Abstract

An apparatus and method for processing collaborative Multiple Input Multiple Output (MIMO) is provided. A terminal searcher searches for terminals capable of Collaborative MIMO depending on a basic capacity exchanged with terminals. A terminal information collector collects at least one of position information, channel quality information, Carrier to Interference and Noise Ratio (CINR) information, power allocation ratio information, and Modulation and Coding Scheme (MCS) level information, for the terminals capable of Collaborative MIMO. A terminal grouper groups the terminals capable of Collaborative MIMO based on the collected at least one information, increasing QoS and ensuring efficient utilization of resources.
