摘要：
Dynamic time division duplex is a promising 5th generation (5G) mobile communication technology that can improve spectrum efficiency by meeting the demands of asymmetric and rapidly varying uplink and downlink traffic. However, when two adjacent cells have opposite transmission directions and share a time slot, it causes serious interference called crossed-slot interference. In this paper, we show that a crossed time slot shared by two adjacent cells can improve the signal-to-interference ratio (SIR) depending on the location of the user equipment (UE). We mathematically derive a beneficial UE region and show through simulations that the opportunistic usage of crossed-slot transmissions can mitigate interference and achieve a high SIR.
