In this paper, a hybrid frequency al ocation scheme for densely-deployed smal cel s is proposed to improve system capacity and minimize inter-cel 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 al ocation schemes to appropriately deploy smal cel s.
