Preface During the past years, there has been a quickly rising interest in radio access technologies for providing mobile as well as nomadic and fixed services for voice, video, and data. The difference in design, implementation, and use between telecom and datacom technologies is also getting more blurred. One example is cellular technologies from the telecom world being used for broadband data and wireless LAN from the datacom world being used for voice over IP. Today, the most widespread radio access technology for mobile communication is digital cellular, with the number of users passing 3 billion by 2007, which is almost half of the world's population.
Computing the transport-block size. 21. Timing relation for uplink grants in FDD and TDD configuration 0. 22. Processing of L1/L2 control signaling. 23. CCE aggregation and PDCCH multiplexing. 24. Example of mapping of PCFICH, PHICH, and PDCCH. 25. Principal illustration of search spaces in two terminals. 26. LTE downlink transport-channel processing. Dashed parts are only present in case of spatial multiplexing, that is when two transport blocks are transmitted in parallel within a TTI. 27. Code-block segmentation and per-code-block CRC insertion.
However, already today, data rates well beyond 2 Mbps can be seen in deployed 3G systems. 3. Research on 3G In parallel with the widespread deployment and evolution of 2G mobile-communication systems during the 1990s, substantial efforts were put into 3G research activities. In Europe the partially EU-funded project Research into Advanced Communications in Europe (RACE) carried out initial 3G research in its first phase. 3G in Europe was named Universal Mobile Telecommunications Services (UMTS).
