In mobile communication networks under bursty traffic conditions the interference experienced by the users varies constantly. Therefore, the periodic reporting of channel state information becomes inaccurate and the link adaptation performance deteriorates. In this work, a coordinated scheduling scheme is proposed to improve the link adaptation performance(More)
In this paper, we investigate user association and resource block (RB) allocation in downlink heterogeneous cellular networks. Our goal is to jointly optimize user association and RB allocation to maximize network throughput while taking into account fairness among users. To effectively control interference, RB muting is employed. The problem is addressed(More)
This work addresses the problem associated with coordinating scheduling decisions among multiple base stations in an LTE-Advanced downlink network in order to manage inter-cell interference with a centralized controller. To solve the coordinated scheduling problem an integer non-linear program is formulated that, unlike most existing approaches, does not(More)
We address the problem of small cell deployment planning in LTE networks. The wireless network is modeled with multiple heterogeneities such as hotspots in the mobile user distribution, site-specific acquisition costs and different types of small cell base stations with different cost and transmit power. The objective is to lower the maximum load of any(More)
A cooperative power control scheme is proposed for heterogeneous cellular networks to improve the throughput of the users connected to low transmission power cells, e.g., femto-or pico cells. The proposed scheme dynamically reduces the transmission power of the dominating interfering macro base station, to effectively increase the SINR conditions of the(More)
