    • 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.
    • 目的:提供终端与支持终端之间的直接通信的方法,以通过改善同步信道结构来实现直接通信的终端之间的同步。 构成:使用分配的资源对一个或多个第二终端进行直接通信,用于终端之间的直接通信。 该资源包括用于频率同步和终端之间的时间同步的同步信道。 同步信道包括用于前导码检测,时间偏移估计,频率偏移估计或信道估计的同步信道前同步码。 同步信道前导码是重复基本模式的第一序列或将基本模式与将基本模式相乘的模式(-1)组合的第二序列。 一个或多个OFDM(正交频分复用)符号用于发送同步信道前导码。

    • Provided is an authentication method in a wireless mesh network which can reduce overload and delays in communications during authentication processes by performing authentication between nodes without accessing an authentication server. The authentication method in a wireless mesh network according to an embodiment of the present invention comprises the following steps of: selecting, by a new node, a first adjacent node among at least one adjacent mode and transmitting an authentication request message including a public key of the new node; authenticating, by the first adjacent node, the public key of the new node and transmitting an authentication response message including a public key of the first adjacent node to the new node; and authenticating, by the new node, the public key of the first adjacent node and transmitting an authentication confirmation message to the first adjacent node. [Reference numerals] (103) New node; (105) First adjacent node; (S201) Authentication request message; (S203) Authentication response message; (S205) Authentication confirmation message; (S207) Session key request message; (S209) Session key response message
