We discuss a distributed utility-based algorithm for downlink carrier allocation in a multi-carrier system. The proposed dynamic frequency selection (DFS) algorithm aims to maximize the sum utility of the whole system. To achieve this goal, each base station (BS) selects the carrier allocation strategy to maximize a surplus function comprising both own cell utility and utility prices received from...
We study a distributed approach for Primary Component Carrier (PCC) selection to manage interference and to improve cell edge performance in a heterogeneous network. To avoid cell outage caused by PCC selection based on path loss between neighboring base stations (BSs), we argue that carrier reselection based on handover measurements performed by the User Equipments (UEs) is necessary. We propose...
