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: Provided are a method and an apparatus for performing a synchronous hybrid automatic repeat reQuest (HARQ). When a variable transmission time allocation is allocated per HARQ process, resource allocation information including a duration field corresponding to a length of a transmission time interval (TTI) allocated to each of the HARQ processes is transmitted. After the resource allocation information is transmitted, it is determined whether an HARQ error occurs at a predetermined timing and if it is determined whether the HARQ error occurs, the HARQ error is handled.

Abstract: Disclosed is a method and apparatus for random access in a wireless communication system. In a communication environment in which a first terminal and a second terminal coexist, a base station receives a random access identification signal from one among a first terminal and a second terminal. The base station transmits a busy signal in response to the random access identification signal. After that, the base station receives data from the terminal having transmitted the random access identification signal.

Abstract: A method of managing a resource is provided by a base station. The base station allocates a resource to a terminal, and generates a downlink control channel including information of the allocated resource and a transmission time of a next downlink control channel. Further, the base station transmits the downlink control channel to the terminal.

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: 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.
