DATA TRANSMISSION METHOD IN A RADIO COMMUNICATION SYSTEM

WIPO Patent Application WO/2010/077021

A2

The present invention relates to a data transmission method in a radio communication system, comprising the steps of selecting a first reference transmission antenna of a first base station and a second reference transmission antenna of a second base station from among a plurality of base stations, transmitting a first transmission data stream via the first reference transmission antenna, transmitting a second transmission data stream via the second reference transmission antenna to a terminal, time-delaying the first transmission data stream and retransmitting the delayed first transmission data stream to the terminal via a transmission antenna of a first transmission group, and time-delaying the second transmission data stream and retransmitting the delayed second transmission data stream to the terminal via a transmission antenna of a second transmission group. Thus, co-channel interferences can be minimized, and the efficiency in using an antenna and the receiving performance thereof in a radio communication system adopting a multi-antenna technique and a multi-base station system can be improved at the same time.
