Martin Haardt; Anja Klein; Reinhard Koehn; Stefan Oestreich; Marcus Purat; Volker Sommer; Thomas Ulrich

The third-generation mobile radio system UTRA that has been specified in the Third Generation Partnership Project (3GPP) consists of an FDD and a TDD mode. This paper presents the UTRA TDD mode, which is based on TD-CDMA. Important system features are explained in detail. Moreover, an overview of the system architecture and the radio interface protocols is given. Furthermore, the physical layer of UTRA TDD is explained, and the protocol operation is described.

The physical layer of UTRA TDD

Martin Haardt; Anja Klein; Stefan Oestreich; Marcus Purat; Volker Sommer; Thomas Ulrich

The third generation mobile radio system UTRA that has been specified in the Third Generation Partnership Project (3GPP) consists of an FDD and a TDD mode. This paper presents the physical layer of the UTRA TDD mode, which is based on TD-CDMA. Important system features are explained in detail. The physical layer is responsible for the transmission of transport blocks over the air interface. This includes forward error correction, multiplexing of different transport channels on the same physical resources, rate matching, modulation, spreading and RF processing.
