12 3GPP Mobile Communications: WCDMA and HSPA

Patrick Marsch, Michał Maternia, Michal Panek, Ali Yaver, Ryszard Dokuczał and Rybakowski Marcin

In this chapter, we provide a comprehensive overview on wireless communications according to the 3GPP technologies of Wideband Code Division Multiple Access (WCDMA) and High Speed Packet Access (HSPA). These technologies are used in the Universal Mobile Telecommunication Standard (UMTS) belonging to the 3rd Generation (3G) of mobile cellular solutions.

The chapter is structured as follows: In Section 12.1, the WCDMA and HSPA network architecture is explained, such as the roles of the Radio Network Controller (RNC), base stations (which are known in UMTS as Node Bs; these terms are used interchangeably in this chapter) and the interfaces between these. Section 12.2 looks into physical layer aspects, starting first with CDMA basics such as spreading and scrambling, channel estimation, equalization and power control, after which it is explained how actual transmissions take place in WCDMA and HSPA, and which transport and physical channels are defined for this. Section 12.3 then describes radio link procedures, such as cell search, synchronization, registration of a terminal to a cell, call setup, scheduling and handover. Section 12.4 gives an overview on all major features that were introduced to UMTS after Rel. 5, putting a particular emphasis on multicarrier and multiantenna functionality, multipoint transmission, heterogeneous networks ...
