Abstract
The explosion in the mobile broadband data usage and the advent of applications with different uplink and downlink quality of service requirements has triggered an increased interest in time division duplexing (TDD) systems. Despite the flexibility it offers in dynamically changing the uplink and downlink transmission schedules according to the traffic variations in a given network, the TDD mode of operation introduces increasing complexity in managing the interference generated by the concurrent uplink and downlink tranmission in different cells. In this paper, we present a statistical framework for the modeling of interference in TDD systems and the analysis the impact of dynamic switching point configuration on the TDD-based network operation. The probability density function (pdf) for each type of interference is first derived using moment generating functions. Then, interference maps are generated to analyze the impact of TDD operation in a given network.
