As the demand for reliable high speed data transmission increases, the capacity of downlink cellular multiple-input multiple-output (MIMO) systems is of much interest. Unfortunately, the capacity analysis regarding the frequency reuse factor (FRF) is rarely reported. In this paper, theoretical analyses for both ergodic and outage capacities for cellular MIMO systems are presented. The FRF is considered and a hybrid frequency reuse scheme is proposed. It is shown by the numerical results that the proposed scheme can greatly alleviate the coverage problem of single-frequency-reuse cellular systems.
