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 format set is
a set of allowed transport formats for a given transport channel.
As a result, it limits the max number of transport blocks that can be transmitted in a TTI, or it limits the max instantaneous bit rate.
Example:
{10ms, turbo coding, static rate matching parameter =1}
{40 bits, 40 bits}; {40 bits, 80 bits}; {40 bits, [...]
Transport format defines the data in a transport block set and how it should be handled by the physical layer.
It consists two parts:
1. semistatic
TTI, error protection scheme, size of CRC, static rate matching parameter,
2. dynamic
transport block size, transport block set size
Example:
{10ms, turbo coding, static rate matching parameter =1}
{320 bits, 640 bits}
