Resource Allocation in Heterogeneous Small-Cell Networks with Interference Avoidance Admission

In this paper, we consider a heterogenous small-cell network (HSCNet) with co-channel deployment and investigate the throughput performance of the proposed admission control algorithm based on a new received interference constraint at the small-cell base station (SCBS) nodes. In the considered co-channel heterogenous network, by utilizing the proposed admission algorithm based on the amount of received interference generated at the neighboring macro users, the new user is admitted at the small-cell network (SCNet) while ensuring that no harmful interference is caused to the adjacent macro users. For the proposed admission algorithm, we investigate the achievable effective capacity performance of the SCNet subject to maximizing the throughput performance of the SCNet. Finally, we sustain our theoretical analysis by numerical results.
