Abstract

The present invention relates to a method for reporting channel information to a base station terminal and to a device therefor, and a method and device for cooperative communication with at least two transmission antennas and at least two base stations which receive feedback channel information directly or indirectly through terminals and forwards the information. In particular, the method comprises the following technical features: a transmission step for transmitting a signal to a terminal through at least one antenna group from among at least two antenna groups having different polarizations to at least one base station among at least two base stations in a cooperative multi-cell communication system; and a transmission step for transmitting a signal to a terminal using an antenna group with a polarization different from the at least one antenna group from among at least two antenna groups having different polarizations, of one base station while excluding at least one base station among the base stations.
