<p><P>PROBLEM TO BE SOLVED: To provide a method of determining an optimal transmission mode and a data frame structure for determining the optimal transmission mode, in a data transmission system that uses relays. <P>SOLUTION: A method of determining, by a mobile station, an optimal transmission mode for transmitting data from a base station to the mobile station comprises generating first channel state information, with respect to a path from the base station to the mobile station; generating second channel state information, with respect to a path from a relay to the mobile station; receiving, from the relay, third channel information with respect to a path from the base station to the relay; determining an optimal transmission mode from among a plurality of transmission modes, based on the first channel state information, the second channel state information and the third channel state information; and transmitting the determined optimal transmission mode to the base station. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
