摘要

Small cells are envisioned to embrace dynamic time division duplexing (TDD) in order to tailor downlink (DL)/uplink (UL) subframe resources to the quick variations and burstiness of their DL/UL traffic. In this paper, and for the first time, we perform a theoretical analysis on the signal-to-interference-plus-noise ratio performance of dynamic TDD transmissions in homogeneous small cell networks. The significant accuracy of the proposed theoretical analysis is corroborated by simulations. Based on our work, a partial interference cancellation scheme is proposed to reduce the outage probabilities, and it is shown that cancelling one interfering small cell on average is good enough when the traffic load is low to medium to avoid radio link failures.
