Dynamic TDD transmissions in homogeneous small cell networks

In this paper, we investigate the performance of dynamic time division duplexing (TDD) transmissions with various kinds of interference management strategies, i.e., cell clustering (CC), power control and interference cancellation (IC), as well as their combinations in homogeneous small cell networks. We present extensive results on network performance in terms of downlink (DL)/uplink (UL) wide-band (WB) signal-to-interference-plus-noise ratio (SINR), 95-, 50- and 5-percentile user equipment (UE) packet throughputs (UPTs). We also study the impact of high-order modulation schemes on dynamic TDD. Our work shows that, when the traffic load is low to medium, an advanced dynamic TDD scheme with UL power boosting (ULPB), IC and full flexibility of TDD configuration is shown to immensely outperform the static TDD scheme by approximately 30∼60% and 210∼300% in terms of the DL and the UL UPTs, respectively.
