Abstract: PURPOSE: A method for performing direct communications between terminals and the terminal supporting the same are provided to obtain synchronization between the terminals performing direct communications by improving a synchronization channel structure. CONSTITUTION: Direct communications is performed with one or more second terminals using allocated resources for the direct communications between terminals. The resources include a synchronous channel which is used for frequency synchronization and time synchronization between the terminals. The synchronization channel includes a synchronization channel preamble which is used for either preamble detection, time offset estimation, frequency offset estimation, or channel estimation. The synchronization channel preamble is either a first sequence repeating a basic pattern or a second sequence combining the basic pattern with a pattern multiplying the basic pattern by (-1). One or more OFDM(orthogonal frequency division multiplexing) symbols are used for transmitting the synchronization channel preamble.

Abstract: A method for providing an MBS(Multicast Broadcast Service) in a communication system is provided to allow multiple base stations to match synchronization of MBS data packets in transmitting the MBS data packets to terminals in a multi-access mode. In order to set up a bearer between an MBS server(140) and an ACR(Access Control Router)(130) and between an RAS(Radio Access System)(120) and the ACR(130) before transmitting an MBS data packet, the MBS server(140) transmits a service start request message by MBS data burst to the ACR(130)(S310). The ACR(130) transmits a service start response message to the MBS server(140), and transfers a service start request message created by changing only a GTP Tunnel ID value to be used between the RAS(120) and the ACR(130) in the service start request message with the other remaining parameters unchanged, to the RAS(120)(S330). The RAS(120) registers a received CID(Connection ID) to a corresponding MBS zone ID and transmits a service start response message to the ACR(130)(S340). Upon receiving the service start response message from the ACR(130), the MBS server(140) transmits MBS data packets to the RAS(120) through the ACR(130)(S350,S360).
Abstract translation: 提供了一种用于在通信系统中提供MBS（Multicast Broadcast Service，组播广播服务）的方法，以允许多个基站在将MBS数据分组发送到多址接入模式的终端时匹配MBS数据分组的同步。 为了在发送MBS数据分组之前在MBS服务器（140）和ACR（接入控制路由器）（130）之间以及RAS（无线接入系统）（120）和ACR（130）之间建立承载， MBS服务器（140）通过MBS数据突发向ACR（130）发送业务开始请求消息（S310）（S310）。 ACR（130）向MBS服务器（140）发送业务开始响应消息，并且通过仅改变要在RAS（120）和ACR（130）之间使用的GTP隧道ID值而创建的业务开始请求消息， 在服务启动请求消息中，其他剩余参数不变，到RAS（120）（S330）。 RAS（120）将接收的CID（连接ID）注册到相应的MBS区域ID，并向ACR（130）发送服务开始响应消息（S340）。 在从ACR（130）接收到服务开始响应消息后，MBS服务器（140）通过ACR（130）将MBS数据分组发送到RAS（120）（S350，S360）。
