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 newchannels 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.
