[Abstract] In this paper, a hybrid frequency allocation scheme for densely-deployed small cells is proposed to improve system capacity and minimize inter-cell interference between multi-tier heterogeneous networks. Closed-form solutions are achieved with theoretical results for proposed downlink capacity model, and key parameters are analyzed. Numerical results show that capacity can be improved by using hybrid frequency allocation schemes to appropriately deploy small cells.
