TU02: Cellular Broadband Wireless Packet Access: Design Principles and Systems Engineering Concepts
Instructors: Jose. E. Vargas Bautista, Qualcomm Incorporated, USA and Shuqing Xing, TX, USA

Wednesday 5 April 2006
9:00 – 12:30

Main objective of this tutorial is to provide with a clear and concise view of the fundamentals behind the Physical and MAC Layer of wireless 3G cellular systems for Broadband Packet Data Access. The tutorial will present a detailed and unified state of the art analysis of broadband packet data services in 1xEV-DO Rev. A, HSDPA/HSUPA and TD-CDMA systems. Although, these broadband packet access systems were developed under different standardization bodies, they all share common design principles having only a certain specific flavor. The commonalities and key differences among these three standardized systems, naturally, will become apparent along the course.

The tutorial covers first, in a generalized way, the evolution concepts from the dedicated channel operation to the adaptive scheduled shared channel operation of modern wireless systems. In the first section of the tutorial, the rationale and engineering principles behind the design of CDMA broadband wireless packet access are covered. The second part of the tutorial applies such wireless packet access fundamental design principles to a concise description of the Physical and MAC layers of 1xEV-DO Rev A, HSDPA/HSUPA and TD-CDMA systems. We complete the tutorial with an impartial briefing about current trends of wireless broadband packet services beyond the third cellular generation.

Jose. E. Vargas Bautista received his Ph.D. degree from the State University of Campinas (DECOM/UNICAMP/Brazil) in 1998 and the M.Sc. degree from the Institute of Technology of the Brazilian Spacecraft Center (ITA/CTA/Brazil) in 1994 all in Electrical Engineering. He has over 15 years of work experience in various capacities related to wireless research and development. Dr. Vargas Bautista has been recipient of Federal M.Sc. and Ph.D. program founding from the Brazilian Federal Bureau for the Academic Excellence of Graduate Students (CAPES). He proposed, developed and licensed to CPqD/TELEBRAS an end-to-end Spread Spectrum simulation platform called CeSSSiT (Cellular Spread Spectrum Simulation Toolbox). He spent time in academy as an assistant professor member of the faculty staff at the Sao Paulo State University where he lectured and conducted research projects on wireless internet access. In 1999 Dr. Vargas Bautista joined Ericsson’s Wireless Unit working in Radio Resource and Mobility Management algorithm design for IS-95 and IS-2000 Base Station Controllers. In 2002, Dr. Vargas Bautista Joined Huawei’s CDMA core R&D team in Dallas/TX working on algorithm design, research and optimization of CDMA infrastructure for voice and wireless packet data access. Since 2004, Dr. Vargas Bautista is with Qualcomm Incorporated in San Diego/CA working on different aspects of wireless packet data access through HSDPA, TD-CDMA and 1xEV-DO Rev. A networks. Dr. Vargas Bautista has gained international reputation in the wireless industry. He has conducted workshops on wireless Infrastructure design in the People’s Republic of China and conducted a number of network performance assessments with different wireless infrastructure vendors and network service providers around the globe. He has numerous published research technical papers, in journals and international conferences in Brazil, Mexico, Argentine, the United States and the United Kingdom. (josev@qualcomm.com)

Shuqing Xing received her M.Sc. degree in Electrical Engineering from the University of Texas at Arlington and the B.Sc. degree from the Beijing University of Post and Telecommunications. She is a seasoned wireless professional in the CDMA field with more than ten years experience. She was research scholar in electrical engineer department of Oregon State University. She joined Nortel Networks in 1997 in Richardson/TX working on RF engineering, Network Planning and Optimization of CDMA/TDMA/AMPS systems and in the design of TDMA wireless broadband fixed access infrastructure. Since 2002 she is with a Private Company’s core research and development team in Texas working on CDMA radio resource management algorithm design for 1x and 1xEV-DO systems (Handoffs, Power Control, Supplemental Channel Management, and Forward/Reverse MAC). Her current research focus is in 1xEV-DO rev A. system enhancements for Inter-Operability Management, and Radio Resource Management (shuqingxing@yahoo.com)
