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: 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.
