WCDMA ( 3G ) Channels
Channel Mapping
· The data can be
sent through logical layer via different channels in the transport layer.
· And also one
transport channel can be sent via different physical channels.
· These selection
of channels in the transport and physical layer depends on the data itself and
radio resource management and its parameters.

COMMUNICATION PROCESS
•
Each layer has its own specified
functions and provides specific services for the layers above
•
It is important to define the
interfaces between different layers and the functions within each layer.
•
The way a function is realized
within a layer is not predicted.
•
Logically, the communication between
functions always takes place on the same level according to the protocols for
that level.
