Physical Cell Identity (PCI) has an essential role in the operation of the Long-Term Evolution network (LTE/LTE-A), and is specifically used to identify cells in the network. An improper PCI assignment might lead to cell conflict with undesirable consequences. To solve the aforementioned PCI's challenges, this paper presents a new graph-coloring algorithm called the Matrix Based algorithm that provides...
Long Term Evolution (LTE) is a breakthrough in broadband technology which aims to support several high level quality and real time multimedia services for the mobile users. This paper proposes a resource block preserver (RBP) scheduling algorithm which optimizes the performance of the downlink transmission system in LTE network. The resource block preserver algorithm has two layers, upper and lower...
The vertex-colouring problem is a well-known classical problem in graph theory in which a colour is assigned to each vertex of the graph such that no two adjacent vertices have the same colour. The minimum vertex-colouring problem is known as NP-hard problem in an arbitrary graph. In this paper a graph colouring algorithm based on modified incidence matrix is proposed for resolving Physical Cell ID...
