High Speed Packet Access Evolution - Concept and Technologies

Janne Peisa; Stefan Wager; Mats Sågfors; Johan Torsner; Bo Göransson; Tracy Fulghum; Carmela Cozzo; Stephen Grant

In this paper we present the main concepts of high speed packet access evolution currently being standardized in 3GPP. In general HSPA evolution consists of introduction of MIMO, higher order modulation, and protocol optimizations and optimizations for voice over IP. We describe these improvements in detail and show that HSPA Evolution can reach performance comparable to those of long term evolution of UMTS terrestrial radio access network in a 5 MHz deployment.
