Nationwide Spectrum Sharing of Mobile Network Operators with Indoor Small Cells

In this poster, we propose a novel technique to share licensed spectrums of nationwide mobile network operators (MNOs) with in-building small cells by exploiting the external wall penetration loss of any building and introducing the time-domain eICIC technique. The system architecture and co-channel interference management are discussed and the outperformance of the proposed technique is shown. The proposed spectrum sharing technique can help overcome the scarcity of licensed spectrums of an MNO and boost the indoor data rate and capacity without additional investment on licensing spectrum for indoors.
