Mastering HSPA Protocols and Signaling

High Speed Packet Access (HSPA) enhances the packet data services provided in UMTS (WCDMA) by increasing the data throughput and reducing delays. The HSPA network offers UMTS subscribers much higher data rates, in both the uplink and downlink. HSPA has three key technology enhancements: link adaptation using adaptive coding and modulation, incremental redundancy and fast scheduling. This course describes the key benefits and challenges of the HSPA technology and the enhancements to the signaling protocols to support HSPA. The focus is primarily on the radio network with emphasis is placed on the new channels and related operations. The overall operations of HSPA, starting from measurements and ending with HARQ, are addressed in detail. The key concepts in the course are tied together with several scenarios that offer insight into the reconfiguration of the radio link and mobility.

Learning Objectives

After completing this course, the student will be able to:
• List the driving forces behind HSPA
• Describe the key technological enhancements
• Sketch the network architecture, related protocols and messaging architectures of HSDPA/HSUPA networks
• Explain how incremental redundancy will be used to improve the retransmissions mechanisms in both the downlink and the uplink
• Describe how the fast scheduling functions will reduce the delays associated with sending packet data to the end users
• Step through the establishment of a packet data session and reconfiguration of the radio link
• Identify the signaling enhancements required to set up an HSPA-based data call
• Describe the detailed operations of HSDPA such as CQI determination, DL scheduling and HARQ operation
• Describe the detailed operations of HSUPA such as grant assignments, E-TFC selection and HARQ operation
• Step through various handover scenarios including inter-radio access technology (HSDPA/HSUPA to R99 to GPRS)
• Sketch the message flow of a multi-service scenario

Intended Audience

This course is primarily intended for a technical audience, including those in RF engineering, systems engineering, network engineering, product support, operations, and anyone seeking a more in depth understanding of the HSPA.
