The deployment of femtocells is beneficial for both users and operators. On the one hand, it
can be used to improve the indoor coverage, but on the other hand it will inevitably produce …

Network operators are constantly trying to increase their capacity and coverage at minimal
cost. Femtocells are low cost base stations that are deployed indoors either by home users …

In wireless network system the resources are limited. Therefore, managing resources is
considered as a challenging task. The resource are distributed among attached UEs, so …

Femto cells have been integrated into 4G Long Term Evolution (LTE) cellular network
architecture to efficiently address the coverage and capacity issues faced in indoors and at …

3G networks evolve to Long Term Evolution (LTE) in order to satisfy the increasing demands
of data rates in both downlink and uplink, OPEX/CAPEX operators' requirements and needs …

Due to the increasing demand for higher data rates by mobile users, the deployment of
femtocells under macro coverage has been adopted by 3GPP LTE-Advanced systems as …

Interference mitigation between femtocells and the surrounding macrocells is one of the
major challenges in femtocell deployment. This paper proposes a system architecture of …

LTE-A addresses the challenges of coverage block holes and increase in user density with
new features, such as small cell and femto cell. Small cell can be an inexpensive substitute …

In this paper, we consider the problem of resource allocation in two-tier networks taking into
consideration nondense femtocell deployments. The following limitations can be remarked …

Femtocells are receiving considerable interest in mobile communications as a strategy to
overcome the indoor coverage problems as well as to improve the efficiency of current …
