Essential HSPA and HSPA+
HSPA training course description
HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) provide speeds of upto 14Mbps downlink and 5Mbps uplink. This theory-based course provides an overview of the 3GPP R5 and R6 HSDPA/HSUPA standards and the technologies which are involved. The HSPA+ R7 enhancements are also covered.

Who will benefit?
Anyone working with HSPA.

HSPA course prerequisites
Essential UMTS

HSPA training course objectives
By the end of the course delegates will be able to:
  • Explain the relationship between HSPA and UMTS
  • Describe the benefits of HSPA/HSPA+
  • Explain the HSPA/HSPA+ technical enhancements.
  • Explain packet flows in HSPA/HSPA+.
  • Recognise the migration issues involved with HSPA/HSPA+

Duration: 2 days

HSPA training course contents

UMTS review
UMTS architecture, components, interfaces, protocols, W-CDMA, standards, 3GPPr5, 3GPPr6, evolution to HSDPA and HSPA.

HSPA basics
What is HSDPA, what is HSUPA, key features, system capacities, data rates, delays. Key concepts: Adaptive modulation and coding (AMC), QPSK, 16QAM, HARQ, MAC-hs, multiplexing, subframes.

HSPA channels
Logical, transport, physical channels, dedicated vs. shared channels, HS-PDSCH, HS-SCCH, HS-DPCCH, code multiplexing, E-DCH, Enhanced DPCCH.

MAC-architecture
Controlling HS-DSCH, flow control, buffering, priority queues, packet scheduling, fast packet scheduling, Selecting modulation and coding. HARQ: Packet retransmissions, Incremental redundancy, comparison with ARQ, TFRC. MAC-d, MAC-c/sh, MAC-hs, MAC-es, MAC-e.

HSPA migration
HSDPA in the Radio Access Network (RAN), reuse of existing UMTS components, changes required, Impact on Iub/Iur interfaces, new and modified NBAP procedures, backwards compatibility.

Packet flows
Packet data session setup, simultaneous voice and data, QoS, TCP flow control, WCDMA packet scheduler, mobility procedures.

HSPA phase 2 (3GPP r6)
What is evolved HSPA? Speeds. Multiple Input Multiple Output (MIMO). Optional all IP architecture. R8 and LTE.
