Below is an example of transport characteristics of an interactive service through DCH
The below is an example of the transport characteristics of a Signaling Radio Bearer through DCH
These two DCHs are multiplexed into a CCTrCH with the following TFCS (transport format combination set).
For a given TTI, TFC (Transport format combination) is chosen and used.
Transport channels care about how and which characteristics the data from MAC layer are transmitted through the radio interface.
It is not about what information which logical channels take care.
Thus, two main categoires: (1) dedicated and (2) common
1. Dedicated
DCH (Dedicated Channel): DCH includes either user or control information.
In the case of single service, a usual situation [...]
