Abstract: In a direct communication between terminals, a terminal transmits a synchronization channel preamble part after transmitting a synchronization channel message part including synchronization information. The terminal receives a dedicated channel including a direct communication packet after transmitting the synchronization channel preamble part. A transition time gap for switching from transmission to reception may be inserted to an end of the synchronization channel preamble part.
Abstract translation: 在终端之间的直接通信中，终端在发送包括同步信息的同步信道消息部分之后发送同步信道前导码部分。 在发送同步信道前导码部分之后，终端接收包括直接通信分组的专用信道。 用于从传输切换到接收的转换时间间隙可以插入同步信道前同步码部分的末尾。

Abstract: A mobile relay station (RS) and a handover method thereof are provided. When it is determined that a mobile RS performs handover from a superordinate base station (BS) to a target BS, information indicating admission of handover is received from the superordinate BS. The mobile RS transmits a service unavailability section to a subordinate terminal, whereby the subordinate terminal is prevented from performing handover to a different BS or a different RS.
Abstract translation: 提供了一种移动中继站（RS）及其切换方法。 当确定移动RS执行从上级基站（BS）到目标BS的切换时，从上级BS接收到指示接纳切换的信息。 移动RS将服务不可用部分发送到下级终端，由此防止下级终端对不同的BS或不同的RS进行切换。

Abstract: A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.

Abstract: A multimode apparatus and a communication method thereof are disclosed. If the multimode apparatus is chosen to serve as a relay station due to a base station having a backhaul link problem, it sets up a first relay link with a first base station. Upon receiving a request for releasing the first relay link from the first base station even though the backhaul link is not restored, the multimode apparatus sets up a second relay link with a second base station, or configures and operates a standalone network or an independent network.
Abstract translation: 公开了一种多模式装置及其通信方法。 如果由于具有回程链路问题的基站而选择多模装置作为中继站，则它建立与第一基站的第一中继链路。 即使回程链路没有恢复，一旦接收到从第一基站释放第一中继链路的请求，则多模设备与第二基站建立第二中继链路，或者配置和操作独立网络或独立网络 。

Abstract: A communication method of a terminal that can operate in a relay mode or a base station mode is provided. When the terminal, having received a service from a first base station, detects that a service connection to the first base station is unavailable, the terminal searches for a second base station, which is an available neighboring base station. The terminal transmits a ranging request message including a base station identifier of the first base station to the second base station.
