Channel types in UTRAN

? Physical channel: form the physical existence of the Uu interface between the UE domain and access domain.

– Different kind of bandwidth allocated for different purposes.

? RNC deals with transport channels:

carry different information flows over the Uu interface and the physical elements.

? Logical channels: different tasks the network and the terminal should perform in different moments of time.

– These structures are mapped to transport channels.
