Abstract

A method and apparatus of cooperative transmission performed by a transmitter having a multi-antenna in a multi-cell is provided. A first data stream is transmitted to a first base station through a first data layer, and A second data stream is transmitted to a second base station through a second data layer. The first data stream and the second data stream may be generated from different codewords and are respectively mapped to the first data layer and the second data layer.
