지연되는 만큼의 시간을 지연시키도록 하여, 기지국에서 출력되는 신호와 중계기에서 출력되는 신호가 동일한 시각에 출력되도록 하는 이른바 타임어드밴스(Time Advance)를 구현한 기술이 제시된 바 있다.In order to solve this problem, a time delay in the repeater path is generated in advance in the modem of the base station (Time Advance), and the base station is provided with a delay so as to delay the delay in the repeater path in the base station. The technology that implements the so-called Time Advance has been proposed to output the signal from the repeater and the signal output from the repeater at the same time.

도1은 종래의 타임어드밴스(Time Advance)를 구현하여 순방향 신호의 딜레이를 제어하는 이동통신 시스템을 설명하기 위한 도면이다. 도1에 도시된 바와 같이, 기지국(110)의 동기생성부(111)에서는 무선규격상에 정해진 순방향 프레임 동기와 일치하는 프레임동기신호를 생성하여 모뎀(112)과 딜레이어 및 RF블록(114)에 제공하고, 모뎀(112)은 버퍼(112a)를 제어하여 순방향 신호를 정해진 프레임 동기보다 일정 시간 앞당겨 출력하도록 한다. 이때 중계기 경로에서 생기는 딜레이 만큼을 정해진 프레임 동기보다 앞당겨질 수 있도록 버퍼(112a)를 제어한다. 또한 딜레이어 및 RF블록(114)에서도, 중계기 경로에서 생기는 딜레이 만큼 순방향 신호를 지연시킬 수 있도록 구현한다. 따라서, 모뎀에서 정해진 프레임 동기보다 일정 시간 앞당겨 출력된 순방향 신호는 딜레이어 및 RF블록(114)에서 앞당겨진 시간만큼 지연되어 기지국 안테나를 통해 출력되고, 또한, 디바이더(113)를 통해 모뎀(112)에서 출력된 신호가 중계기(120) 경로를 지나면서, 앞당겨진 시간만큼 지연되어 중계기 안테나를 통해 출력된다. 따라서, 기지국 안테나 및 중계기 안테나에서 출력되는 신호들은 무선규격상에 정해진 프레임 동기에 맞게, 적절한 시각에 출력된다.1 is a diagram for describing a mobile communication system for controlling a delay of a forward signal by implementing a conventional time advance. As shown in FIG. 1, the synchronization generating unit 111 of the base station 110 generates a frame synchronization signal corresponding to the forward frame synchronization specified in the radio standard, and transmits it to the modem 112, the delay, and the RF block 114. In addition, the modem 112 controls the buffer 112a to output the forward signal a predetermined time ahead of a predetermined frame synchronization. At this time, the buffer 112a is controlled to advance the delay in the repeater path by a predetermined frame synchronization. In addition, the delay and the RF block 114 are implemented to delay the forward signal by the delay occurring in the repeater path. Therefore, the forward signal output in advance of the predetermined frame synchronization in the modem is delayed by the delayed time in the delay and RF block 114 and output through the base station antenna, and also in the modem 112 through the divider 113. As the output signal passes through the repeater 120 path, the output signal is delayed by an advanced time and output through the repeater antenna. Therefore, the signals output from the base station antenna and the repeater antenna are output at appropriate times in accordance with the frame synchronization determined in the radio standard.

그러나 종래의 타임어드밴스를 구현하여 순방향 신호의 딜레이를 제어하는 기술에서는 모뎀(112)의 개발시 타임어드밴스 기능에 따른 순방향 신호의 버퍼(112a) 제어 등의 복잡한 동작이 뒷받침되어야 하는 문제점이 있다.However, in the conventional technology for controlling the delay of the forward signal by implementing the time advance, there is a problem that complicated operations such as the control of the forward signal buffer 112a according to the time advance function have to be supported when the modem 112 is developed.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 복잡한 버퍼의 제어 없이도 순방향 신호 딜레이를 제어할 수 있는 기술을 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a technique capable of controlling a forward signal delay without controlling a complicated buffer.

상기 목적을 달성하기 위한 본 발명에 따른 이동통신 기지국에서 순방향 신호 딜레이 제어를 위한 동기블록은, 순방향 신호의 프레임 동기와 일치하는 제1프레임동기신호를 생성하여, 딜레이어 및 RF블록측으로 보내는 동기생성부; 및 상기 동기생성부에서 출력되는 제1프레임동기신호를 일정시간 앞당겨 제2프레임동기신호를 생성하고, 상기 제2프레임동기신호를 상기 모뎀측으로 보내는 타임어드밴스부; 를 포함한다.In the mobile communication base station according to the present invention for achieving the above object, a sync block for forward signal delay control generates a first frame sync signal that matches frame sync of a forward signal, and sends it to a delay and an RF block side. ; And a time advance unit generating a second frame synchronization signal by advancing the first frame synchronization signal output from the synchronization generation unit for a predetermined time and sending the second frame synchronization signal to the modem. It includes.

또한, 상기 목적을 달성하기 위한 본 발명에 따른 이동통신 기지국에서 순방향 신호 딜레이 제어를 위한 동기 제공 방법은, 순방향 신호의 프레임 동기와 일치하는 제1프레임동기신호를 생성하는 제1프레임동기신호생성단계; 상기 제1프레임동기신호생성단계에서 생성된 상기 제1프레임동기신호를 딜레이어 및 RF블록측으로 보내는 제1프레임동기신호제공단계; 상기 제1프레임동기신호생성단계에서 생성된 상기 제1프레임동기신호를 일정시간 앞당겨 제2프레임동기신호를 생성하는 제2프레임동기신호생성단계; 및 상기 제2프레임동기신호생성단계에서 생성된 상기 제2프레임동기신호를 상기 모뎀측으로 보내는 제2프레임동기신호제공단계; 를 포함한다.In addition, the synchronization providing method for the control of the forward signal delay in the mobile communication base station according to the present invention for achieving the above object, the first frame synchronization signal generating step of generating a first frame synchronization signal matching the frame synchronization of the forward signal; ; A first frame synchronization signal providing step of sending the first frame synchronization signal generated in the first frame synchronization signal generation step to a delay and an RF block side; A second frame synchronous signal generation step of generating a second frame synchronous signal by advancing the first frame synchronous signal generated in the first frame synchronous signal generation step for a predetermined time; And a second frame synchronization signal providing step of sending the second frame synchronization signal generated in the second frame synchronization signal generation step to the modem. It includes.

이하에서는 상술한 본 발명에 대하여 보다 구체적으로 이해할 수 있도록 바람직한 실시예를 들어 설명한다.Hereinafter, preferred embodiments will be described so that the present invention described above can be understood in more detail.

도2는 본 발명의 실시예에 따른 순방향 신호 딜레이 제어를 위한 동기블록(211)이 적용된 이동통신 시스템, 즉 기지국(210)과 중계기(220)를 나타낸 도면이다. 도2에 도시된 바와 같이, 이동통신 시스템은, 본 발명에 따른 동기블록(211)를 포함하는 기지국(210), 중계기(220) 및 단말기(미도시)를 포함한다.2 is a diagram illustrating a mobile communication system to which a sync block 211 for forward signal delay control is applied, that is, a base station 210 and a repeater 220 according to an embodiment of the present invention. As shown in FIG. 2, the mobile communication system includes a base station 210, a repeater 220, and a terminal (not shown) including a sync block 211 according to the present invention.

기지국(210)은 동기블록(211), 모뎀(212), 디바이더(213)와 딜레이어 및 RF블록(214)을 포함할 수 있다.The base station 210 may include a sync block 211, a modem 212, a divider 213 and a delay and an RF block 214.

본 발명에 따른 동기블록(211)은 동기생성부(211a) 및 타임어드밴스부(211b)를 포함한다.The sync block 211 according to the present invention includes a sync generator 211a and a time advance unit 211b.

동기생성부(211a)는 순방향 신호의 프레임 동기와 일치하는 제1프레임동기신호를 생성하여, 딜레이어 및 RF블록(214)측으로 보낸다. 제1프레임동기신호는 무선규격에서 요구하는 신호 송신 프레임 시각에 맞춘 신호이며 도4의 (a)에 해당한다. The synchronization generator 211a generates a first frame synchronization signal that matches the frame synchronization of the forward signal, and sends it to the delay and RF block 214. The first frame synchronization signal corresponds to a signal transmission frame time required by the radio standard and corresponds to FIG. 4A.

타임어드밴스부(211b)는 동기생성부(211a)에서 출력되는 제1프레임동기신호를 일정시간 앞당겨(Time Advance) 제2프레임동기신호를 생성하고, 제2프레임동기신호를 모뎀(212)측으로 보낸다. 제2프레임동기신호는 도4의 (b)에 해당한다.The time advance unit 211b generates a second frame synchronization signal by advancing the first frame synchronization signal output from the synchronization generation unit 211a for a predetermined time, and sends the second frame synchronization signal to the modem 212. The second frame synchronization signal corresponds to FIG. 4B.

모뎀(212)은 상위단으로부터 전송되는 순방향 신호를 변조하여 기저대역 신호를 출력한다. 이때 모뎀(212)에서는 제2프레임동기신호에 맞춰 기저대역 신호를 출력하는데, 제2프레임동기신호는 무선규격에서 요구하는 신호 송신 프레임 시각, 즉 제1프레임동기신호보다 소정시간(도4에서 τ에 해당) 앞당겨져 있기 때문에, τ만큼 미리 기저대역신호를 출력한다(도4의 (c)에 해당). 물론 τ는 중계기 경로에서 생기는 딜레이 만큼의 시간이다. 또한 모뎀(212)은 기지국(210)이 설계되는 형태에 따라 다수의 모뎀(212)이 구비될 수도 있는데, 도2에 도시된 모뎀(212)은, 다수의 모뎀(212)을 대표하는 것이지, 하나의 모뎀(212)에만 국한된 것은 아니다.The modem 212 modulates a forward signal transmitted from an upper end and outputs a baseband signal. At this time, the modem 212 outputs a baseband signal in accordance with the second frame synchronization signal. The second frame synchronization signal is a predetermined time than the signal transmission frame time required by the radio standard, that is, the first frame synchronization signal (τ in FIG. 4). The baseband signal is output in advance by τ (corresponding to Fig. 4C). Of course, τ is equal to the time delay in the repeater path. In addition, the modem 212 may be provided with a plurality of modems 212 according to the design of the base station 210. The modem 212 shown in FIG. 2 represents a plurality of modems 212, It is not limited to one modem 212.

디바이더(213)는 모뎀(212)으로부터 출력되는 기저대역 신호를 분할하여 딜레이어 및 RF블록(214)측과 중계기(220)측으로 전송한다.The divider 213 divides the baseband signal output from the modem 212 and transmits the divided baseband signal to the delay and RF block 214 side and the repeater 220 side.

딜레이어 및 RF블록(214)은, 동기생성부(211a)에서 출력되는 제1프레임동기신호에 맞춰 동작을 하게 되며, 디바이더(213)로부터 분할되어 오는 순방향의 기저대역 신호를 소정시간 지연시키며, 높은 주파수에 실어 기지국 안테나를 통해 공중으로 전파하여 단말기에 전송할 수 있도록 한다. 즉 딜레이어 및 RF블록(214)은, 딜레이어(Delayer), 주파수상향변환기(Up Converter), 디지털-아날로그변환기(Digital to Analog Converter) 및 전력증폭기(Power Amplifier Unit) 등의 순방향 신호처리 수단을 모두 포함할 수 있는 것이며, 또한 역방향 신호처리를 위한 저잡음증폭기(Low Noise Amplifer), 아날로그-디지털변환기(Analog to Digital Converter) 및 주파수하향변환기(Down Converter) 등도 포함할 수 있다. 또한 딜레이어 및 RF블록(214)에서 순방향 신호를 지연시키는 시간은 τ만큼의 시간, 즉 중 계기 경로에서 생기는 딜레이 만큼의 시간이 지연될 수 있도록 설계한다.The delay and the RF block 214 operates in accordance with the first frame synchronization signal output from the synchronization generator 211a, and delays a forward baseband signal split from the divider 213 for a predetermined time and is high. It is loaded on the frequency to transmit to the terminal through the base station antenna to the air. That is, the delay and the RF block 214 may include forward signal processing means such as a delay (Delayer), a frequency converter (Up Converter), a digital-to-analog converter (Digital to Analog Converter), and a power amplifier unit. It may include all, and may also include a low noise amplifier (Analog to Digital Converter), a frequency converter (Down Converter), etc. for reverse signal processing. In addition, the delay time of the forward signal in the delay and the RF block 214 is designed such that the time as much as τ, that is, as much as the delay in the medium instrument path, can be delayed.

이하에서는 도3을 참조하여 본 발명의 실시예에 따른 이동통신 기지국에서 순방향 신호 딜레이 제어를 위한 동기신호 제공 방법에 대해 설명하도록 한다.Hereinafter, a method of providing a synchronization signal for controlling a forward signal delay in a mobile communication base station according to an embodiment of the present invention will be described with reference to FIG. 3.

1.제1프레임동기신호생성단계<S310>1.First frame synchronous signal generation step <S310>

순방향 신호의 프레임 동기와 일치하는 제1프레임동기신호를 생성한다. 제1프레임동기신호는 무선규격에서 요구하는 신호 송신 프레임 시각에 맞춘 신호이며 도4의 (a)에 해당한다.A first frame synchronization signal is generated that matches the frame synchronization of the forward signal. The first frame synchronization signal corresponds to a signal transmission frame time required by the radio standard and corresponds to FIG. 4A.

2.제1프레임동기신호제공단계<S320>2.First frame sync signal providing step <S320>

제1프레임동기신호생성단계<S310>에서 생성된 제1프레임동기신호를 딜레이어 및 RF블록(214)측으로 보낸다. The first frame synchronization signal generated in the first frame synchronization signal generation step <S310> is sent to the delay and RF block 214.

3.제2프레임동기신호생성단계<S330>3. Second frame synchronous signal generation step <S330>

제1프레임동기신호생성단계<S310>에서 생성된 제1프레임동기신호를 일정시간(τ) 앞당겨 제2프레임동기신호를 생성한다. 즉, 제2프레임동기신호는 도4의 (b)에 해당한다.The first frame synchronization signal generation step <S310> generates the second frame synchronization signal by advancing the first frame synchronization signal generated by a predetermined time τ. That is, the second frame synchronization signal corresponds to FIG. 4B.

4.제2프레임동기신호제공단계<S340>4. Second frame synchronization signal providing step <S340>

제2프레임동기신호생성단계<S330>에서 생성된 제2프레임동기신호를 모뎀(212)측으로 보낸다.The second frame synchronous signal generation step <S330> sends the second frame synchronous signal to the modem 212 side.

상술한 바와 같이, 본 발명에 따른 동기블록(211)의 타임어드밴스부(211b)에서, 무선규격상 정해진 신호 송신 프레임 시각보다 τ만큼 앞당겨진 제2프레임동기신호를 모뎀(212)측으로 보낼 수 있도록 함으로써, 모뎀(212)에서는 제2프레임동기신호에 맞춰 τ만큼 앞당겨 순방향 신호를 출력할 수 있다. 따라서 중계기(220)에서는 τ만큼 앞당겨진 순방향 신호가 중계기(220) 경로상에서 τ만큼 딜레이 되어, 결국엔 무선규격상 정해진 시간에 중계기 안테나를 통해 순방향 신호를 출력할 수 있는 것이며, 기지국(210)의 딜레이어 및 RF블록(214)에서도 τ만큼 순방향 신호를 지연시켜 기지국 안테나를 통해 출력함으로써, 기지국(210)과 중계기(220)가 동일한 시각, 즉 무선규격상 정해진 시간에 순방향 신호를 출력할 수 있는 것이다(도4의 (d)에 해당).As described above, by allowing the time advance unit 211b of the sync block 211 according to the present invention to transmit the second frame sync signal, which is advanced by τ earlier than the signal transmission frame time determined by the radio standard, to the modem 212 side. In response to the second frame synchronization signal, the modem 212 may output a forward signal by advancing by τ. Therefore, in the repeater 220, the forward signal advanced by τ is delayed by τ on the path of the repeater 220, so that the forward signal can be output through the repeater antenna at a predetermined time in accordance with the radio standard, and the delay of the base station 210 is delayed. In addition, the RF block 214 delays the forward signal by τ and outputs it through the base station antenna, so that the base station 210 and the repeater 220 can output the forward signal at the same time, that is, at a predetermined time according to the radio standard. (Corresponds to (d) of FIG. 4).

이상과 같이, 본 발명에 대한 구체적인 설명은 첨부된 도면을 참조한 실시예에 의해서 이루어졌지만, 상술한 실시 예는 본 발명의 바람직한 예를 들어 설명하였을 뿐이기 때문에, 본 발명이 상기의 실시 예에만 국한되는 것으로 이해되어져서는 아니 되며, 본 발명의 권리범위는 후술하는 청구범위 및 그 등가개념으로 이해되어져야 할 것이다.As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings, but the above-described embodiments have been described by way of example only, and thus the present invention is limited to the above embodiments. It should not be understood that the scope of the present invention is to be understood by the claims and equivalent concepts described below.

이상에서 상세히 설명한 바와 같이 본 발명에 따르면, 동기블록에서 딜레이 보상을 위한 제2프레임동기신호를 모뎀측으로 보낼 수 있도록 함으로써, 모뎀의 개발시 타임어드밴스 기능에 따른 버퍼의 제어 등, 복잡한 동작을 수행하지 않아도 되며, 타임어드밴스를 구현해야하는 경우나, 그렇지 않은 경우에도, 동일한 모뎀을 사용하여, 동기블록의 타임어드밴스부에서 프레임 동기의 조절만으로 모뎀을 제어할 수 있다.As described in detail above, according to the present invention, the second block synchronization signal for delay compensation in the sync block can be sent to the modem side, so that complicated operations such as control of a buffer according to a time advance function are not performed during the development of the modem. Even if it is necessary to implement a time advance or not, the same modem can be used to control the modem only by adjusting frame synchronization in the time advance unit of the sync block.
