Course Overview:
This course presents a detailed technical discussion of the existing 3GPP R5 and R6 HSDPA / HSUPA specifications and the R7 enhancements that have been introduced to increase throughput, reduce latency, conserve power and reduce signalling overhead (commonly referred to as HSPA+ features).
The course starts on WCDMA refresher making sure the main concepts & techniques are clear, and then continue covering the Node B processes for scheduling, fast link adaptation and Hybrid-ARQ (HARQ), the physical layer, the new types of modulation and transport formats. A traffic case in which a user is allocated with HSDPA resources is presented. Calculations of HSDPA data rates are also described. Special attention will be provided to the Protocol Stack and data session call flow scenarios showing the message flow, the protocols and SW entities involved.
