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.

Abstract: Disclosed are operation methods of communication node supporting direct communications in network. The operation method comprises obtaining scheduling information configured for the direct communications from a first base station; identifying modulation and coding scheme (MCS) information and radio resource information included in the scheduling information; and transmitting, to a second UE, a first message to which a MCS indicated by the MCS information is applied through radio resources indicated by the radio resource information. Therefore, performance of a communication system can be enhanced.
