摘要： The present invention relates to a method for changing a preamble in a moving network system, and a system for same. The method comprises the steps of: enabling a base station to select a relay, to change a preamble thereof from at least two relays using a first preamble; enabling the selected relay to alternately transmit a signal using the first preamble and a signal using a second preamble to at least one terminal controlled by the selected relay; enabling the selected relay to judge whether the preamble of said at least one terminal is completely changed; and enabling the selected relay to transmit only the signal using the second preamble to said at least one terminal if the preamble is completely changed. The method for changing a preamble in a moving network system and the system for same according to the present invention minimizes communication cutoff time under the condition in which a mobile relay should change a preamble, to thereby effectively provide all terminals with information without a loss, and improve the utilization of a moving network.

摘要： The invention relates to a data transfer method in a multi-hop relay system. The data transfer method comprises: a step for allowing a base station to receive from a first terminal the channel information (Hd,1) between the base station and the first mobile station, a step for making the base station generate an interference cancellation precoding matrix using Hd,1, a step for forcing the base station to transfer first data to a relay station, and a step for making the relay station transfer the first data to the first mobile station and forcing the base station to transfer second data to a second mobile station, wherein the second data is converted using the interference cancellation precoding matrix. According to the disclosed data transfer method in the multi-hope relay system, the base station transfers data to another mobile station efficiently when the relay station transfers data to a mobile station. Therefore, the data transfer method is able to efficiently use the resources wasted in an existing data transfer method and improve the total data transmission rate of the base station.
