    摘要： Disclosed is a symbol synchronization method in an OFDM-based communication system which includes multiple access nodes supporting wireless connection of terminals, supports multi-connection of each terminal for the access nodes and performs synchronization by means of a cyclic prefix. The symbol synchronization method includes monitoring connection of a new access node; setting a number of times by which the new access node transmits equal symbols and a number of times by which at least one existing access node transmits the equal symbols when the connection of the new access node is detected; transmitting the equal symbols by the determined number of times by each access node; and performing synchronization by means of the symbols received from the access nodes by the terminal.

    摘要： Frame structures, a method and an apparatus for resource allocation in a wireless communication system based on a full duplex relay are provided. The method for a centralized resource allocation in the wireless communication system based on the full duplex relay includes receiving channel information from a plurality of mobile stations (MSs) and relay stations (RSs); scheduling radio resources for a link between a base station (BS) and the MS and a link between the BS and the RS using the channel quality; constituting a first radio resource region for the link between the BS and the RS and a second radio resource region for the link between the BS and the MS; and scheduling radio resource for a link between the RS and the MS by reusing the first radio resource region. The relay link resource is reused in the full-duplex relay structure, and the system capacity can be raised by minimizing the interference in the resource utilization.
