Physical channels and mapping of transport channels
onto physical channels (FDD)
(Release 9)


The present document describes the characteristics of the Layer 1 transport channels and physicals channels in the FDD
mode of UTRA. The main objectives of the document are to be a part of the full description of the UTRA Layer 1, and
to serve as a basis for the drafting of the actual technical specification (TS).
