Abstract: A mobile relay station (RS) and a handover method for the same are disclosed. If the mobile RS determines handover from an upper base station (BS) to a target BS, the mobile RS receives information representing acceptance of the handover from the upper BS. Then, the mobile RS transmits a service unavailable section to a lower terminal and prevents the handover of the lower terminal which receives the service unavailable section through the mobile RS to the other BS or the other RS. [Reference numerals] (100) Mobile relay base ( relay mode terminal);(200) Lower terminal;(310) Upper base station;(320) Target base station;(S230) Accept existing mobile replay base setting information;(S270) Re-enter network to target base station;(S280) Resume relay mode

Abstract: PURPOSE: A direct communication method and a terminal thereof are provided to acquire synchronization by transmitting reference time to a plurality of terminals. CONSTITUTION: A processor(1310) selects synchronization information acquiring reference time according to the priority of synchronization information. The processor acquires the reference time through the selected synchronization information. The priority is followed by first synchronization information, second synchronization information, and third synchronization information. The first synchronization information received from a base station. The second synchronization information is received from a GPS(Global Positioning System). The third synchronization information is received from a small terminal, the base station, or the GPS. [Reference numerals] (1310) Processor; (1320) Memory; (1330) RF module

Abstract: PURPOSE: A uplink data transmission method in a mobile communication system, base station, and terminal are provided to transmit uplink data without connecting to a network an M2M(Machine to Machine) terminal of an idle mode. CONSTITUTION: When uplink transmission target data is generated in an idle mode, a terminal transmit a ranging request message including a group identifier, or a non-connection transmission indicator, or uplink data(S202,S210). The group identifier is allocated according to each terminal group. The non-connection transmission indicator indicates the transmission of the uplink data in a network non-connection state. The terminal receives a raging response message from the base station(S222).
Abstract translation: 目的：提供移动通信系统，基站和终端中的上行链路数据传输方法，以在不连接到空闲模式的M2M（机器对机器）终端的网络的情况下传送上行链路数据。 构成：当在空闲模式下生成上行链路发送对象数据时，终端发送包括组标识符，非连接发送指示符或上行链路数据的测距请求消息（S202，S210）。 组标识符根据每个终端组分配。 非连接传输指示符指示在网络非连接状态下的上行链路数据的传输。 终端从基站接收肆虐响应消息（S222）。

Abstract: 플래시 아날로그 디지털 변환기는 전압 레벨이 각각 다른 복수의 기준 전압과 아날로그 입력 신호의 차를 각각 증폭한 복수의 제1 신호의 윈도우를 정해진 크기만큼 증가시켜 출력한다. 그리고 출력된 신호를 디지털 신호로 인코딩한다. 이렇게 하면, 복수의 프리앰프의 각 출력 신호의 윈도우의 크기가 커지므로, 복수의 프리앰프 각각의 서로 다른 지연 값에 의해 발생하는 데이터 에러율을 줄일 수 있다.
