The transport channel is a concept applied to the interface between the physical layer and the MAC layer.
All transport channels are unidirectional.
The physical layer operates in 10-ms time slices in the connected mode (HSDPA case: 2-ms).
The data is sent using transport blocks.

First, think about the definition of spreading factor (SF): the number of chips for each symbol.
Second, remember that a chip duration is fixed.
Third, what is symbol? Each symbol can represent some amount of bits. e.g., QPSK, each symbol represents 2 bits.
SF: 2 SF vs. 512 SF
Time: 2*delta vs. 512*delta
Data: 1 symbol vs. 1 symbol
where delta [...]
