Base Station Cooperation for Multiuser MIMO: Joint Transmission and BS Selection

Abstract

The predicted enormous capacity gain of multiple-input multiple-output (MIMO) systems is significantly limited by co-channel interference (CCI), or by realistic outdoor propagation environments. In this paper, a common framework is proposed for the study of cooperative base stations (BS), to address those problems encountered on downlink of multicell multiuser MIMO systems. Specifically, both joint transmission (JT) and BS selection among cooperative base stations are analyzed and compared with each other. Some other advantages of BS cooperation are also explored including the power gain, channel rank/conditioning advantage, and macro-diversity.
