    • Examining the main technical enhancements brought by LTE-Advanced (LTE-A), this book thoroughly covers 3GPP R10 and R11 specifications. Using illustrations, graphs and real-life scenarios, the authors systematically lead readers through this cutting-edge topic to provide an outlook on existing technologies as well as possible future developments. The book is structured to follow the main technical areas that will be enhanced by the new LTE-A specifications. Topics covered include: 3GPP milestones and outlook to Release 11; LTE-Advanced in IMT-Advanced process in ITU-R; Downlink Carrier Aggregation; Coordinated Multipoint Transmission (CoMP); Heterogeneous Networks; and HSPA Evolution. It concludes with an outlook towards Release 11 and 12, introducing 3GPP Release 11 study and work items.
