In recent year, the 3GPP LTE/LTE-A wireless access technology is a hot research topic. More recently, the femtocell network have received significant attention that many specifications and standards are discussed vehemently. Femtocells are short-range coverage, low cost and low power cellular base stations, designed for the use in a home or small business environment. The purposes of femtocell are to enhance communication quality when the user is located in the weak signal area, share wireless system loadings, and promote spectrum utilization. Although the femtocell network owns several advantages, many challenges in macro/femtocell networks should be solved. In this book, we focus on the resource management and mobility management issues in LTE-based macro/femtocell networks. We survey these two issues, discuss many topics and then provide some feasible solutions in LTE-based macro/femtocell hybrid networks.
