摘要： Provided is a multiple input multiple output (MIMO) communication method and system that may exchange information associated with a coordinated rank for a neighbor cell. In a MIMO communication system, a target terminal may feed back the information associated with the coordinated rank to a serving base station, and the serving base station may exchange the information associated with the coordinated rank with the neighbor base station. The serving base station may perform precoding based on the exchanged information associated with the coordinated rank.

摘要： A multiple input multiple output (MIMO) communication system using an explicit feedback is provided. In the MIMO communication system using the explicit feedback, a receiver may generate an explicit feedback vector by calculating an explicit channel matrix, and by vectorizing the explicit channel matrix or an explicit channel matrix processed using a predefined function. Feedback information generated based on the explicit feedback vector may be provided to a transmitter. The transmitter may reconfigure the explicit channel matrix or the processed explicit channel matrix based on the feedback information. The transmitter and the receiver may share the explicit channel matrix or the processed explicit channel matrix using an adaptively transformed codebook.
