Ergodic Capacity of Interference Coordinated HetNet with Full-Duplex Small Cells

Abstract:
Full-duplex small cells provide a promising solution for meeting the capacity requirements of future wireless networks. The main objective of this paper is to analyse the sum ergodic capacity of full-duplex small cells operating in heterogeneous environments. A theoretical framework is developed and closed-form approximations for sum ergodic capacity have been derived. In order to evaluate the benefits of full-duplex small cells, the proposed framework compares three distinct scenarios: full-duplex small cells with full-duplex devices, full-duplex small cells with half-duplex devices, and the conventional half-duplex heterogeneous network.
