Cross-Layer Optimization in Terminals

The innovation pace of the wireless communication world is breathtaking, not only due to the fierce competition, but also due to the yearly cadence with which standards bodies deliver a new set of functionalities and services to be supported. In this very dynamic context, optimizing products and differentiate against the competitors is key for all those who want to be successful in a make-or-break market. This paper therefore describes some key cross-layer optimization techniques of mobile phones, focusing on cellular protocol stack access stratum enhancements, power optimizations to memory system and finally cross-layer impact on tools for SW development.
